I cannot find the app for apple.

We don't have the app for iOS yet but we could probably do it quickly given we use Cordova.

Keep in mind that Apple will probably reject it from the store but I guess jail broken phones could use it.

This is great!

Thanks  ;D

Just updated the post with some more info and more links.
We got 3 languages in testnet that can be manually reached and should be almost final, respectively french italian and spanish (https://test.greenaddress.it/fr , https://test.greenaddress.it/it , https://test.greenaddress.it/es)

bitcoin.org wallets pull request https://github.com/bitcoin/bitcoin.org/pull/360

Hello,

We added a blog, a non stable API in development and a design/implementation document regarding the GreenAddress wallet service .

All can be found on this first blog post:  http://blog.greenaddress.it/2014/04/05/firstpost-updates/

Why does the name of this service remind me of a proposal Mike Hearn floated last year in the Bitcoin Foundation forums?

No it was worst it was a proposal by mt gox to make their address special to miners. https://en.bitcoin.it/wiki/Green_address

The idea was mostly independent in early 2013 but it is quite similar to an idea that Gavin had (see https://gist.github.com/gavinandresen/5616606)
The term greenaddress as far as I know was coined by Jan Vornberger (of Bitcoinwalker and Hive fame) and in the original incarnation didn't really work but we hope to provide a better solution for it to work (out of band and from a P2SH 2of2, more details in the pdf).

Your site looks absolutely awesome. Best of luck. I have one doubt though. In the "Send Money" page, there's an option like this:
I assume the recipient paying the fee means it will be deducted from the amount to be sent?

poordeveloper:

Correct, that's nothing more than picking whether the fee will come out of the amount you are sending or from the reminder in your wallet.
It's probably not a particularly useful feature and I'm not sure whether it should stay as it may confuse some users.

What do you think?

At first, I must say I was a bit confused - at first I thought maybe it was a new protocol feature I hadn't heard about until now (I've been out of the Bitcoin world for a month of so... and things change fast). It took me a while to actually see that no such feature exists in the protocol, and so this should mean whether the fee is included or not in the amount to be sent (but still I wasn't sure - I could even think you implemented this system for payments to GreenAddress users, since normal Bitcoin TXs don't have this option).

With this option, I'd add the data in a table, like the Cryptsy withdrawal forms do.

I'd clarify this in the options themselves (Me/Recipient), with a tooltip maybe.

thanks for the suggestion and sorry for the confusion.

 I have not tried Cryptsy, will have a look ;)

We used to support qrcode scanning only for Android, now we support iOS safari and all other browser that support it.

http://blog.greenaddress.it/2014/04/07/ios-bitcoin-and-qr-codes/

Cheers!

Great conept! I'll give it a try!  ;D

Let us know what you think after you try it and what you'd like improved !  ;D

http://blog.greenaddress.it/2014/04/30/reusing-addresses-is-bad-mkay/

You should post an excerpt so more people click and read the article. It's actually informative and well-written so I think many users will benefit from it.
Just a quick question - when using the "sweep" function - are there any fees?

Hi, there are network fees but GreenAddress does not charge for any usage of the wallet.

We will only change for some premium services and promptly tell the user if so.


See below cut and paste of the article

new blog post http://blog.greenaddress.it/2014/05/12/amsterdam-bitcoin-2014-payment-protocol-stealth-addresses-coinjoin-and-merge-avoidance/

Hi, I just created a greenaddress.it wallet and played around a bit, overall I am quite impressed with the concept and its execution. Just a few thoughts:

1) nLockTime for user refund is nice and all, but the time-locked refund tx is only provided after the new incoming tx has been broadcast, so your nLockTime solution does not protect me, if for example, if I receive a payment in a state where greenaddress.it keys have already been lost, for example. Of course this is the way the service has been designed, so I'm not sure if there exists a solution. Have you any thoughts about this? Is there a way to design a payment protocol perhaps such that the sender only signs the inbound tx after the nLockTime tx has been provided to the recipient?

2) Micropayments. I notice that the way micropayment channels are set up is very similar to how greenaddress.it works. I wonder if you have given any thought to integrating a micropayment system into your wallet? I have been waiting to see a real solution for receiving off-blockchain, zero-fee transactions which doesn't require the sender to have an account with any specific third party like Coinbase for example.

Good luck with your service!

Hi, I'm loving the chrome app for this (and can't wait for an iOS version to arrive, hopefully soon!), but I do have two questions to ask...

The first is about the NLockTime thingy... How can I (provably) tell if my funds are in an NLockTime state? Does some information exist on the blockchain or something? Sorry if this is a silly question but it just seems that currently I am just taking your word for it when I switch the toggle in the settings panel...

Secondly, how can I check which address my timelock funds are set to be sent to at expiry? Also, is ti possible to change this address (I suspect not)...?

Thanks

EDIT: Also would liek to ask about the chrome app: I don't seem to be able to send using it? The app just hangs before it gets to the 2FA screen (which it can thankfully reach from my iPad).? Any ideas how I can get sending to work on the chrome app?

Thanks again

i only want to receive bitcoins

1,    i went to Receive Money  tab , no addresses and no generate new address button
2,    ok then try  "show uri and addresses"  button  --> ohh a new address shown (my first address)
3,    logout , login
4,    i went to Receive Money  tab , no receiving addresses shown ,  wtf? 
5,    ok then try  "show uri and addresses"  --> ohh and i got another address  wtf?????  new address?   i clicked on "show" not generate , (there is no generate new address)


i generated 4 addresses (with the show button) before i noticed that my addresses can be only seen when i click "show previously generated addresses"  button   -->  this is a very bad  UI (user interface) 
why the "show uri and addresses" button generates address , and not only showing the last one?    this is very bad UI too

i think you should reconsider this misleading UI

Hello,

I am not sure I understand exactly your issue, can you help me understand it better?

Let me start from saying that unlike other wallets generating new addresses in GreenAddress does not require manual backup as the wallet is deterministic.
On top of that, it is the norm in bitcoin security and privacy to avoid reusing addresses.
Last, we don't automatically show an address as you may wish to receive bitcoin via paper wallet scan or by manually sweeping some keys as opposed to provide someone with an address.

If we generate the address anyway and that is not distributed it gets wasted, on the other hand there is no way for us to know once we display it if it is ever given out as it can be used later for what we know and by default we avoid but not prevent address reuse.

What is the actual need or issue you suffered? You can reuse addresses but we do not do that as a default as it is bad for both your privacy and potentially security.

For more details you can see this blog post http://blog.greenaddress.it/2014/04/30/reusing-addresses-is-bad-mkay/

Hope this helps!

Thanks!

@e4xit

is it possible on your chrome app computer you have a firewall for outbound connections on port 8081 or other ports used by electrum servers?
We have a patch coming for this that in case there's firewall issues allows the user to decide to go ahead anyway and not use the extra checks provided by this extra checks we do.

If is not that I need to check a little more about the version you are running of chrome and the app so i can try to reproduce.

Thanks!

i wont send more than 100 BTC to an address that i have never tested before , and i think not i am the one

so when i am trying a new wallet service :

1,  send only 0.1 BTC to the wallet
2,  send another 0.01 BTC to the wallet to the same address
3,  send back 0.1 BTC to my currently used wallet   (testing the other way)
4,   after everything worked , i will send 10-1000 BTC to the new wallet (same address)

I understand your point of view.

Sending a tx is not the best way to test the address, as gmaxwell suggested in a short conversation on irc #bitcoin something better may be signing a message but unfortunately i don't think it is the most user friendly way.

You can reuse addresses in our service and it wouldn't be any worse than reusing addresses in other services, in fact, because of multisignature and deterministic signatures it is  better but we still prefer to discourage things that may ruin your privacy or security where possible.

Is there something we can do to improve your experience but at the same time avoid impacting privacy and security?
We could have a settings option that shows you the last one at your own risk such that you don't have to find it in the list.

Conversation below for reference:

Hi :) very nice service.

But are you planning to implement more signature features - like 2 of 3, 3 of 5, etc? I somehow feel that with multisignature it's possible to lose part of key.

We are planning to be interoperable with other wallets that support n of m for multiple people authorizing transactions.

We also have implemented subwallets which are currently available via the API and that we will soon add to our UI such that you can create subwallets with any security settings you like including 2of3.

More on this soon!

Hi tryexcept,

I am using a work computer for this so entirely possible that port 8081 might be blocked... I will try to run a test for it when I am back at work tomorrow (there must be a website which can check an open port right?)

Hi e4xit,

We just pushed a new update of the app which should now work with firewalls blocking electrum and allowing you to ignore that if you have no alternative.
I need to make some more changes for android and then will push to github both, for now I just updated the chrome store.

Hope this helps!

what if i lose my phone (my "telephone number") , so i cant get the sms to the  Two factor authentication  ( so i cant make any "action"/change )
How can i access to my bitcoins  (for sending) ? 

You can always set a Gauth code which you can keep in a safe place as a backup or you can set some other 2FA option.
To disable a 2FA you need 2FA so you are advised to configure two or backup your gauth if you use that alone.

I just noticed something disturbing?


"Server assisted bitcoin wallet which runs in your browser or on your phone or as a local unminified/inspectionable App."


 Server assisted, doesn't this mean you control all keys and could easily steal funds?

 I also just seen this on reddit:


EDIT: Link to Greenaddress using deceptive buissness practices - https://bitcointalk.org/index.php?topic=670613.msg7587965#msg7587965

EDIT: Link to Greenaddress using peddlers to hide that on reddit - http://www.reddit.com/r/Bitcoin/comments/29fdhu/greenaddress_is_using_peddlers_to_hide_bad/


 I'd think twice before using greenaddress.

Server assisted multisignature sir!

You should know, you are trying to create a multisig wallet yourself! Let us know if you want any tip of code sharing! We are on github!

You surely have no problem scamming people with a central server, do you understand how big of a risk your putting on people with that?!?

also did you already forget?

http://www.reddit.com/r/Bitcoin/comments/29fdhu/greenaddress_is_using_peddlers_to_hide_bad/

You have no problem using shills, and sock puppets. Do you think people are stupid enough not to notice?

You must of glossed over your criticism thread, alot of people saying they don't trust greenaddress.

Alsono one knows greenaddress, you have yet to make news. If you want multisig awareness don't cry over things, address them then start a campaign to spread awareness.


   -Calvin

 It appears GreenAddress is attempting to run a scam, or just using children tactics.

It appears FrozenBit has been brought into this mix somehow. I have greater assumptions of why this is, mostly because greenaddress is pointing fingers.

If this is about what was on the front page of reddit yesterday which I've been messaged about I never clicked on that link and didn't know in detail what it was about. If you respond to bad criticism by feeding the troll you're just hurting yourself. Don't point fingers, instead address it which I haven't seen you do. However, I can assure you we are NOT behind this.

 Anyway I invite you to read about our service http://frozenbit.io, and wait for launch. Since we're both multisig I don't see what you're complaining for. Multisig is about awareness. All of my talks with https://www.BitGo.com have been about spreading awareness not crying when someone comes into the mix who does things a little different. I think you could learn some things from that playbook.

 Anyway the Gist is, don't point fingers and address what this guy is saying. It's not that hard is it?

 Now you can put your finger down.

 However, lawrence appears to be trolling, must not feed trolls.

EDIT: It doesn't matter if they're affiliated with FrozenBit or not. It's a matter of their opinion on what they see above, if you can't take criticism you're in the wrong business.

 To answer your questions

1.) Is that a question?

2.) Is that a question?

3.) Ok

4.) No, I just see this as something people just aren't doing. It's much easier to just let users control all their keys instead of lying to them.


Your more fake than your reddit accounts : http://www.reddit.com/r/Bitcoin/comments/29fdhu/greenaddress_is_using_peddlers_to_hide_bad/

 I would recommend if you have any coins in here you do what I did.

 PULL THEM OUT


 This guy is pulling an elaborate scam, and the service holds your keys!

Greenaddress IS a multisig wallet.
Why are there so much trolls? ???

FrozenBit, why don't you have an SSL? Registration isn't working either.

Anyone have any thoughts on the security of this service?

Hmm look good.

You have no idea what you are talking about do you, in all of your posts round this site you are just casually giving people bad advice in every thread I see you posting in. Sorry, but someone had to say it.

For example your moronic thread about making cold storage which involved making a paper wallet at blockchain.info  :o I don't know how some people can try and advise other people when they don't know what they are talking about.

Here, you are asking where are multisig wallets, IN A THREAD SPECIFICALLY DEDICATED TO A MULTISIG WALLET! I don't think it gets any more dumb than that, unless you really are a troll, but I don't believe you are...

How do you think Greednaddress.it are stealing your private key? This I am interested to know.

Well said, put this guy on ignore.

Hi tryexcept, I have a couple of suggestions re 2fa I'm hoping you can consider.

The one thing that's keeping Google Authenticator a bit unsafe is that the same code can be reused (if it's within the same 30s window). This is something that could be abused by malware, and one of per-tx-2fa's biggest draws for me is safety from malware. I'm wondering if an option could be added to prevent the reuse of GA codes? I understand that some users would prefer not to have a once-per-30s rate limit, hence making it optional might be better than forcing it on everyone (although for myself the rate limit wouldn't bother me).

Second, how about an OTP option for 2fa? For example, I enable OTP as a 2fa method, and then ask GreenAddress to generate two or three OTPs which I store on Post-Its. I enable Google Authenticator, but I don't enable any of the other 2fa options because I consider them less secure. Now I've got a few OTPs that I can use to disable 2fa (or for any other 2fa-required action) if at some point in the future I lose my Google Authenticator, and at the same time I don't have to enable any other 2fa method.

Next, have there been any thoughts on 2fa hardware tokens, e.g. YubiKey NEO (which would work nicely with the mobile app w/o the silliness of having the second factor be on the same phone as the app)?

Lastly, how about an option to require 2fa during the initial login? The intent would be to prevent a loss of privacy in the event the mnemonic were compromised (e.g. via malware).

I look forward to your thoughts, thanks!

I don't think it should be optional, I agree that it can be safer it GA codes can't be reused not even within the window so we'll definitely make this change.


In a few words, do you want multiple GA? I don't think it makes sense to create them without asking you to confirm them. Too risky.
Or is this one GA plus some one time code to recover 2fa?

Just so that you know, we are also working on a paper 2fa, which shall contain a number of columns and rows and each with a number and a random series of these gets requested as 2fa.


Yubikey neo seems reasonable, I don' t have experiences with them but we'd have to check if they have some open API we can use and which apps to support unless it should be used with android only.

In terms of 2fa for login i would say that an option could be added for it although once they have the mnemonic the attacker can derive almost all addresess and find out information anyway.

To work around this hw wallets are best. We already support one and plan to support all major manufacturers.

Glad to hear it, this was the only major concern I had.  :)


I really should have made it clear what I was looking for, instead of suggesting some sort of solution first. I was mostly talking about a simple recovery mechanism for a lost 2fa that didn't involve email or one's phone. You're already considering a paper-based 2fa, which sounds like an even better way to address this, so that's great!


I'm not sure what an "open" API is (please excuse my ignorance), but they do publish their API online. One method they support is OATH-HOTP based (very similar to Google Authenticator, except instead of the time they use a counter which is incremented after each new code). The only reason I thought of them is because I use them with LastPass (on my desktop). I was thinking they could be both a desktop and a mobile solution, but I don't really know anything about their mobile integration (it's NFC based).


I should have realized that, thanks for correcting me. Adding such an option would only lead to a false sense of security, please pretend I had never mentioned it in the first place.  :)

For what it's worth, I've been really impressed with your overall approach. I really hope GreenAddress gets the attention it deserves!

re: YubiKey NEO

By open api i meant something we can freely integrate in our open source products.
Also, I wonder if we need to have any agreement with YubiKey before we integrate or not. I'll find out and keep you posted!

I'm very glad you like what we've done so far and that you like our plans for new features.

Feel free to spread the word/love :)

Posted a tutorial video on YouTube on how to install the GreenAddress wallet as a Chrome app from GitHub.

https://www.youtube.com/watch?v=zF3Xar5hJ_0

Installing from GitHub as per the video is useful for the following purposes:

• Avoiding the google login on the google chrome store
• Make sure you are running the open souce version
  
• Avoid autoupdates
• Play with the source code

Some feedback on the Android app:

1.) First of all, I found the app to be very slow! It stays frozen at "Logged in!" screen forever. Sometimes it will freeze at 100% when using the encrypted mnemonic and password.

2.) In my opinion, having the default login requiring the user to type in the full mnemonic is beyond tedious. Using, say, a quick login pin along with the required two-factor authentication should be the default, not simply an option. I know you guys are going for a secure wallet, but *ever* expecting a user to type in a 24 word mnemonic as the default case, especially when hitting back by accident requires typing it all in yet again, is just overkill. Copying and pasting the unencrypted mnemonic isn't safe, but having to type in such a long mnemonic conditions users into choosing such "bad" usage cases.

3.) After I created the quick login pin in settings, I hit back twice, and the app crashed. It would then crash at every loading, so I had to uninstall and re-install, and type the mnemonic in all over again. I tested doing this yet again, and it caused the same result, so this IS a reproducible bug.

4.) Having the user find out that to verify their mnemonic backup requires them to have written down their "unencrypted" mnemonic, when they weren't told this, thinking that writing down the encrypted one would be enough, is bad usability design.  

5.) You can't copy the generated mnemonic to the clipboard so as to paste it elsewhere for backup purposes, therefore you have to write it all down by hand (or, usability wise, *type* it in if you have a laptop handy, because you'll ultimately want to message it back to yourself paste it in to log in with, lolol (see number 2 above)).

The inability to copy it to the clipboard may be by design, but at least allow copying the *encrypted* mnemonic to the clipboard (and even, say, e-mailing it out, a la Mycelium's backup feature)! Go ahead and warn users of any safety concerns of this, of course. Mycelium actually has the best usability design in this area as far as I'm concerned.

And, yes, one could use the QR code option to copy the mnemonic to a second device, but just as having a laptop handy to type it in in advance of needing to copy and paste it through some messaging service back to the phone, this also requires having a second device handy, which makes things even more tedious. It'd be better to be able to go through the initialization process efficiently all on the single device, without having a pen and paper, a second phone, or a laptop next to you. If avoiding self-referential device security concerns is the issue behind why this might be by design, then tell the user that they really should have one of those three secondary items on hand at initialization -- though, the copy-paste urge still remains if the mnemonic is the default.

6.) Speaking of copy/paste usability, GreenAddress doesn't allow you to paste codes into the various numeric input boxes within the app (and though this might be by design, not all such cases are needed, for instance, with Google Authenticator codes not being pasteable, which is silly).

7.) When setting up GA, the displaying of the QR code for the seed seems utterly pointless, as anyone is going to actually want the very camera of the phone being set up to see it, not another device! Some sort of camera recursivity simply defies the laws of physics, people!

8.) By the way, GA seemed utterly broken in my case. I would copy the seed, paste it into a GA instance. This apparently didn't result in functioning code generation, as none of my resulting authenticator codes that I then typed back into GreenAddress worked. Trying to type in the GA codes, btw, with the slowness of the app's numeric keyboard causing multiple numbers to not be inputted, then finally register at once, taking so much time such that the code had expired on me, was extremely irritating. Then, once I would get it typed in correctly, it'd STILL tell me it was invalid!

mmortal03 thank you for the feedback

We have fixed some of the issues you mentioned and will release them soon in the next version on github.
Others have not been fixed yet and we'll look into them next.

Can you clarify what version of Android and mobile model you have please?

Thanks!

Thanks for working on this. I look forward to testing it.

I am using an LG Motion 4G (MS770), running Android 4.0.4 (Ice Cream Sandwich).

The ability to load the Mnemonic from NFC is not there on my phone?
It's weird because I'm sure I used it before.

Added support on both desktop and mobile (Android) for BTChip hardware wallet!

http://www.coindesk.com/btchip-launches-multi-signature-usb-bitcoin-wallet/

I figured this out.  To load from NFC just place the phone on the NFC tag from the login page.  My previous issue was that NFC wasn't working right on my phone.. I was placing the phone on the NFC tag on the greenaddress mnemonic login page, but the phone was not reading the tag  :-[.

Is NFC on ? In case it is can you try a generic NFC reader app to check if the problem is with the device or our app?

Try also rebooting the device just in case :) sometimes they get stuck.

Added support for manual fees (per tx or per kb) in advanced view.

This is very good

I just wanted to share this quick anecdote.

I've been using GreenAddress as my preferred mobile wallet for a little while now, and I've been quite happy with it.

I ran into a small issue on Friday that was preventing me from creating a transaction. It was easy to find a workaround though, so it wasn't tying me up. I did a little bit of troubleshooting, but eventually gave up.

I sent an email to their general support box on a Friday at 6pm (my local time) along with the steps to reproduce the issue, and I explicitly mentioned that it wasn't really affecting me, so it didn't matter how long it might take for a response.

To my surprise, I received a pretty detailed response back by 8am Saturday morning listing out a few different bugs (all relatively minor) that they had found and fixed, as well as an expected release timeframe for the updated version (about a week).

I just wanted to post here to commend them -- I was really impressed that they took the time to read my email and reproduce the issue, and that they got back so quickly (even though it wasn't a big deal to me). All this , and it's a free service.

So anyways, thanks for a great piece of software and a great service!

All the best,

Any way to import a private key from Blockchain.info?
I tried several times but it did not work, apparently the format is not supported.

I see that Blockchain.info is giving different options from the export function:
- Base58
- Bitcoin-Qt Format
- Base64
- Hex
- Leave Private Keys Encripted

Did you try all of them?

I also found this:
https://en.bitcoin.it/wiki/Wallet_import_format
http://gobittest.appspot.com/PrivateKey (I'm not sure that this is secure)

Maybe there are some ways to convert at least one of the blockchain.info formats to the WIF format.

I tried several ones, including screencapturing its QR-code, but none worked.
If anyone find a way plz post it.

Blockchain.info is a strictly non-BIP32 wallet (an older method of creating addresses which requires frequent backups), and with the exception of vouchers^*, GreenAddress.it is a strictly BIP32 (newer backup-friendly address creation) + multisig (much better malware protection vs. non-multisig wallets after enabling two-factor auth) wallet. There is no way to import/export between the two of them. If you'd like to switch from one to the other, you'll have to send btc from one to the other and stop using any old addresses (or continue to use both).

* Although I think you could technically create a voucher at GreenAddress and import its private keys into Blockchain.info, I have no idea why anyone would ever want to do this....

does Green address it have the saem RNG problems that blockchain.info has ?

looking at changing over with my mobile wallet

GreenAddress uses RFC 6979 (deterministic signature) on all signatures (including hardware wallet like HW1) and uses only secure RNGs. 
If a secure RNG is not available the platform is simply not supported.

All client code is open source (https://github.com/greenaddress) and feedback is welcome!

Disclaimer: I'm the founder of GreenAddress.

Sorry but any one that would be using your wallet are Noobs , why else would they not be running there own client on there own PC  :) :D

so could we please get a Noob friendly answer ?

i am confused with all the blockchain.info talk out there

There are two ways of creating a bitcoin transaction. The (generally considered older) way requires a very secure RNG (an unpredictable random number generator), and for this reason it's considered a bit more risky. This is the method that Blockchain.info uses, and a recent change inadvertently broke their RNG for a little while.

The other way is what tryexcept mentioned -- it doesn't need any RNG for creating a transaction, and is generally considered safer (although since it's also newer, not every wallet uses it). It's also much easier to write tests for, if the developers use an automated testing tool to make sure that no bugs creep in.

(There are other ways too, but they're worse than the methods above, so they're rarely used.)

(You do still need a good RNG when you first create your wallet though.)

So not been bias - greenaddress.it would be a safer option then say blockchain.info
As a mobile wallet ?

I am guessing nothing is 100% but ATM green doesn't have any known flaws ?

Technology-wise, they check off a number of boxes which Blockchain.info misses.

I don't think they have any black marks in their history (BC.i has a number of them), but they're also much younger than BC.i. Short of an independent audit... it's awfully hard to say.

Having said that, they are the mobile wall that I've chosen to use, so I at least think that they're a safe option.

If you do go with them, please be certain to:

• Write down your "mnemonic" as soon as you can. It's your backup, your password (PIN) recovery, and it's the only way you can log into your wallet from new devices. Don't save it to your PC (or learn how to use strong encryption if you must).
• Don't be afraid of using the PIN quick login option, it may seem like weak security but it's actually quite strong (and convenient). (If you enter your PIN in wrong just 3 times, it becomes useless and you'll need your mnemonic which you wrote down earlier.)
• Enable email notification for both inbound and outbound notifications. Each email notification contains a special recovery file which you'll need should GreenAddress ever disappear from the net (heaven forbid, of course).
• If you intend on using GreenAddress from a desktop, enable two-factor authentication. For a mobile, I'd be less concerned about two-factor.

That's my 2 satoshis...

New Android app coming!

Click to see a short demonstration with a (optional) Trezor!

https://i.imgur.com/au39C28.png (https://www.youtube.com/watch?v=GmzIBCliiWI&feature=youtu.be)


Want to try it now?

The app is actually available in early Beta for both Testnet and Mainet on a G+ community (requires to join the community to download the app)

G+ community https://plus.google.com/communities/114049784968466332392

Testnet https://play.google.com/apps/testing/com.greenaddress.greenbits_android_wallet.testnet

Prod https://play.google.com/apps/testing/com.greenaddress.greenbits_android_wallet

All feedback and feature requests are welcome!

The android app looks sweet, can't wait to try it out!

This new one is very user-friendly :)

Not working for me.

I started with a blank Trezor,  upgraded to 1.3.0 firmware and everything was working well using desktop chrome + the chrome extension.  I was able to generate a 24 word seed on trezor and login.

Using the same trezor on a Note 4, the trezor is detected and I was able to login to the desktop chrome extension wallet

When I plug in the trezor to my note 4 via OTG, the Greenbit (mainnet) app does pop up and ask's me to follow the commands on Trezor's screen and greenbit fades away after 1-2 seconds.

Unplug/replug doesn't help. Only the lockscreen on Trezor. 

Wiping Trezor and starting blank, has the same problem.

On a lighter note, HW1 plus desktop chrome extension works well, and this sane HW1 works with android wallet Cordova. The android app can't seem to initialize a blank HW1 like the desktop extension can.

Great. I will test it out soon.

So this is the official application from Greenaddress?

Thanks in advance!

Kind regards

Correct, only the desktop app can currently initialize an HW.1 or Ledger or Trezor for that matter.
In the future the functionality will be added to the mobile apps too.

I'm not sure why it doesn't work with the Note 4.
As you know GreenBits is still in Beta and Trezor support is very recent but we tested the functionality on both a Nexus 5 and a Galaxy S5 so far and it works for both Mainnet and Testnet.

One thing to notice is that currently if you try to access your wallet with a Trezor but on the wrong network, i.e. use a testnet seed on prod or viceversa, then the app currently doesn't show an error, just redirects to the first screen where you can create a new wallet or access your existing one. I take this is not what you are seeing as you spoke clearly about mainnet.

We'll try on more devices but one thing to keep in mind is that this is not something we can test with the Android emulator as far as I know and obviously we don't have all Android devices at disposal.

It would help if you could provide an adb logcat trace, to see if anything that goes wrong is visible in the logs.

 If this is too much to ask we understand, after all normally people don't have adb or Android tools installed on their computer :)

I have a feeling I know what it could be, I'll test on a Nexus 7 today to see if it has to do with larger layouts in which case we should be able to fix this quickly.

Thanks for trying it!


Not yet but it will be eventually. Currently the new app, called GreenBits, is still in Beta and does not support all features offered by our other GreenAddress app for Android but it is already much better for a snappier user experience on the go.

Small update, we tested with a Nexus 7 and it worked fine.

I'll give an update if I get hold of Note 4, meanwhile if anyone with a Note 4 can try and provide adb logcat it would be great!

Another update: I found a way to test it in the emulator via virtualbox with USB pass through support.

The emulator doesn't have the Note 4.0 but it does have Note 3 with 4.4.4 and it worked fine (We tried both horizontal and vertical orientation so it wasn't that).

wow , I was playing around and found that the mobile app is the only wallet that can sweep BTC from paper wallet
coinjar, coinbase , blockchain dont have this option on the mobile apps :)

Mycelium can.

Impressive work with this wallet tbh! I wrote an article about it, which you can see here :

http://www.cryptoarticles.com/crypto-news/greenaddress-cross-platform-multi-signature-bitcoin-wallet-with-improved-security-privacy

Hope you like it :)

Didnt know they had a ios app ? i havent try it yet

Mycelim hasn't released an iOS app^[1]. They told, if someone could do it, they will give full support.

I used GreenAddress for BTChip. It was pretty easy and great one. :)

Edit: [1] See below post. :)

Thanks for the heads up. :) Corrected my post. I tried to import private key but it keeps saying "error loading coins" or similar. ???

   ~~MZ~~

I am still pretty happy with green . Does every thing you could ask a wallet

Wish the SMS was faster ( take me 40 min in Australia for 2fa ) would be great if they had the same set up like blockchain with SMS DESPOIST And withdraws - email is a good but SMS is better)

I wonder when they will included the paid account options later

This looks really good  ;)

Has anyone tried using the open source chrome wallet code and modifying it for an alt coin?

I'm going to move away from this wallet!
It's third time than I cannot send money. I'm always receiving some error messages from server.
For me, it's not a good sign to have no ability to use the money.
Last time the issue was for three days.

P.S. Customer support is not answering.

Newbie with 1 post. You are probably trying to make it bad. There was no reports here AFAIK. It maybe some sort of mistake by your side. :)

   ~~MZ~~

It is Sunday so customer services may take a few hours to get back to emails  ::)

We replied to the user privately via email (assuming it is the same user) and asked to provide more information (which app, what version, which device, etc) as we can't reproduce the issue.

is there a problem with greenaddress, cannot send BTC

Request time out ( vault/prepare_tx )

Barzoks, could you contact support at info@greenaddress.it ?

meanwhile we'll investigate with what we have

thanks

Done sir
email sent

I got same problem like this

GreenBits (https://play.google.com/store/apps/details?id=com.greenaddress.greenbits_android_wallet)

GreenAddress and its team are happy to announce the availability of GreenBits (https://play.google.com/store/apps/details?id=com.greenaddress.greenbits_android_wallet) in the Android Play (https://play.google.com/store/apps/details?id=com.greenaddress.greenbits_android_wallet) and Fdroid (https://f-droid.org/repository/browse/?fdfilter=greenaddress&fdid=com.greenaddress.greenbits_android_wallet) open source stores.

A new, open source (https://github.com/greenaddress/GreenBits), snappy Android Bitcoin Wallet combining the improved security provided by multisignature and hardware wallets to enhance both security and user experience.

Based on BitcoinJ (https://bitcoinj.github.io/), the app supports all hardware wallets currently available including the Ledger Nano (https://www.ledgerwallet.com/r/bead) and HW.1 (https://hardwarewallet.com/) as well as Satoshilabs’ TREZOR (https://github.com/trezor/) and clones such as BWALLET (http://www.reddit.com/r/Bitcoin/comments/2t8ppe/now_you_can_buy_a_trezorlike_hardware_wallet_in/).

The app supports the following functionality:

• Hardware wallet support: Ledger’s Nano and Satoshilabs’ TREZOR (and clones)
• Payment protocol aka BIP70 via clickable links, QrCode or NFC
• HD/BIP32: deterministic and doesn’t reuse Bitcoin addresses
• 4 or more digits PIN (with server assisted strong 256 bit AES random key) to protect against brute force attacks while providing a smooth user experience
• 2of2 and 2of3 sub accounts to separate funds
• Instant confirmation with supported parties, ideal for recipient double spend protection
• All bitcoin denominations (BTC, mBTC, uBTC _and_ Bits)
• Spending Limits in BTC or fiat terms
• 4 different kinds of 2FA authentication (SMS, Email, OTP and robot call)
• Sweeping paper wallets
• The large majority of price sources in various currencies
• Early support for Proton, Ledger’s NFC Bitcoin Wallet prototype

The app is available for both MainNet (https://play.google.com/store/apps/details?id=com.greenaddress.greenbits_android_wallet) and TestNet (https://play.google.com/store/apps/details?id=com.greenaddress.greenbits_android_wallet.testnet), some functionality currently requires use of the  GreenAddress desktop app (https://chrome.google.com/webstore/detail/dgbimgjoijjemhdamicmljbncacfndmp) to be used (for instance enabling/disabling 2FA, Limits, initializing hardware wallets, etc).

Some have asked why we have a new app and what will happen to the old Android app we have.

While the old app provided a great amount of functionality we came to the conclusion that having a native Android app provides a better user experience and generally faster payments.

We will keep both for the time being as GreenBits becomes more robust and supports all features GreenAddress has.

I'm testing the Android app on an Azpen A729 tablet (Android version 4.4.2). The Trezor is detected and GreenBits loads, saying onscreen "Please follow the instructions on your Trezor", but the Trezor just remains on the My Trezor "lock" screen and doesn't do anything.

did you first initialize the Trezor with GreenAddress on the desktop app?

It should notify you if it hasn't been paired yet but that could be why it doesn't work.

Nope, I didn't realize that that was a necessary step, but, like you said, it didn't notify me of this, either, so it should! :) I'll try initializing it.

Ok, now we've got a problem. The process of creating a wallet on the Desktop app along with a Trezor is *very* confusing. While I'm knowledgeable about bitcoin wallets, I'm completely new to how the Trezor is supposed to work with GreenAddress, so I must not be following the steps properly. I thought that this feature was another way to use my already existing Trezor account from within GreenAddress. Instead, this seems to be some sort of feature to store an existing GreenAddress account on a Trezor? Or what? I obviously am not doing this correctly at all!

What happened the first time was that I didn't copy down the mnemonic when creating the account with it on GreenAddress, because I thought that the Trezor would be acting in this capacity, in other words, I thought that GreenAddress would be reading in the Trezor account that I already have stored on the Trezor.

The on screen instructions were confusing. The instructions asked me to check whether my passphrase was saved and secured, but *no* passphrase was shown for me to write down! This, again, had me assuming that the Trezor would be handling this. So, I just checked the box and moved on to the next step.

You might ask, Why didn't I scan the QR code? I obviously didn't think that I needed to. Usability advice for you guys: Please display the passphrase in plaintext for the user to write down right then and there (if that is the case when using the Trezor), or at least make it explicit to users that they need to scan the QR Code representing the passphrase. Users just aren't going to understand that the QR Code *is* the passphrase (the "Show QR Code" button should actually *explicitly* say "Show QR Code containing passphrase" so that the user understands this).

Anyway, now I don't have my passphrase that I created when I first linked it to my Trezor, and now I can't log in to GreenAddress with my Trezor, nor can I create a new GreenAddress wallet that seems to be associated with my Trezor in any way. Maybe not having the first passphrase has nothing to do with this, and it's something else going on, but here's what's happening:

When I click the "Trezor login" button, I then press the right button on the Trezor to confirm, then I enter my Trezor key into GreenAddress by clicking on the question marks, and then I get either "An error occurred that forced us to log you out". or "Login failed, account not found. Please create a new account with your Trezor."

When I do try to create a new wallet in GreenAddress with the Trezor attached, I *can* later paste in the passphrase from subsequent QR codes that GreenAddress creates and log in, no problem, but that works whether or not the Trezor is attached, so that just seems like a regular GreenAddress wallet, and nothing to do with the Trezor.

You didn't pair your Trezor, I think you just created a new GreenAddress wallet.

GreenAddress is a multisig oracle and all wallets you can create with it are either 2of2 or 2of3 (subwallets)

The pairing requires some better instructions.

Anyhow, when creating a new account you can choose if you want to generate a new set of mnemonics (what I think you did) or if you want to use the seed already on your harware wallet (there's a button inside the mnemonic box to do that)

Once that is done you can use the Trezor with GreenBits.

Please note that you can't use your trezor with GreenAddress as a direct 1to1 replacement of myTrezor as we do not support the same wallet format (BIP44) and addresses generated by GreenAddress/GreenBits are multisignature.

When is this done? Do I create a standard GreenAddress wallet, and then pair it in the settings or something?

Creating it on the front end isn't clear at all.


I have not seen this option. Can you provide a screenshot of this screen?


Are you saying that GreenAddress includes additional functionality that isn't present in myTrezor, or that something is missing from GreenAddress that is in myTrezor?

Any GreenAddress wallet is automatically paired with GreenAddress in multisig.

What I'm trying to say is that if you want to use your Trezor seed instead of a new set of mnemonics you can by clicking a button during onboarding/signup/registration.

See https://i.imgur.com/V3sgwMO.png


Both. GreenAddress includes additional functionality not present in myTrezor (multisig, per transaction 2FA, limits, etc) and that it does not share the same wallet structure as myTrezor.

That is to say that if you use the same seed on both services you won't be seeing the same transactions or funds. I usually advice people to use different seeds for different services (it helps with your privacy at the very least)

That just takes me to the "Use TREZOR to create a GreenAddress wallet" screen that I've already been at, which doesn't work after setting it up.
 


Okay, this isn't a primary concern, but, is there a way to have both, while using the same Trezor device? (in other words, have a Trezor account representing one seed that is used with myTrezor, and another, empty account on myTrezor that is used as the seed for GreenAddress?

are you using the chrome app?

I think trezor supports only one seed but you could use different pass phrases for the same seed

Yes.

"You need to wait for previous transactions to get at least 1 confirmations"


Why is this limitation if i want to start another transaction/sending ?

If you send/receive a transaction and somehow, it was dropped from the Blockchain. Then, the transaction you send will be like invalid because the TX hash of your input(s) will be invalid as the TX isn't existing in Blockchain. I hope you understand. :)

P.S. AFAIK all wallets have this restriction/limitation.

   -MZ

Cool concept.  I think I will give this one a go.  :)

 Until 20th Feb  , the fee was the usual  0.1  but now it is 0.16621    (for me)
it is 66 % increase   , why?    if i make 10 transactions daily , my monthly fee will be $12 , is this normal ?

lol

Amount
    1,900.00 mBTC

Fee
    0.42434 mBTC

it is time to fill the Fee field by yourself with the default 0.1 mBTC  or you will have to pay more and more fees if you allow greenaddress to set your transaction fees
(It took 5 minutes for the first confirmation  with 0.1 mBTC fee , so i cant understand why greenaddress want me (and others) to pay 4 times more than the earlier fee)

It would be great if there were an option  in the settings  for default transaction fee.
Because now it is very annoying that i have to set it always to 0.1

Hi GreenAddress People:

I'm posting this here just 'cuz I'm not sure where it should go... already tried emailing for support (over a week ago) but got no reply as of yet, so...  ::)

Topic is: I am having a problem with the GoogleAuth 2FA on my GreenAddress wallet/account.  GAuth is working fine for other sites I use it with (LBC, BC.INFO, etc) so it's not likely a time-sync issue.

Obviously the QRCode for my GreenAddress wallet *SHOULD BE* okay since it worked at first, i.e. when I first set it up!

But it's now stopped working, for some reason.

Any time I enter the GAuth code for anything in GreenAddress all I get is the "code is wrong" error.  I've tried it on the website based wallet, on my iPhone using the app, and even using the GoogleChrome standalone app. Same problem each time.  GAuth just not recognized as correct, ever, anywhere.  Just ain't working.

So I then tried turning OFF the 2FA entirely, but doing that requires a GoogleAuth code!  So, duh, that's not gonna work either.

At the moment I have only about $20-$30 worth of bitcoin in my GreenAddress wallet (was just using it to test out how GreenAddress works, before committing more funds to it perhaps) but those bitcoin are now essentially locked away from me, can't MOVE anything without the 2FA code.

I *do* still have my mnenomic for the wallet, so hopefully that means that I can, somehow, still get the bitcoin out of this wallet, if the 2FA problem/issue cannot be resolved?  How would I go about doing that, exactly?

Again, sorry if this is posted in the wrong place or should be on it's own topic here... moderators please feel free to move topic if so.

TIA for any/all help anyone can provide.

Hmm... the one time I emailed them, they got back to me the next morning....


I'm not sure what the technical issue might be. FWIW it's working for me at the moment.


The whole point of 2FA w/multisig wallets is that you can't access them without your 2FA... if there was a simple recovery procedure, that'd mostly defeat the purpose. I take it you only set up one 2FA method, with no backup method?

Did you ever add an email address to your GA account (you can't add one now because it requires a 2FA code)? If so, it is possible to regain access to your funds even w/o GA's help but there will be a pretty long delay (probably around 90 days). Let me know and I'll point you towards the directions to do this, in case GA doesn't get back to you.

Hi,

Google auth works for our accounts too. if it works for other sites it may mean they have a more relaxed timeout while GreenAddress only allows the codes in the window shown in the authenticator app.

this is to say that this points to a tiny synchronization issue that usually is fixed by a resync of the app (sometimes a full restart of the phone seems necessary)

let us know if this fixes it and if not we can try to work out something.

some users have found a way by using codes after they expire (which assumes the phone has the clock slightly ahead)

Hi, thanks for replies.

I tried the "enter GAuth code after time expired" trick... but no go.  Didn't work, still just says invalid code.

This wallet DOES have my email associated with it, so that's good news, I suppose?  What can be done at GA's end with this info?  Maybe manually turn on email 2FA or something??

The main problem here, I suppose, is that the ONLY setting enabled for this wallet's 2FA at the moment is Google Authenticator.  And since GA saw fit to stop working for whatever reason, I'm locked out prevented from doing anything.

Earlier, I had the voice phone option enabled at first (before GAuth) but I found it annoying so I turned it off.  So the only 2FA enabled now is JUST Google... clearly in hindsight my main mistake here I guess is not keeping a second 2FA choice turned ON, but for some reason I was thinking there had to be only one at a time enabled.

Might be a good idea in the GreenAddress UI to make a note that "more is better" (?) to prevent others in the future from making this mistake?

So... next step here? HOW to get some other 2FA going somehow, so I can turn OFF and/or re-install or re-initialize GoogleAuth???

As far as I know there's nothing wrong with you Google Authenticator seed and assuming your phone didn't flip some bits internally you just need to synchronize your phone properly.

It happens often that Google Authenticator goes out of sync.

We can't just enable any other 2FA ourselves. With the email what you can do is unlock the funds yourself when the timelock expires, which is by default 90 days from your last transaction unless you have changed this value. This is by using a zip attached to the emails and a tool called Gentle you can use with Firefox.

I would not concentrate on this option just yet as I am pretty sure a resync to Google Authenticator will do the trick, it is always this in the end when it doesn't work properly.

It is... it means it is possible (although a small bit painful) to recover your funds, even in the worst case.


tryexcept is a GA employee, I'd wait for his response, perhaps he can help. (edited: oops, looks like he beat me to the punch)


I agree, if someone enables only a single 2FA method that offers no recovery option, it would be nice to warn them of potential issues.

I just installed the Chrome app and I've got to say I love the wallet. Great work!

Hi Folks:

Okay I'm back here to this thread, and over the last week or so I've tried *everything* I can, based on info above, to get my GreenAddress wallet working again.

But nothing I do works, the GoogleAuth 2FA simply just always says invalid.

I've tried rebooting my iPhone, I'm even using another instance of Google Auth via the Chrome applet (and both iPhone and applet are giving the same codes, simultaneously, on totally different hardware: so that would SEEM to indicate that everything is sync'ed up correctly, right?)

I could've sworn that I had it working *at first* though... I saved the QR code and text info and checking that against my GAuth setup appears to be okay.  And ALL OTHER instances of GoogleAuth I'm using everywhere else, like on my blockchain.info wallet and for localbitcoins etc, are ALL working fine!

So, WHAT could have gone wrong here, really? What am I missing?

Anyway, if the GoogleAuth thing can't be fixed somehow, what's next?

Do I have to wait for the 90 days time-out and get the coin out of this wallet that way? That'll be around end of June or early July I guess.

How exactly do I do that?  OR would it be better to wait until then and address it in another forum topic?

TIA for all help.

No bright ideas from me....

The only other troubleshooting step I can think of would be to extract the shared secret from Google Auth, and check to see if it matches the shared secret on GA's side. Doing so would require your phone be rooted, and would require some work on your part (and on GA's).


First step: log in, go to Settings -> Security, and click the "Send all nLockTime transactions by email", and save the nlocktimes.zip file you receive via email in a safe place (and be sure to keep your mnemonic around somewhere too, it'll also be required later).

Second step: figure out when you can perform the recovery. Use a block explorer to determine the date and the tx height (in blocks) of your most recent tx (inbound or outbound). Assuming you haven't changed the defaults, add 12960 to this tx height, and add 90 days to the date. Set a reminder on your calendar for this +90 days date.

Step three: visit here: http://greenaddress.github.io/gentle/ (http://greenaddress.github.io/gentle/), and do a "File -> Save as" to save the web page recovery tool to your PC. Keep it along side the file you saved from the first step.

Step four: Wait.... when your reminder date comes nears, check the block height of the most recent block at your favorite block explorer, and if it exceeds the the height you recorded in step two, open the page you saved in step three and follow the instructions. You'll need your full mnemonic at this point as well.

The recovery page only works with Firefox and Chrome (but see here (https://github.com/greenaddress/gentle/issues/2) to work around a problem when using it with Chrome). I've tested this procedure once in the past, and had no trouble getting it to work (except for the Chrome issue I just mentioned).

OK, thanks.

I got the emailed ZIP file... not really sure yet what that enclosed "nlocktimes.encrypted" file is for, but I suppose it'll become clearer later.

Anyway, last transaction was on 03-17-2015 so gotta wait till about mid-June to proceed here I guess... at least it's only about $35 worth of bitcoin stuck there, good thing I didn't move more into GreenAddress until I've thoroughly learned/understand all of this stuff.

BTW I should say I do like the GreenAddress wallet overall, it's just pretty clear that users need to be fully informed of the pitfalls and hazards of this more ADVANCED encryption and wallet protection technology, before using it seriously. "Being Your Own Bank" with bitcoin means nobody else can fix it for you if YOU screw it up (like I did, by not having a second 2FA option enabled).

So, hopefully my messing this up here and talking about it on the forum might help others avoid problems: my pain is your gain LOL

I'll be back after about 6-17 to continue this saga, Stay Tuned  :P

I never got my Trezor to pair with the Chrome app. tryexcept was helping me, starting here (but we never solved the problem): https://bitcointalk.org/index.php?topic=521988.msg10398518#msg10398518

Question: Do you have to wipe the Trezor to use it with GreenAddress? I already have a regular Trezor wallet on there. Maybe that is the problem? I see that there is the option to clone a GreenAddress wallet to a hardware device, but it has to wipe the device to do so.

thx  for do nothing

When i add a new entry to the address book and want to use it at the send money tab I almost always got an error:  "Invalid recipient address."  (I have to select it many times before your system will accept it after send money button click )
Please fix it.

If somebody has 2 or more greenaddress wallets then he has to clear the browser history (cookies, etc.)  to be able to login to another wallet, because at login page you can only enter your pin number and there is no button to forget current wallet data. (login with another account/wallet)

Do you not have a "Show other logins" option just below the PIN field?

https://i.imgur.com/HdhM6hI.png (http://imgur.com/HdhM6hI)

Ok, it works, but if i login with my other wallet (with passphrase) and logout and login again (with pin number, same pin) then i will be logged in into my 1st wallet and not into my 2nd wallet that i used the last time.

Sounds to me like that might be a bug....

Just a suggestion: if you're only using different accounts for keeping funds separate, it might make more sense to use the built-in multiple accounts feature (near the bottom of the settings page).

is the bug confirmed / fixed?

I have the app GreenBits installed on my Android phone.

When I try to sweep a Wallet after scanning the private keys the following message is displayed:
"Not Enough Money"

The wallet has 0.5$ in BTC
Isn't that enough to sweep the funds?

I'm having trouble accessing my funds in the GreenBits app and can't login on the website either (it just keeps saying that I'm already logged in (https://i.imgur.com/ORH2Uz5.png) - maybe my phone didn't log out correctly?)

I'm using the LG Nexus 5 with a TREZOR.

OK, I am BACK.

I got an emailed notice yesterday that said:

>>>Some of your deposits will soon expire because of nLockTime.
>>>
>>>Please log in at https://greenaddress.it/wallet/ to re-deposit them.

...which I assume is related to my problem (above) of having screwed up my 2FA/GoogleAuth setup in my GreenAddress wallet.

So: what do I need to do here? 

I want to either get the small amount of bitcoin OUT of that wallet, moved into a new GreenAddress wallet I will set up again from scratch (hopefully not goofing up the 2FA this time) -OR- just somehow re-set the existing wallet again (turn off 2FA?) so I can use it... what's the best way to go here?

Please "ELI5" to a noob (me) as simple as possible LOL

nLockTime transactions will have a pre-set period of time and deposits 'expire' when the period is up. It is enabled by default when you have email notifications and two factor enabled. Every time the funds expire the user has to re-transfer them. This can be automated on login and notified in advance via email or manually done.

GreenAddress will send a transaction with nLockTime whenever a deposit is made. This transaction sends the funds back to the depositor. The nLockTime transaction will have expiry and after this time, it will be included in a block and the user who deposited will get the funds back.

For redeeming the funds after expiration, you can use https://gentle.greenaddress.it/. You can download this webpage from https://github.com/greenaddress/gentle so that if the website goes down, you can still redeem funds.

Always keep your nLockTime transaction safely.

Hi Muhammed: okay thanks for that, but gotta say it's still pretty much going over my head LOL

No idea what's really goin' on here... I feel like I'm pretty up to speed on bitcoin in general BUT this advanced stuff is still not really GELLING so fast.  Bitcoin still has a long way to go before the average man on the street is gonna be able to handle it.

Anyway, okay, I just blindly forged ahead here and went to that "gentle" website, using my mnenomic and the ZIP file.

Entering those, it chewed on it for a bit and then presented me a page showing two private keys, with a check box and a button for if I wanted to PUSH the listed transactions.

Now, not really knowing what else I could do I figured, (insert Hunter S. Thompson voice impression here) "okay, why not?"

Pushed them, copied private keys into a new "import" wallet using the (more simple and relatively easy to understand, for me) blockchain.info wallet service... and now the bitcoin seems to have been (mostly?) moved to this blockchain wallet.

Less a little dust, apparently, for fees and whatnot... not exactly the balance that I thought I had there but so far so good.

SO... bottom line?  Funds recovered and sent back to my main working address.  All good.

I want to now TRY AGAIN and set up a new GreenAddress wallet (delete all traces of the old damaged one from my system, desktop PC and iPhone app both)... hopefully not goofing up the 2FA settings this time.

How should I best go about doing that, next?

TIA for all comments :)

I'm glad you finally worked everything out!

It's possible that some of your deposits have not yet expired, even if most of your larger ones have. If there are still funds left in your old wallet, you may want to try this process again in another week or two to recover the remaining funds (if any).


It should be pretty straight-forward. On one of your devices, launch the app and choose "Create new Wallet" in the upper right corner. On your other devices (if any), click the slider at the bottom labeled "Show other logins", and use your full mnemonic (from step one) to log in.

Since the app only keeps track of the most recently used wallet, there's no need to do any wallet deleting.

FYI when you set up 2FA, I think you might need to use a separate email address, not sure though.... (And of course this goes without saying: give them an email address and enable notifications just like you did last time in case you need to do an account recovery again ;))

Me too.
I cannot login more than 6 hours.

"You are already logged in. Do you want to log out the other session?"

There is no other session. I restarted my PC and tried to login with 3 different browsers too.  

I always got the same error message.

I have 2 wallets, I can login with the another one.  So it is very interesting.

The wallet i cannot login has no 2 factor authentication and perhaps i did not give any email address at the wallet creation time . (so there is no nlocktime files) .
(As i see 2 factor authentication is now required to create  a new wallet)

I hope greenaddress could fix this bug or they will owe me 60 bitcoins.

Nope... all cleared out to -zero-

There were only TWO transactions sending small amounts of bitcoin IN to this wallet (just to test how it worked) before I realized that I had screwed up the 2FA settings and could not get any funds OUT of it, so PUSHING only these two (as noted above) were all that could've been possible.


Okay I see that, but I also saw the "delete all info from our servers" button inside the wallet, which I would've LIKED to be able to do just to be very thorough and make it impossible to use this wallet again in the future, even by mistake.

But, AAAGGGG, that function *ALSO* required the use of the corrupted 2FA GoogleAuth to proceed!!  So it too is "blocked".  :(


Fortunately, it appears that the SAME email I used on the bad wallet IS allowed to be used again for a NEW wallet, and cell phone number etc too.

I have now set up a new GreenAddress wallet with all the same info as the corrupted wallet, same address book entries I made before and etc, and the only thing that seems to be different is the mnemonic passphrase for logging in to them.

So, in theory, I suppose it IS still possible for me to use the wrong "old" mnemonic and log in again to the corrupted wallet, but that probably won't happen in practice, as long as the GreenAddress software only always uses the most recent wallet opened via the PIN entry.

So, all in all... everything's fixed I think.

It took 90 days, but no funds lost (if you don't count the decline in bitcoin exchange rate value during that waiting time, LOL)

Thanks again to everyone for help :)

Now it works again. I hope greenaddress fixed it or it can happen anytime again ...

Me too.

I also hope you've added an email address, enabled both send & receive notifications, and written down your mnemonic so that you won't have to worry about losing your funds....

Website down and unable to log in to chrome extension for a couple of hours what's up?  ???

using the same pin# for 2 wallets does not sound like a good idea to me

Same problem here, can't access my coins, absolutely no response from support.

10 hours later and i am still sitting here trying to log in. WTF IS GOING ON GREENADDRESS ANSWER ME! I NEED MY COINS.

Hello Everyone!

I just set up the Chrome version of GreenAddress on my laptop. It looks really nice!

But I'm a little confused. I set up up a MultiSig sub-wallet and have backed up the recovery information and the xpub key as suggested/warned. But what do I do at this point? How do I use it? Can it be used with something like a Blockchain.info wallet? Is there any documentation that can walk me through the process of getting a GreenAddress MultiSig wallet actually operating?

I don't know if I'm being thick-headed or what but I just don't see how to implement the wallet now that I've created it.

Please advise.

I think you can use Electrum^[1]. I have not tried it. You will have to choose 2-of-3 when creating Electrum wallet.

FYI -- xpub key is extended public key which you can use to check your balance in block explorers.

[1] https://github.com/greenaddress/electrum/tree/greenaddress-2of3-recovery

Thanks for the response but it doesn't address my question. I'm looking for a step-by-step guide on how to implement and use Multi-Sig.

Here is what we've tried so far:

1. I created an multisig wallet using GreenAddress. I backed up the pass phrase as well as the xpub hey.

2. I had my friend create a multisig wallet using GreenAddress but this time when he created his wallet he did it using the xpub key I supplied him.

3. I put $0.10 into the newly created multisig wallet.

Now here is where things fall apart. I see the $0.10 in the new wallet with confirmations. When my friend starts GreenAddress although the multisig wallet is there it has a zero balance.  The $0.10 deposit is not reflected in his wallet.

So I'm thinking we did something wrong in the wallet creation or we missed a step at some point? So you see what my question is now? We're looking for some guidance/documentation/inspiration on how to correctly setup, implement, and use a multisig wallet using Greenaddress.

I looked at the Electrum wiki and it really didn't explain things. I don't want to use Electrum (although I like it) because I'm using a HW.1 hardware wallet in conjunction with GreenAddress. I know the docs state that Electrum supports the HW.1 but I'm on Windows 7 and Electrum doesn't appear to support the HW.1 without a bunch of additional libraries and a re-compile from source. I'm not a programmer and I don't have the ability to build Electrum from source.

There are sites out there on the web that discuss multisig and there are Youtube videos. But so far I haven't found anything on how to actually implement multisig.

I'm still very confused about the MultiSig wallet.

After creating a multisig wallet using the Chrome app I sent a test amount to another address but was never prompted for any additional verification or
request for any additional signatures outside of the 2FA challenge.

Can you please explain the difference between the standard wallet and the multisig wallet? I just don't see any difference.

Thank you in advance.

GreenAddress is 2 of 2 multisig, both keys are required to spend, and you can specify the criteria under which GreenAddress will cosign with their key. You can set spending limits, 2nd factor confirmation, etc

Thanks for answering. But again, I don't mean to be rude, but I read that on their webpage too. My original question still remains. How do I implement MultiSig using GreenAddress? I don't see any functional difference between 2of2 and 2of3. How do you utilize 2of3?

So far I've tried to ask this question at least 3 different times in 3 different ways. Am I just asking in the wrong place? Is there a different forum somewhere that I should be asking my questions?

Thanks.

GA 2 of 2 multisig is not like 2 of 3 Coinkite/bitgo/coinbase/copay multisig.

You control one key, GA controls the other key, that's it.


If you spend with Greenaddress Chrome App / Android Greenaddress / Android Greenbits then you're using multisig.

Other schemes let you choose who the cosigners are by xpub, this is not how GreenAddress works.

In order to prevent loss of bitcoins if Greenaddress disappears they sign with their key an nTimeLock withdrawal transaction.

greenaddress does actually in the app have a 2 of 3 scheme, ignore it for the sake of simplicity

Thank you! That's exactly what I was looking for!!! BTW I found that the 2of3 feature in GA has value as you can add the xpub key to a 3rd party app like Electrum and then use Electrum to generate the transaction and have GA be one of "signers"

I have the desktop chrome plugin version...
It's the third time this week i come to try to access my wallet and i can't login. Is there a way to to get a desktop version that can login even when the website is down? Otherwise i don't get what's the point of a desktop/web wallet hybrid with better security if you can't access your BTC half the time?

Any one have issue with their SMS? I can't seem to get any thing from them, even creating a new account does not allow a sms verification to work.

I made a payout to my greenaddress wallet 3 hours ago .  It has 15 confirmations, but my greenaddress wallet does not show this transaction.  (I tried 2 browsers to check it)

???

Are you sure you're connected and sent to the right address and selected the right wallet? (Main, others)

(I login into this account at least 5 times a day. )

It showed up in my wallet only after 3.5 hours.  (at this time the transaction had 15 confirmations, greenaddres showed unconfirmed, 5 minutes later 1 confirmation, 10 minutes later 3 confirmation, and so on. )

This is not my first issue with greenaddress. (Last time i could not login more than 12-16 hours into one of my wallet, the other ones worked.)

I  never got any answer to my emails, customer service does not exists.

It is time to find another wallet service for me.

I stopped using GreenAddress for the exact same reason. For me it was their server going down all the time so i would lose access to my coin all the time. Now i just went back to SPV wallet, offline HD one.

You can see i posted here over one month ago and i never got a reply. Same for reddit. GreenAddress seem dead to me.

Meanwhile Multibit HD replied to me within a day. Even several time same day while we discussed an ongoing issue.

Lol  " No blocks seen for 2 hours. Transactions temporarily disabled until new blocks are seen."  
So nobody can  make any outgoing transaction, and i think this is why last time the wallet showed my incoming transaction only after 3.5 hours.

i can confirm again that greenaddress is useless.

Unconfirmed transaction more than 18 hours

When will i get back this 2 BTC or when will be this transaction confirmed?

Hi,

Is this an incoming transactions or outgoing?

Looks like it was never confirmed nor I can find it in mempool.

Perhaps this has been caused by the malleability attack?

Outgoing

I do not know.  I sent it 18 hours ago.

May a create new addresses?  (Or try to make any new incoming or outgoing transactions? )

Help plz.
today cant doing transaction all time write INTERNAL ERROR
when i logining into my account them write You have some expired deposit.Unless u redepost or reedem them,instant confirmation transaction will not be allowed.I push to redeposit and it write me INTERNAL ERROR Help plz!
http://f-picture.net/lfp/s010.radikal.ru/i313/1510/8f/41d0070af097.jpg/htm

same to me

+ When i try to start an outgoing transaction i got an internal error also.  (So i cannot made any outgoing transaction)
There is also a lot of new address that i have never created.  (I did not click on the "Show URI and address" button so many times  )

DO NOT USE GREENADDRESS.

MY 40 BTC IS LOCKED AND THERE IS NO SUPPORT.

YOU CAN LOSE ALL YOUR FUNDS.  IT IS POSSIBLE THAT I HAVE ALREADY LOST 40 BTC.

FAQ:
"nLockTime transactions which essentially make deposits 'expire' after some time,"
"It also means that every time the funds expire the user HAS TO re-transfer them."  

When i login i got this message:
"You have some expired deposits. Unless you re-deposit or redeem them, Instant Confirmation transactions will not be allowed"

but redeposit does not work and i cannot make any outgoing transaction. (I got internal error all time)

Now i am going to create new reddit/facebook/twitter accounts and share all these issues on (the pages of) greenaddress.
I will also take legal actions againt greenaddress if my 40 BTC is lost.

bgerg, we are working on it and we are sorry it takes longer than we wished.

You can show your disappointment on our facebook page or twitter but it won't make us faster and instead it may slow us down a bit.

If you don't want to wait you don't have to, you can use the Gentle tool https://greenaddress.github.io/gentle/ - it is designed for situations where GreenAddress is not available to recover the funds or anyhow for independent recovery.

To reduce your wait from 90 days default to 1 day you need to first go to your GreenAddress wallet settings and set an nlocktime of 144 blocks, then enable email notification if you haven't done so yet and within 24 hours you can take your bitcoin independently of GreenAddress.

By default this is set to 90 days but you can change this as per these instructions.

Once you receive the email with an attached zip you can wait for 144 blocks (24 hours) and then open the Gentle tool in firefox and with your zip files and mnemonics you can export private keys to be swept anywhere in the Wallet Import Format (WIF) standard by any wallet you want.

Hope this helps and I want to reassure that we are going to fix this as soon as possible.

I also hung a large amount of money why do not you answer me?
I USE GENTLE!BUT THEM DONT WORK!
I put the 144 block of settings, but all blocks except one remained 89 days!ALL BLOCKS 89 DAY BUT I STAY 144 BLOCKS IN SETTINGS!!!!
Can you that the answer to this?

https://blog.greenaddress.it/2of3recovery/
I did everything as instructed, but I wrote I have not enough money!

AND TELL ME PLZ WHERE MY MONEY!!????????

LordofOnorth,

It is not clear what you are doing. Do you have both 2of2 and 2of3 subaccounts to recover?
Can you send to our support email info@greenaddress.it a screenshot of the problem in Gentle?

You shouldn't be using our 2of3recovery guide if you didn't create a 2of3 subaccount in settings.

If you get a "Not enough money" error in general it means you are trying to send more than you have once you take into account miner fees, have you tried sending 0.0001 less or so?

Are you kidding me?
I went to the support of 3 letters with screenshots and on reddit have all my screenshots that I was lecturing .
Gentle does not allow me to withdraw money , and I have made in the settings 2 of 3PF account , but the money for it is impossible to trasfer to him.

http://f-picture.net/lfp/s010.radikal.ru/i313/1510/8f/41d0070af097.jpg/htm CANT REDEPOSIT

http://f-picture.net/lfp/i072.radikal.ru/1510/a3/5c95922e4f62.png/htm SEE IN THE WALLET ONE HAS IS EXPIRED BUT IN GENTLE NOT EXPIRED!


I do not know what to do , I 'll do anything you wrote and nothing helps ! I am ready to pay 10 % of my BALANCE IF YOU help me , I'm VERY beg you !

I cant wait 90 day plz help me!

If you change the nlock time to a different amount of blocks, it will apply only on future transactions. You may need to stay calm and wait until problems are fixed (if there is any problem), or wait 89 days. This is why every time I change that value, I re-deposit the founds.

LordofNorth

We are working on the redepositing issue, as for your recovery:

Go in settings, set nlocktime to 144 then click Save.

Then Click on "Send all nlocktime transactions via email'.

You will receive an email with a zip file. Use THIS zip file so you don't have to wait 90 days but just 1 day.

Wait 24 hours/1 day and only then use Gentle inside Firefox with your new zip and your mnemonic passphrase.

I can try to make some screenshots if needed.

By the way, your last screenshot is not loading.

http://i072.radikal.ru/1510/a3/5c95922e4f62.png
I've done everything you've written , but Gentle only one transaction became 24 hours .
Now I repeated , and sent to nlocktime email, within 24 hours I will not go into the Gentle, and then check your theory .
But I really hope you 'll fix my wallet before, I 'll be very grateful ! VERY YOU ASK

Thank you for your participation, I hope you

Are you working on any another issue than the redepositing?

I am not able to make any outgoing transaction more than 5 days.    (or this issue is the same as the redepositing? )

"Transaction failed:Internal Error"

How many more days do you need to fix this issue?

chmod755, what makes you say that?

We are working hard on all bugs we know of and all support requests.

Not all support issues can be solved in a day or two and we never claimed our software is or even can be 100% free of bugs.

Sometimes bugs are a combination of factors and are harder to reproduce and may only affect one or a few users. Sometimes they affect more people and are easier to reproduce.

The recent 'spam' attacks (but also ddos weeks back) also have required more resources/time dedicated on improving the service.

Nonetheless we are committed to fixing all issues we encounter and improve the platform.

If there's something specific you think we should be doing please let us know we welcome suggestions.

chmod755,

Which language? We should remove or fix the translation if it is not good enough. I'm sorry we have bad translations.

Can you send an email to our support to solve your issue? info@greenaddress.it

Thanks

You are right.

Greenaddress does nothing.   

I asked a simple question but 2 days left and no answer.

You cant reduce the wait from 90 days to 1 day.  If you set nlocktime of 144 blocks it has no effect to your current wallet . It has effect only to the new transactions to the incoming transaction, but who the hell will send any funds into a "locked" account.

This is your system and you try to mislead everybody with this 1 day nlocktime setting that there is no issue  evereybody can get back its funds within 1 day, or you are not aware your own system how does it work.

So now i have to wait another 83 days to get out my funds from greenaddress, but i am not sure that it will work as nothing works at greenaddress.

DO NOT USE GREENADDRESS.   Use it only if you want that your funds to get stuck for months.

bgerg,

Could you try now to either make a normal transaction or to redeposit?
The issue should be solved.

regarding your question: as you know, I mentioned we were working on a fix.
Sometimes it's hard to know when it will be fixed and any ETA i could give at the time would have been wrong.

In these cases rather than giving false ETAs we prefer to be more generic and work hard at solving the issue as soon as possible.

Thanks

LordofNorth,

we think the issue should be fixed for you too, if not please let us know

thanks

It works now again. 

But you could answer to my question that my problem is the same issue as/connected to redepositing, but you said nothing.
So i supposed that you ignored my question because you thought that this is not an issue or you do not know what causes my problem.

And you could say that you give 50% chance that it will be solved within 1 week. 
If you say nothing i can suppose that this is a so huge bug that you wont be able to solve it. (so i have to wait 90 days... )

Why can't you allow users to download your client directly on your website?
I don't use anything made by google or apple. So where I could download your apps?

Hi HardcoreSuperstar,

At the moment you can find all our wallet apps on GitHub only in non binary forms, however:

- the Chrome App doesn't require to be built, it can be run without Google store by using the Chromium open source browser and downloading the latest release from GitHub https://github.com/greenaddress/WalletCrx/archive/master.zip, more info on this video https://youtu.be/zF3Xar5hJ_0

- the Android apps can be found and downloaded with or without open store in binary form built by f-droid here: https://f-droid.org/repository/browse/?fdfilter=greenaddress&fdpage=1&page_id=0

- For iOS we don't have the app in alternative markets but we'll revisit them and see if we can publish the app

We are also considering adding to our sites as well as github signed binary releases to make it easier for everyone to find them.

Hello,i added to my green address wallet 12 bitcoin,and when i doing redeposit then WRITE INTERNAL ERROR
WTF??????????????????????????????????????????????????????
U REALLY????????????????
I send message to info@greenaddress.it

You really lost 12 btc, that sadly to hear. I hope they will recover them. Untill i hear anything new, i'll pass this one.

Unconfirm transaction for three  days is the whole green address system down. Has anybody trasfered bitcoin since then ?

It works now for me, but always asking for redeposit. (I did it 2 times but i always get a pop up message to redeposit.)

I created a new GreenAddress on the web. Enabld Google Authenticator.

Signed out, sign in via a new IP on Tor Browser and it only asked for my mnemonic to let me in, not the 2FA code. Is it the way it supposed to work and maybe it only asks for the 2FA code when someone initiates a spend from my account?

Hi,

new user here, trying to send some coins from my green address wallet, after I have filled in all the required data I click on review and send money button and wait untill it hits 100% and......nothing happens...hours later my money has not been sent.

Need help with this one!  ???

is this still in beta mode would like know how our friend lost 12 btc (hope that wasnt some unconfirmed funds)

and is the security of the green addresses top notch

Ok, problem solved, managed to send money using my phone via green address app, didnt work on the web version ( tried with multiple pc´s )

I am experiencing a big issue with greenaddress.

In short I cannot send funds to anyone... every time I try to send money I see a message stating "Transaction failed: undefined"  :'(
How can I fix it?

Problem solved using Chrome instead of Firefox.

Checked the site and checked also the mobile wallets but what is the difference between greenaddress and greebits?

GreenAddress SegWit test site is not working.
https://segwit.greenaddress.it/en/wallet.html#/

I have created a wallet and when I try to log in the site ask me for a PIN creation. After I insert my PIN its not possible to advance to the wallet.

Did someone already test segwit version of greenaddess successfully ?

+1 in that "internal error" :(
can't send funds to anywhere :((((
1 day has passed ... contacted the email from support... still can't send :((((

anyone else having this issue with greenaddress wallet??
they don't seem to reply to emails :(

I stopped using GreenAddress because the author never responds to email. It looks like it's been abandoned. I hope you get your coins out.

Same to here.

I stopped using GreenAddress some months ago. 

:(((
still no reply from them at greenaddress :(((

ho well .

hey guys...
today i can't login into my greenaddress wallet...
anyone with same problem?

Is GreenAddress still a viable wallet? It seems to be an abandoned project. Is anyone still using it?

I tried to connect on GreenAddress, but it says:

The service is currently unavailable!  :o

It's possible you caught one of the servers while it was being deployed but I just checked and everything looks normal. Likey the issue only latest a few seconds while the new instance was added.

Is everything fine for you as well?

Thanks

Yes, now it works  :)

Got a lot of money stuck in greenaddress at the moment on multiple accounts.

Biggest problem is that when i try to send money out, after confirming my actions with Trezor, it asks for an email code confirmation and sometimes it even doesn't do that. Point being, i either cannot see the email code confirmation popup at all or when i try to enter the code the popup disappears.

What's going on?

Also there are no replies to e-mails. Having issues with 2FA and recovering an account but the support is just not replying at all. I mean - zero responses in three weeks!

Support the project or close it and send funds back to the users.

/u/BitFast is more active on reddit

https://www.reddit.com/r/Bitcoin/comments/4iribc/greenaddress_lost_google_auth/#d30ifqh

Greenaddress still not fixed the issue i have mentioned more than a year ago.


Login with your 1st wallet
Logout
Login with your 2nd wallet
Logout
Login with pin number

It will logged you into your 1st wallet and not your last 2nd wallet
(1st wallet pin == 2nd wallet pin,  it would be interesting to test if pins are not equals then you could login into the other wallet, it would be a huge security bug)

So you can not use your 2nd wallet pin, you have to use your mnemonics always if you want to login into your 1st wallet (until you clear your cookies)

When will be this fixed?

I am not sure whether you have got an iOS application for this or not but it should be available to ensure you do not miss any customer of yours as bitcoin has approached main stream media and is getting bigger day by day .
