Great work mate :)

If an address hasn't received anything transaction, the transaction page looks "horrible". There are messages like "null / 0" and more stuff like that. Keeping it blank might better.

Example: https://www.blocktrail.com/address/1Ji1E5CgHW2XqUj8SjznBCyQWcPXejxMz6/transactions (https://www.blocktrail.com/address/1Ji1E5CgHW2XqUj8SjznBCyQWcPXejxMz6/transactions)

Id like to use your API for a tiny ruby script that asks for the latest hash[1], but I was unable to find any information about it.

[1] basically like this: http://blockchain.info/de/q/latesthash but not bc.i, since they tend to mess the data up.

Shorena,

We're happy to announce that we launched our API this week, providing you exactly the kind of in-depth bitcoin data you are looking for.

For example, for your query, we provide you with the latest hash, along with additional information about the latest block:



Our API is really easy to use and comes complete with SDK's for PHP, Python, and NodeJS. We'll be introducing more SDK's soon (ruby included!)

To get your free API Key visit https://www.blocktrail.com

Full documentation is available at:  https://www.blocktrail.com/api/docs

Nice site!  We need more developing tools for bitcoin.  When you go on youtube I'm surprised there aren't any howto videos on web dev with bitcoin. Not even something simple to get people started like how to make a faucet or build a charting website... Anyways, really cool tool. I'll bookmark this one.

Wow, this site is very good
I just try input my own address, they automatic give many detail about my address

They even i got bitcoin from gambling & mining  ;D
It show my bitcoin value in USD too  ;D
And how many & where my address mentioned

I'm gonna bookmark this site  :D

Thanks for the nice comments, if you have any feature requests, please let us know!

Good point and thanks for the comments. If there is anyone in the community that is interested in making these kinds of tutorial videos using our API, we'd be more than happy to support this kind of activity.

 

Personally I like that it tells me social media mentions and a break down of what funds may be. For example mining or gambling.

What all sites are mentioned in 'Mentions'? I only found Bitcointalk in it. It would be good, if it also searches in popular forums like reddit-Bitcoin/Litecoin, Stackoverflow-Bitcoin and litcointalk.org . :)

Congrats, now goocha.in supports BLOCKTRAIL. ;D

   ~~MZ~~

it includes /r/bitcoin and stackoverflow is a good one too ;-)

Wow I just signed up to your website http://blocktrail.com, you guys are putting together something pretty cool and useful!
Sounds like you are going to be even better than Blockchain.info!

I'm going to use the free tier for the moment.
Any API development updates?
Are you guys going to have your own BTC wallet too?
If yes is it going to be available to use for other Alt Coins too?

Also I noticed there is a "Mentions" function on your site:

https://i.imgur.com/Y2iYiwD.png

How does that work? If someone mentions a specific bitcoin address on a forum it shows up via your API?
Very interesting have to say, if you could point me in the right direction on where I could learn more about that.

Potentially this function should work on any forum like BTCTalk and maybe Reddit?

Yes that is correct.

I mean really its just a bot looking over specific sites for text.

Extremely nice looking site and extremely nice tools. I think I'll use this for a couple projects just to try it out. Very impressed!

I am writing a block chain explorer for iOS using blocktrail.  It has been very easy so far.  Seems a more fully featured api than the other one.

A slight typo in the address section of your docs though,

unconfirmed_sent           (integer)   The total number of unconfirmed transactions for the address (both received and sent).
unconfirmed_transactions   (integer)   The total number of unconfirmed transactions for the address (both received and sent).

I have got a list of transactions for an address back using your api.  Now, i want to colour code them with green=incoming and red = outgoing?  How do i know which is which?  Everything seems to be positive.

I really like your block explorer, I prefer to view the blockchain fast and lately blockchain.info has gotten a little slow for me and which is why I have shifted to this.

Quoting two unreplied questions. :)

Yes it can be used for a faucet, we actually used it for our own faucet.


We are still investigating this, maybe in the future.

If you want fast response on your questions, please send us an e-mail or use our support system.
Thanks for the feedback!

Jop

1. Do you have any plan to open the source code like insight.is ?

2. Any plan to provide something equivalent to blockchain.info's send & receive API ?

Can you confirm to me that our CTO helped you out fixing this issue ?

1. We contributed to various bitcoin related projects in the process of making our API and SDK and our SDKs are open source, but we're not planning to open source our server architecture
2. We now offer Multisignature + HD capabilities through our "wallet API". Im not sure if this answers your question though.

Hi dude,
It's pretty good and well designed , are you planning to make an API for C# or ASP.NET  anytime soon ? that would be great and increase users of .NET in my opinion

Hey Rappelz,

We do have a community edition BlockTrail SDK for .NET  https://github.com/raymens/BlocktrailSdk (https://github.com/raymens/BlocktrailSdk)

awesome website , all you need now is making advertising so more people come and use your service .
more then epic ! I like that "mentions" thing and i don't even know how you coded it , i assume you made that option for few known website and not the whole internet because i don't think it would be possible to get Usernames like it does on Reddit , Bitcointalk on each random website .

Thanks for the support!

That's right reddit and bitcointalk only.

Interesting news! ty for sharing, I'll put a nice spin on it :)

Cool! By the way: blocktrail now displays BIP100 and 8MB votes all across the site https://www.blocktrail.com/BTC/blocks/1

Why does block 370704 have the 8MB tag and block 370705 does not have not the tag, when the coinbase transactions of the both blocks have the same "BW Support 8M fisher jinxin /BW Pool/" message?

Hey Buziss,

small mistake when we were rolling out the changes, still had to run a small script to update a few blocks, fixed now!

thanks for giving us a heads up!

Recent Bitcoin Blocks: https://www.blocktrail.com/BTC/blocks/1

Glad to hear those two major pools are on board with BIP100 as well.

Interesting development, definitely.

Cool feature you got there. Also, it's nice to see BIP 100 getting support from large players in the industry!

A Closer Look at BIP100: The Block Size Proposal Bitcoin Miners are Rallying Behind

https://bitcoinmagazine.com/21747/closer-look-bip100-block-size-proposal-bitcoin-miners-rallying-behind/

Is it possible to use your API without installing the SDK via composer and SSH?  Is there a simple way to download it as a PHP library or multiple libraries and just use an include?

Hey, we highly recommend using composer when doing PHP development and if you lack SSH access to a server (we also highly recommend not using shared hosting :P) I'd recommend you run composer install on your local machine and then upload the vendor directory to your server.
Composer is the one of best things that happened to PHP in the recent years (eventhough it could be better), you should use it ;-)

With all the different classes in the SDK and it's dependencies (there are quite a few required for the crypto stuff) you really need to use the composer autoloader, however it can work side by side with any existing autoloaders you already have from your frameworks etc.
If you have a strong objection against running composer install locally and then uploading those files to your server, we could try and package the SDK, the composer autoloader and it's deps as a ZIP and then you could download that include the composer autoloader.
But the only difference from the first aproach is that we create a ZIP that you unpack and upload instead of you just running composer install and upload the result.

Ahh okay, I'll give that a try thanks!  Yea I'm on shared hosting since it's the best solution available while on a budget ;)

So just to clarify, BIP 100 is 8 MB blocks but BIP 101 is something different, it's XT's crap?

No, when you see BIP 100 it means the miner is voting for this BIP.

When you see BIP 101 it means the miner is voting for that BIP, BIP 101 is also BitcoinXT.

When a miner mines with a 8MB vote then what they mean is that they support a bigger block size but don’t seem to have an explicit preference for any BIP’s.

More information can be found here: https://blog.blocktrail.com/2015/08/miners-block-size-vote-explained/

Title on this topic was "Web wallet" since long time ? :o I'am not sure ..
Anyway what I wanted to about is this : https://wallet.blocktrail.com/ (not sure if it was supposed to be a secret) but tomorow is 1 September should we expect the launching of this wallet tomorow , that would be epic honestly and if you could tell us the advantage of this from Blockchain.info web wallet if there is any .

What does everyone think about our new logo? :D :D #Google

https://i.imgur.com/wWrs4QE.png?1

Hmmm, I prefer the red design.

I prefer the first design aswell , it fits google very well but not BlockTrail in my opinion .
Anyway I don't mean to be annoying or anything but could you please answer me here : https://bitcointalk.org/index.php?topic=756279.msg12291396#msg12291396

Haha, good one! Except you fou forgot to tilt the "L".
The google logo "change" was under-whelming.

Oh yeah!!! Damn it. haha ;)

Oh nice! Will try to get a hold of him :)

I was just checking your website and I see that you finished your wallet . It's looks very simple and I have few awesome suggestions that should make it better if you don't mind of course :)

• Ability to import different wallets files [Electrum , Bitcoin Core , Multibit] into it
• Ability to see all our adresses and have full control of them including Signing and verifying messages
• SMS  2 Factor authentification
• Print Paper wallet from our adresses

NEW ARTICLE ON TECH CRUNCH: BlockTrail Launches Multi-Platform Bitcoin Wallet With No Access To Your Coins


https://i.imgur.com/Dfa8yFm.jpg (http://techcrunch.com/2015/09/12/blocktrail-does-a-bitcoin-wallet/)



http://techcrunch.com/2015/09/12/blocktrail-does-a-bitcoin-wallet/

This is great news for Blocktrail! Will try to cover it on a few sites in the next week or so :)

It looks nice to try.

I really enjoy the wallet :D

great job!  ;D

New design is awful. Especially Explorer!

Loving the new wallet, will deff use!!

I also enjoy the new face-lift of the website.

 :)

hi, i just installed blocktrail wallet on my android phone. And i found out about Promo Codes.
what the usage of that promo codes?? and if i want to use it, how to create the promo codes?

We will take a look at these suggestions further. Thank you for your feedback, keep it coming!

Also please have a look at the QR scanner. I'm getting a forced close on CM11 (4.4.4) @Galaxy S2.

I set up a support ticket. Thank and i'll keep you posted.

I can keep the suggestions coming till the end of the world if you want however Iwant to know if you guys really will take a look on them or not . Also if you could make an email call it suggestions@blocktrail.com or something that would be awesome so we can send suggestions , for the meantime should I keep sending the suggestions here ?

Also I have a question , it says that we have full control on our bitcoins however there isn't the ability to export the private key , so how come we control them :o

Hey,

Promo codes are there for when we run promotions. At the moment, users cannot create their own promo codes.

We have updated the front page with our new product and designs. Let us know what you all think.

The Blocktrail wallet is a HD wallet, this means that all your private keys are generated from 1 master key, which is generated in your browser/app and then encrypted with your password before sending it to be stored on the Blocktrail servers.
Additionally the Blocktrail wallet is a multi-signature 2of3 wallet, 1 is your primary master key, 1 is your backup key and the 3rd is the blocktrail server key. 

So because it's a HD wallet you don't need make paper backups of every private key for every address, the first backup is enough for almost infinite amount of addresses.
It's also not recommended to 'export' any of the generated private keys, but more important, because of the multisig nature of the wallet there's no other wallet that by default can import it and can spend the bitcoins.


Your feedback is ofcourse very welcome, I think I explained about the keys, as for the importing of other wallets, the only way of doing this is by sweeping those wallets and moving the bitcoin into a new address, I think you're right that it's a nice feature to have to be able to do this in our wallet for users who want to switch, I will put it on the list but I have to admit that atm there's a lot of other things that are higher on priority then this one.

We have two-factor authentication using Google Authenticator (or Authy) already, is there any reason you prefer SMS over those?
The main reason for us prefering Google Authenticator over raw SMS is that the costs of an SMS every time someone logs in or does a transaction get's expensive pretty quickly!
We are planning to add a fallback to SMS though incase someone looses his Google Authenticator.



PS1. There's support@blocktrail.com and anything going there will be processed and answered asap!
PS2. When we say "full control over your bitcoins" the thing we actually mean / value is; "Blocktrail does not have access to / control over your bitcoins".

Thank you for your response Mister the CTO ;D

Now I understand I suppose , but in case BlockTrail goes down for one reason or another how are we supposed to get our bitcoins back if one of the private keys is stored on your servers as you are saying since it's Multi signature wallet ? Because I'am not sure what each of the Encrypted Primary Seed , Backup Seed , Encrypted Recovery Seed are used for because I don't see any settings to be able to import them .
However at the end of the PDF file I see that we should use your SDK and I think this is one bad thing , isn't ? I mean for people who don't have knowledge in programming it would be little bit hard to do honestly .
Also not to make Blockchain.info looks like bad or anything but could you please tell me what should make me switch from their wallet to your wallet .

Also at the end , you said there is somethings that have more priority on the meantime , could we know what are those things and could we expect updates soon ? ;D

Great site. Blocktrail.com became my favorite site to check Bitcoin addresses and transactions. I like the layout. It is very user-friendly. Some more charts would be great.

Thanks a lot for that :)

At the moment we are working around the clock to iron out bugs and get the wallet working at top notch. We intend to add more charts someday, hopefully soon. :)

I've already answered your question on the other thread about the private keys: https://bitcointalk.org/index.php?topic=1180096.msg12426557#msg12426557

Also to answer your question about switching from blockchain.info, i'll try to be as objective as possible.

The features:

on the mobile app we believe we have created a very user friendly interface that we hope should allow anybody to start using bitcoin. We have some nice features that blockchain.info lack, such as the ability to send to contacts in your phone without having to ever request an address from that user (one is generate automatically for their wallet). We also use the names and profile pictures of your contacts so you can easily see who a transaction was sent to or received from.
Another nice feature is on the transaction display. You can see what the value of the transaction was at the time it was sent, and compare it to the value now to see how much it has grown/decreased in value in your local currency.
The wallet also supports bitcoin URIs, so if you click on a bitcoin hyperlink it will launch the app automatically and fill in the address and amount on the send screen. We also have dynamic fees integrated, so when someone decides to do a stress test on the network your transaction will still have a higher chance of getting into the next block.
What else....we're multi-platform ( iOS, android and web browser...like bc.info), have a qr scanner in the app, generate new addresses automatically whenever you go to the receive screen (which you can copy, email or sms to someone). Oh and you can specify the amount to receive and the generated QR code will include this.

And now the technical aspects

Firstly bc.info is not an HD (hierarchical deterministic) wallet. So for every address you generate, you need to backup the private key separately. If you ever lose one of those backups you have no way to recover the funds held in that address. You also end up with an insane amount of backups (as you should not be reusing addresses, and generating a new one every time you receive funds). With our HD wallet you can create a near infinite amount of addresses and only ever need a single backup of a master private key.
Another advantage to using HD wallets is that we are able to generate new receiving addresses for a wallet without even needing their private keys. This allows you to never have to reuse addresses (which is bad for both parties' privacy) and still be able to send to someone without needing them to manually generate an address and send it to you.

Then there is the fact that we're using multi-signature technology, 2-of-3 to be specific. There are a lot of security advantages to multisig and features that we'll be able to add (such as spending limits, kill switches, address whitelists, etc) that will help you have greater control over your bitcoins and security against theft and hackers. It also means that you can use blocktrail as a service without ever having to give us access to or control over your bitcoins, and if anything were to ever happen to blocktrail you'd still be able to access your bitcoins and send them to another wallet. This includes if we get hacked. The hackers wont have enough information to do anything to your wallet, unlike with bc.info in which case they have an encrypted private key which they could brute-force attempt, rainbow table or use some other method to crack and then empty the funds in your address.

You definitly convinced me for what comes to the Features part , now I have a question and that's why I recommended SMS Two factor authentification because I don't get how this one works .
It says either download GOogle Authentificator or Authy and scan using your Smartphone but I don't have one honestly , I have a tablet but too lazy to use it .
however it asks me also to type that code manually as another option , but when it type it on the next TextBox it says it's Invalid token what I'am supposed to do ?

I just sign up to blocktrail wallet as a recommendation from a friend, I do not own any bitcoin yet so hopefully soon :)

Because the address starts with a 3, does that mean its a multi signature? I cannot import my private key to another wallet?

Thank You, It looks great.

this is the one of the best block explorer but i will still prefer blockchain as the number 1 blockexplorer till now because it is not viewable at some devices

I believe I just found a bug or something , let's get started :

First day I made my account on BlockTrail it asked me to download a PDF file and keep it safe , which I did and printed and now it's asking me once again and I'am not why .

All informations between first and second PDF are totally different (Seed and all) but what I noticed that it totally different is this (first PDF wouldn't make sense if it only says blocktrail-wallet to be honest , second should be the correct one I guess) :


First PDF :   on the "Wallet Identifier" Part on the first page it says blocktrail-wallet and that's it .
Second PDF :   on the "Wallet Identifier" Part on the first page aswell it says blocktrail-wallet-randomStuff

randomStuff represent some random letters and numbers , I just didn't want to post incase that can be used to get my wallet .

I've sent this to our developers. Stand by for more info, i'll PM you when I get a response.

Ouch, painful bug! Sorry about that, we rolled out an update that adds the 'randomStuff' at the end, but the wallet didn't properly recognise the fact that a wallet already existed ...

I've fixed the issue;
 - if you had a balance on the first wallet then if you logout -> login it will log you back into the first wallet.
 - if you did not have a balance on the first wallet then if you logout -> login it will log out back into the second wallet.

in both cases the other wallet is not lost, you just can't get to it anymore until we add the feature to manage multiple wallets to the GUI (in a future update).

Thanks for fixing this even if I didn't much understand how and what I'am supposed to do now . I had no balance but I don't see any tab to choose between wallets , should I simply login and I'am fine ?
and which PDF backup should I keep , both of them ? also if you could answer my question above about the Two factor authentification please because I want to enable it before I start depositing into my wallet .

Both wallets are safe we are currently working on adding the "manage other wallets tab" You can simply login and you are fine, if you add bitcoin you will always login to the wallet with bitcoin.

Keep both PDF's to be safe.

Two factor authentication(2FA) works on the mobile app, it only asks you for that when you first login. We are aware that 99% of users have the 2FA app on their phones so that's why we only ask for it when you first login. Later on we might make it optional, we're considering various scenarios.

Thank you

I think this wallet is very quick, It looks very nice and works very well.

Could I install the library on a shared hosting? My hosting provider told me that I could install only on a server with root access...

Hey bterproblems, i've sent this comment to our dev team, we'll get back to you soon. :)

Thanks

Thanks! Enjoy :) we are constanly trying to make it better.

We have updated many iOS 9 app bugs, download available at app store. :)

Can we expect any soon updates for what comes to the Web wallet ?

Do you mean additions to the web wallet or bug updates? Have you found a bug on the web wallet? let us know

I meant additions to be honest (don't forget the suggestions thread ;D ) and I'am not sure , the only bug I found I reported already and you guys fixed it in couple of minuts .
and you also spoke about adding the ability to switch between different wallet since that last bug :o

Oh yes, we ae aware of suggestions and plan on adding some of those ;) right now though we are working on ironing a few more bugs that have popped up. Thanks Omega

So, what happened?

Hey,

you could try running `composer install` locally and then uploading the `vendor` directory, but most likely you're also going to need a few PHP extensions installed which might not be installed on the shared hosting (which I guess is why your hosting provider told you it's not possible).

tbh we also strongly recommend doing bitcoin related things (or anything really) on a server with root access, either self hosted, rented or a VPS.

Pm me if you have any more questions :)

Very excited to use the Blocktrail wallet. Just downloaded on Android and set it up. For some reason I never got the SMS when trying to verify my phone. Did other people here receive the SMS? I will try again later, perhaps it's just something to do with telecom network. Wallet looks great - will fund it soon. Keep it up!

SMS verification is working well on mine. Right after i enter my phone number i got the verification code by sms.
maybe your phone operator have some issues.

Maybe you can help me out. I just tried to log into the web wallet with my "dev account". The old ones that you needed to get an API key. I got the error:


which I did.

On the dashboard there is the option Wallets -> New Bitcoin Wallet. It requests an Wallet Identifier and a Wallet Password (twice). All fine, until I hit "Create Wallet"

Tor 5.0.3 on Win 8.1 Pro 64Bit:

Any idea what thats about?

One more thing came up regarding your "Verify Signed Bitcoin Message" here -> https://www.blocktrail.com/BTC?verifysignedmessage=1

Someone staked the following message here -> https://bitcointalk.org/index.php?topic=996318.msg12567926#msg12567926


Note the trailing space at the end of the message, the @ is also uncommon. Regardless it does not verify.

https://i.imgur.com/Wr4kNhd.png


Even though bitcoin core does without issues:

https://i.imgur.com/cXV4sGq.png

"developer accounts are limited to 432,000 API requests per 24 hours, at a rate of 300 request per minute.

When you reach the rate limit you will get an error response with the 429 status code.
We will send you a notification when you're getting close to the rate limit, so you can upgrade in time or contact us to request an extension."

IS it true that you offer such amount of API requests for free? And there will be no issue like with blockchain who blocks API IP address after small portion of API requests exceeded?

Also when create wallet get an error: Expected Buffer, got String "f986ea8598b3a41d72905f9c2190a59577f576a10bd424a8b846375f8e750bae6a6c27d56cf780c ec2c865f529df48c6e85d0136faface1dad70f262d1e3b60c"

Hey Shorena and mihtju,

I have forwarded these issues to the dev team, please stand by... we are working on it.

Correct mihtju we do provide this for free, and no there will be no blocking issue when you exceed. Just please contact us if you do intend to exceed.

Thank you and we be back shortly with a fix to the "expected buffer, got string" issue.

Thank you for your fast reply and help. Hope that this issue with Buffer string will be corrected shortly.

Fixed, the frontend code was trimming off the trailing space at the end!

The issue with the "Expected Buffer" has been resolved, sorry about this, side effect of some updates for the consumer webwallet ...


As for the rate limits, those numbers are true (otherwise we wouldn't say they were) and atm our system can only manually ban IPs, and that's only really for abuse (ie someone who's obviously rotating multiple API keys to get past the limit), so hitting the (free) rate limits is not a problem at all except that you'll have to wait before you can get the data you want.

Also, if the limits are really a problem then feel free to contact us to discuss an upgrade (could even be free depending on the situation).
Though they really shouldn't be with 100k transactions/day on the whole bitcoin network 400k requests should be enough for you to completely sync the whole blockchain xD.

Thanks for the quick fixes, can confirm the signature now verifies without issues and updated my guide accordingly.

Looking forward to testing the wallet later when I have more time.

Regarding the SMS, yes, it was my carrier's problem. I have now received the SMS codes and verified my phone number. I noticed the Receive address in the phone's wallet is a multisig address. Interesting...

Good to know. Yes that's a multisig address. ;)

Thanks, let us know what you think about the wallet.

Strange, I got again the same buffer string error. Sure that everything is fine?

Sorry it was my issue : everything works fine. Thank you BlockTrail.

I was reading whole thread and seems that Blocktrail seems nice, but I have a question regarding you wallet. How to you treat double-spends?

Yes I also think that blocktrail will gain huge popularity very soon. Its something outstanding what are they offering to us.

Same feeling here as well. I read that you, same as I are interested in API, have you tried it out in real-life-conditions? Does it work well and can it handle that much requests as they promise?

Now that my Android wallet is set up and funded (looks great!) I've decided to play around with the Node.JS SDK. So far, so good. Great service guys!

I have sent this to the dev team.

No big deal, but I was seeing the same transaction show up two times when I accessed my wallet via the web. It's OK now, and only shows one - perhaps it had to do with the malleability attacks?

Yes, it had to do with the malleability attack.

I created a new account at blocktrail today.
I sent 0.1 BTC into my new blocktrail wallet.   
It showed up correctly, but next time when i checked my wallet , it showed 0.2 BTC ????  After some click on the page it showed again 0.1 BTC correctly.

Now my only one transaction is still pending (on blocktrail wallett transaction page), but when i check it on explorer the transaction has 7 confirmations.
https://www.blocktrail.com/BTC/tx/a25677cf1c272d6fa484b75d1fe0dcfb4df368e13a8dd870f273d1518213cec8


When you start using a new service and face 2 issues within 1 hour is not very promising....

Thats the malleability attack people talk about. It creates a twin transaction with a different hash (TX ID) that is otherwise identical. Most wallets are currently ill equiped to handle this.

Just downloaded the wallet, and I must say that I like the interface. It's not that hard to be familiar with seeing that the UI is very friendly to new users (and I like the theme too, lol). What I like the most is the API and the bitcoin block explorer. I even have it bookmarked just in case I want to do a quick search on a transaction. :)

Awesome, thanks for your support dothebeats <3

Wallet: Android

When scanning a QR code I'm getting an error message:


Anyone else? Tried multiple QR codes that I know work.

Any feedback from the dev team regarding this?

Your web interface a little bit buggy ...

Still pending in the transaction list and after i click onto the transaction to get its details while block explorer says it has 207 confirmations.

https://i.imgur.com/irn0sps.png

I think this was the last day i used your wallet

After logout and login (On october 8 i had only one  0.1 BTC transaction, the transaction list is a full mess)
https://i.imgur.com/xPl68z9.png

8 btc gone?? That was a big amount.
I'm sorry for your lost.
Have you trace your transaction??

Not lost.

But the transaction history is full mess and i do not trust in a wallet that is not able to solve/implement a so simple function like transaction list.

Do you mean that that you had 0.1 BTC in your wallet and once logout and login you found 8 BTC ? Make sure that those transactions are legit (I mean check the transaction ID on blockexplorer to see what's wrong)

No.

What i say is this in words:

I opened blocktrail (after 1.5 days) and transaction list showed that my 5.478 BTC was still pending despite of it had 207 confirmations.  (my 1st post.)
I made logout and login and my transaction history was a full mess.  (my 2nd post)  . I have not lost any BTC.

Transaction list should have look liked yesterday:  

Oct 16 : 3 BTC  (pending)
Oct 15 : 5.478 BTC
Oct 8 : 0.1 BTC

To be clear, the QR codes I'm scanning are of the type: bitcoin:1blahblahblahblah?label=blah ... This might be part of the reason?

I am missing "labels/tags" in transactions...you should allow people to tag new address when its created to receive BTC. Even in transaction popup there should be address shown so I dont need to check it manually (but labels/tags will fix this too). Thanks!

Good job with your block explorer.
I would like to use your wallet, but I didn't actually get how to import a wallet with the private key, could you please help me with this.

As far as I know they are not allowing such service so you won't be able to do that , at least not for the web wallet that I used ... You still can import them to blockchain.info and then send them to your BlockTrail Wallet .

Hey all,

Thanks for your feedback, we are constantly monitoring all feedback, suggestions and issues. We attempt to fix and add things to our wallet and service as fast as we can.

Thank you for your continued support to Blocktrail.

If you haven't already, follow us on Twitter and Facebook: www.twitter.com/blocktrail www.facebook.com/blocktrail

What about my query ?

Have you tried following the README?


https://github.com/blocktrail/blocktrail-sdk-php#requirements

I dont like the wallet but the explorer. It is useful to lookup for duplicate bct account. So we can stay safe from online scam.

BlockCypher, another API provider is providing a compiled folder for direct download as an alternative to composer install.

https://github.com/blockcypher/php-client/wiki/Installation

I think, providing such an option would be helpful for developers who are doing small projects to be deployed on shared hosting.

Hello!

I am having trouble implementing the WebHooks from API into the system. I am using PHP.
Step 1 is ok, where I generate the wallet and store it in the DB.
Next step I cant get working, where a webhook needs to send data to the callback, and accordingly react.

I am willing to pay for helping me get this code part done.

Here is the original post: https://bitcointalk.org/index.php?topic=1333254.0

Thank you, Devsoft™.

I might have found another bug with your signed message verification.

The following sign message was recently posted


and electrum's GUI just did nothing when I tried to verify it, so I tried to verify it via blocktrail and it passed with OK, signature is valid!.

Its not though, its missing a "=" at the end,

looking into it, thanks

hey, thanks for getting in touch! this could have been a pretty serious bug, but luckily it's not ;-)

the signature is 'base64' encoded which officially should have a trailing '=' if the last 'group' of bytes is only 2 bytes and act as a 'padding' to explicitly declare that you intended the last 'group' to miss 1 byte (base64 is chunked in 3 bytes per 'group') and a trailing '==' when the last 'group' is only 1 byte.
the javascript implementation of base64 actually silently asumes that if you don't have a trailing '=' but the last 'group' is only 2 bytes that it's supposed to be 2 bytes and doesn't error over it.

so when decoded (in javascript) from base64 into binary (or hex) "HyEuQEIIi5KS0dqyCaIWh6a5A3wIMFqkSEehuNa7jOUZTSyLa08czuASi5RUcj78hPI5PMNec0w6Xhz flMbFNcM" and "HyEuQEIIi5KS0dqyCaIWh6a5A3wIMFqkSEehuNa7jOUZTSyLa08czuASi5RUcj78hPI5PMNec0w6Xhz flMbFNcM=" both result in the same data.

Thanks for the explanation. Sounds logical in the light of the encoding. Would it be possible to show a message to the user? Something like "Your signature is valid, but misses a trailing '='." or "...'=='." respectivly.

My transaction has got any confirmations more than 3 hours.

Blocktrail tx fee problem?

DO NOT USE BLOCKTRAIL

BLOCKTRAIL  ADDED ONLY  0.00003810 BTC  FEE  (on 600$ )

So my transaction never will be confirmed or i have to wait days, weeks.


https://www.blocktrail.com/BTC/tx/b28c4c62119754f55dd9d9f1805e507f9019751a684ba481712208c1012919d9

I'm sorry you're disappointed with us...

Ever since the increasingly full blocks we've started working on better fee estimations (both to avoid too high and too low fees), but this isn't an exact science and there's a few configuration variables we need to tweak on our algorithm to get to the perfect spot.

The key is to estimate the 'perfect' fee/kb based on the previous blocks found, the value of your transaction has nothing to do with that.

I agree, we were off on this one, the fee/kb should have been ~0.00032493 BTC/kb which should have put the fee for this transaction around 0.000121199 BTC.
Instead we estimated 0.00012 BTC/kb and the resulting fee was 0.00003810 BTC.

I've tweaked a few of the configuration variables to make sure that in the future in this scenario it will use a higher fee, while still using lower fees for when blocks are less full.

Ruben
CTO, Blocktrail

Hello BlockTrail,
We're experiencing a big issue with your API and our users are getting mad at me.
Transactions are being sent via the following function:


Unfortunately it works sometimes only, I mean the user has to try withdrawing many times until it works.
Right now I'm using a try-catch method for displaying the withdrawal error cause your API isn't even throwing the exception.
Can you please help us to fix that terrible problem? I want the users to withdraw at first try. Maybe our function parameters are wrong?

Waiting for your response, thanks in advance.

Hello BlockTrail!

I am experiencing the same issue with the "pay()" function. The documentation DOES NOT include ANY INFORMATION about parameters this function is using, which makes it almost impossible to know what params can be passed there.

This issue causes payments to fail almost every time "pay()" function is executed.
The statistic could be it works on 1/10 +/- tries. I have tried everything I can imagine of, nothing helps, without knowing more information, which should be included in your documentation.

This issue is so huge, that it increases server load more than 10 times!

Could you please be so kind, and help out with this?
Thank you, DevSoft™.

OP is not active as he used to be , It would be probably better if you post this on Github or contact them directly  : https://www.blocktrail.com/about

They are not answering to any contacts, emails. Total Ignore from BlockTrail's side.
Like a half year ago the support was ok, now the service seems to be broken.

As far as I know this is the new CTO of Blocktrail > https://bitcointalk.org/index.php?action=profile;u=295029

@CTO I have one request regarding Blocktrail's Slack Tipbot. I have added the tipbot on our channel https://antibitcoin.slack.com

Since the channel is related to AntiBitcoin (a new and popular cryptocurrency > https://bitcointalk.org/index.php?topic=1283271.0) I have an earnest request to add it to the supported currency list so that we can tip members of our channel with our own currency.

Thanks in advance :)

please give PM me privately some info about your account so I can look into it, because I don't see anything 'DevSoft' related in our support mailbox

also if you're using PHP, make sure your SDK version is >= 1.2.20

nothing 'new' about me being CTO but yes xD

the tipbot is completely based on our API/SDK so there's no way to easily adapt it to support another coin. 
it's open source though so what you could do is take the logic of analysing the messages etc and keep that and replace all the wallet code with a small database that keeps track of users addresses and uses the RPC of your own coin to make the transfers.

https://github.com/blocktrail/slack-tipbot

Hello DevSoft,

What issue are your facing? Look forward to helping you.

This is great. It really goes a long way to have a video tutorial - it's often the differentiator between choosing one technology over another. Keep it up!

Thanks, although the credit should be given to "m1xolyd1an" the one who uploaded it!

Nonetheless, good advice. We might begin taking out some more video tutorials in the upcoming months.  :D

Hey Guys - Looking for a little bit of help with your API, we can't seem to get the WebHooks to actually function using the API. Very much could be user error on our part, but haven't been able to get a ticket looked at or our PMs answered.

Any and all help is appreciated (and tipped :) )

Beautiful looking wallet. It reminds me of coinbase.
Your block explorer is the best I've seen, blockchain.info is quite laggy and the interface and color palette is a touch too bland for my taste.

PM responded to! And we don't accept tips for support queries ;)

Thanks! means a lot. :)

 Is this video tutorial good to go with you service?

Yes, it is a not recommended service, I also had faced the same problems at there, for the confirmation of my transactions, I will have to wait for a few more days, which is not favored by me. So, I left already.

Nice, thanks for sharing my video  8) 8)
Wasn't sure if I should do some tutorials on using their actual API library, but I've done so many videos on using APIs I figured it would be redundant to viewers. The UI feature in building webhooks is unique (and awesome) so I wanted to highlight it.   

does blocktrail has option to send payment using curl ?

i mean to send bitcoin payment using url as like :
https://blocktrail.com/send-from/send-to/amount

i don't know how to install plugin on my server..

please anyone can help?

If you feel like making more videos, please do! Contact us for anything as well.

Hi there guys .
Is there is any features you added or bugs got fixed since you first released your online wallet ? or the development has been dropped ?

Hey Omega,

We are moving forward with development and working hard on getting things much better with our wallet.

Blocktrail users,

We are writing up a new blog post with regards to our fee's. We've received a lot of questions on this so we hope to clear up all the confusion.

Thanks

Awesome ! Should we expect a major update anytime soon?

As for the fees , please once you finish the blog post link us :)

Definitely awesome, nothing major that will disrupt API's or wallet users... just making everything BETTER.

Yes will of course pull up the link here for you guys.

BTC

I tried the web wallet once before but I did not like it. I could not edit the fees not export my private keys . and the most annoying this was the address was keeping changing. is there any plans to add more option there ?

no, being able to send coins in such a way requires the server (blocktrail in this case) to have access to your privatekeys, with Blocktrail only you can sign transactions, so that's why the usage of the SDK is neccesary.

our PHP SDK can be installed using composer, which is the industry standard in PHP land

We give you a backup PDF of your seed so there is no need to export your private keys. Our fee system selects the best and most optimal fee. Additionally, in the web wallet options you can choose to have a lower fee - but then you face the possibility of having to wait a long time for your transaction to go through.

HD wallet feature is considered industry best practice - for your safety the addresses keep changing. Keep in mind that you can re-use every single address you have ever used.

Please let me know if you have any other questions.

Thanks

 ;D ;D ;D 8) 8) 8) 8) :D :D :D

You can lower the fee's by clicking on Advanced settings -> low priority bitcoin fee. See image below

https://i.imgur.com/5RalTiH.png

Updates you guys was talking about were made or not ?
Could you also please link us to the blog post you mentioned few days ago.

Updates are being worked on, blog post being worked on. Stay tuned for some news coming out next week.

Thanks.

Hi. I would like to use your api in my website. I will need to have notifications about new transactions that I receive and also I need to be able to send bitcoins automatically to other bitcoin addresses. My website is like a faucet website. Can your api help me to do this job? and also does your api have request limit like blockchain?

We do all that and more, our API request limit is the highest of all API's in the bitcoin space (including bc.info's) and it's totally free!

I'll link you to a blog post tutorial we wrote to help you get started: https://blog.blocktrail.com/2015/02/your-free-decentralized-t-shirt/ (https://blog.blocktrail.com/2015/02/your-free-decentralized-t-shirt/)

Contact support@blocktrail.com if you have any issues, or you can also just contact me here ;)

I remember seeing C# unofficiel API or something , do you mind linking me to it If you guys have one ? I need something updated if possible . (most updated , I may work on updating it more )

Here it is: https://github.com/raymens/BlocktrailSdk

Nice, remember that any updates, tutorials - etc. is greatly appreciated and will be actively included in our marketing.

Thanks a lot. This is exactly what I wanted. I will use it... but I've started coding with php and mysql recently and I want to know more about your API and how to implement it on a website. Do you have any suggestion or any source of information on these subjects?

hi please tell me what is the link you can create an address on blocktrail, if it is created Blockchain so https://blockchain.info/api/receive?method=create&address=...

Blocktrail is one of the commonly used APIs out there and I guess they can make their services better after being acquired by a rich company like Bitmain. I guess they'll be using the APIs in accepting payments as well for the miners.

Hi,

Please see the "receiving transactions" example in our blog post: https://blog.blocktrail.com/2015/02/your-free-decentralized-t-shirt/

Let me know if you have more questions.

After I read your thread and some quote from others members, today I was created wallet to Blocktrail and move my bitcoin balance from others wallet

Great!!!

https://i.imgur.com/b0eaTSs.png

I trying to make Blocktraill wallet. Why I not have receive transaction but my address is change? And in Blocktrail we can't make multiple wallet like coinbase or xapo?

Blocktrail provides HD (HD is short for Hierarchical Deterministic) wallets for your safety and privacy. You can create an unlimited number of addresses to help protect your privacy without the need for multiple private key backups. Our system will also generate new addresses for change and fund requests automatically.

HD wallets greatly improve your privacy by being able to generate new addresses whenever you send and receive funds, making your transaction activity and total balance very hard to track.


Please let me know if you have any questions.

I decided to give BlockTrail another shoot since BITMAIN took over ,  according to your Github repo :



I totally get how HD wallets works but I then saw the "Settings" tab and there is both my email and Username , will those information's be revealed for people ? (who use and who don't use BlockTrail) , If it's the case , is there is anyway to stay fully anonymous and continue to use your services ?

Great question Omega,

As bitcoiners ourselves we understand privacy.

Email addresses and usernames are never revealed. For increased privacy you can sign up to any of our services using a username instead of email address (via app) keep in mind however, that this is not recommended as you will not be able to perform a password recovery.

I'm definitely lost then , If Usernames & email addresses are not revealed then what is this ?

https://www.blocktrail.com/img/multidevice.jpg?v=51b6067ef1



It seems like Usernames & avatars are revealed , I basically want to know If we are two users using BLockTrail wallet , will they know and see my name as on the picture ? If it's the case , Is there is anyway to prevent that ?

The username and avatar in transactions list are shown only if both you AND your contact have each other in your phones address book, and only if you both have shared your phone's address book with Blocktrail.

We do this to enable users to send bitcoin to friends easily (great for new bitcoin users!), without needing to ask their friend for a receiving address each time. Since we discourage the re-use of addresses, Blocktrail's wallet automatically generates a new receiving address for your contact's wallet to receive the Bitcoin.

Please note that for user privacy, address book contacts that are shared with Blocktrail are sent encrypted before they reach blocktrail's servers, and blocktrail has no way to view your contacts.

Thanks

Oh awesome then, I thought It's sharing with anyone. Another question If you don't mind , is there is any plans to add the ability to sign messages at least ? that's probably one of the only few things that Blocktrail wallet needs

At the moment there is no efficient way to do this with a multi-sig and HD wallet such as ours.

If and when something does come along that will allow these to be done in an efficient manner for our users - then we would gladly add that feature.

Thanks for your questions Omega, we like hearing back from our users :)

If you guys need a translator to contribute in your Github projects then I will be more than happy to offer both French & Arabic translation . Let me know !

PM me if and when you have any ideas! :)

Blocktrail Set to Launch ‘Most Used Bitcoin App in Whole Industry’

I am looking at alternatives to the blockchain.info online wallet.

One thing I did not see addressed at blocktrail.com is whether or not I can import Private Keys (so as to "sweep" BTC from other wallets into a blocktrail one).

Is that possible and easy to do?

I couldn't tell you much about the phone version but for what comes to the online wallet , It's not possible as the wallet is Multi-signature , It's impossible to import or export any private keys.

Hey all,

Make sure to stay tuned as we will be giving away many other stuff!

BTC.com team

Hey OROBTC,

Good to hear that you are considering Blocktrail/BTC.com. We would suggest for you to just send all the bitcoin you intend to sweep to a Blocktrail/BTC.com wallet.

Blocktrail wallet is a multi-signature HD wallet, so recovering - or retrieving in your case - your bitcoins using a different wallet isn't as simple as just importing private keys, the wallet which would import the private keys would need to have some extra code to understand how the multisig HD is structured and the same for other multisig HD wallets (because they're all slightly different).

The reason why exporting private keys doesn't make sense anymore with most modern wallets is because they are HD (hierarchical deterministic)*, the fact that exporting private keys is such a horrible backup solution is actually the whole reason why HD wallets were invented.

* Source: https://en.bitcoin.it/wiki/Deterministic_wallet "A deterministic wallet is a system of deriving keys from a single starting point known as a seed. The seed allows a user to easily back up and restore a wallet without needing any other information and can in some cases allow the creation of public addresses without the knowledge of the private key."

I hope that answers your question. :)

Thanks and let me know if you have any other doubts or whatever.

Hello, since a  new address is generated every time a transaction is completed, is it possible to use the same bitcoin address for every transaction?

All generated addresses are your own , If we assume that you saved one of the generated addresses from the "Receive tab" in a text file , and you keep giving it each time to people so they send funds there ... you will receive the sent funds to your wallet without any issues.
This answer is valid for every HD wallet out there and not only Blocktrail btw.

Alright, thanks for that Omega!

Hello,

Yes you can use the same bitcoin address for every transaction. We don't recommend it though.

Blocktrail/BTC.com provides HD wallets for the safety and privacy of our users.

after read your reviewed, I try to opening account in blocktrail.com, but i want to know, why my address always change without receive bitcoin?

i want to ask where i can see private key
in blockrail wallet service
or not service about private key

It's an HD wallet like Multibit new version, to keep you secure and annonymous , a new address will be generated for every new transaction. (If someone send you funds to one of your old generated addresses then you still will receive them btw)



You can 't , at least not for the moment. Keep in mind that this is a Multi signature . See here FAQ for more info : https://www.blocktrail.com/faq

That's how HD wallets work, they are much safer than just using one wallet address! You can always reuse one wallet address if you like.

I read somewhere that blocktrail.com is bought by BITMAIN now  so will there be any changes in agreement with customers/users?

I have made updating bloctrail.com to BTC.com in my App android because of there is announcement via email and everything went fine and clear. I think you must try and we can make discussion about it.

Hi ,

I switched to BTC.com as the email requested to but It seems like there is something wrong, I received some bitcoin and when I click "see on btc" on the transaction details here :

https://i.imgur.com/Faacnak.png


I'm getting redirected to this NotFound page : https://btc.com/notfound
As you can see on the details , confirmations number is correct and the transaction shows without issues on blockchain.info  
TX ID If you want to take a closer look : 81acc5f6075d425f5f4a1ae75cbae919fa5737a5e72a5f359421fd4ce12485ea

EDIT : "Received from" is also bugged as It should show the bitcoin address you receive bitcoins from.

hello in blocktrail com use service private key for client or not
i can't see privat key in blocktrail

You can't get your private keys as It's a multi-signature wallet otherwise, It wouldn't make much sense to hold both private keys. But you are still the owner of the wallet , which means Black trail couldn't spend anything without you however If Blocktrail goes down for one reason or another you could restore your wallet .

If Blocktrail is ever unavailable you are always able to restore your wallet using the Blocktrail backup recovery document. This document is not specific to Blocktrail, and can work with Bitcoin-core directly.


More on the FAQ : https://www.blocktrail.com/faq

Is anyone else running into sync programs right now?

We're not seeing our wallet balance updated, and when attempting to send coins we get the "Input not found" error.

I'm glad we got that working for you, thanks for your patience.

Blocktrail.com's explorer is buggy. I recently got a transaction of 0.3BTC into my wallet, and after it confirmed, Blocktrail.com still showed that there was an unconfirmed transaction of 0.3BTC, and showed my balance +0.3BTC.

https://i.imgur.com/wFkP17S.png

There are also times when it doesn't shown an unconfirmed transaction in the transaction tab even though if you open the transactions tab, it is shown.

Thanks omega, sending to devs.

Use the BTC.com (http://www.btc.com) block explorer ;)

Can i have any guide on how to setup blocktrail php sdk on windows xampp server to test? I have tried several times using composer as suggested in github but it seems not working. I am getting vendor/autoload.php not found message. If anybody can give link to step by step guide on how to setup this, i will be thankful.

Would you be able to add a function that allows people to sign a message from an address that we own? I'm hoping for something like that since we can already verify messages.

I already asked this question like a month ago , and It seems like It won't be possible , at least not with the current wallet (that have both HD & Multi-signature) because I think that signing messages will give you both keys which won't make sense since you should control only one key , either that or It will require much work. => https://bitcointalk.org/index.php?topic=756279.msg15930072#msg15930072

You can check it on our new sign up page for the wallet. https://wallet.btc.com

Hello.
I'm using blocktrail API on my website, and most of the time it works smoothly. But sometimes the blocktrail API just sending the signal 10-30 minutes later.
In our site the deposit needs 1 confirmation to appear in the balance, but sometimes it only appears after 3 or 4 confirmation. I don't have an idea what is the problem, but I'm sure it's in the blocktrail API. I would really appreciate your help. Thanks.

Hello,

I have sent this to the dev team i will update you through PM. Thank you

Hi,

I'm planning to setup a site to allow registered users create their wallet through blocktrail API, is this possible? Can I host a web app that provide blocktrail wallet to each user that signup to my web app? if so how is the password handled? would it be the same as their logins on my webapp, or a different one and will only be triggered when they need to transfer funds to another bitcoin wallet?

We currently don't have a secure way for your users to create a wallet, we're working on a new backend system and plan to add oauth support when we switch to the new system.

I was checking your Android wallet and I must say that It both looks and works as should be. I can't seem to understand what is th "PROMO Code" thing for ? https://lh3.googleusercontent.com/O7prN2Fxd8vwvsISVfT7xkAhLgF9xNGYq66cbrNkafQCM4fHIk34Yk5-HJOgCPHw0bw=h900

---

And so I don't forget ,thanks for the BTC.COM T-shirt . It took sometime but It arrived a few weeks ago ! ;D

Happy to hear you like the app!

The Promo Code section is used occasionally for campaigns and contests to reward users with a code a small amount of BTC

Hi and thanks for responding guys , while comparing both the web and mobile app , It seems like you still didn't fix the bug in the web from the last time (when I reported it) :

https://i.imgur.com/urtQxZa.png


This feature works just fine in the mobile and you can clearly see from to where the transaction got sent or from where It got received while in Web It only state "received bitcoin" .

Fixed, not sure how it got through if you reported it, but I also don't recall a report of it (which could still be my mistake xD)

will be in the next release / deploy!

It's being sometime since I reported it and It wasn't you who answered me , It was neutraLTC and he told me he will send the issue to the developers . anyway thanks , happy It got fixed.  ;D btw , shouldn't the PROMO code thing be available in web version too ?

I have a doubt. Is this wallet is like coinbase? i mean in coinbase if we do any transaction there is no fee. Is this wallet also has the same feature?

no, this wallet is absolutely not like Coinbase.

Coinbase is what we call a "custodial wallet", a wallet that owns your bitcoins and will (most of the time) send those bitcoins to other people when you ask them to.

Our wallet (and all other "non-custodial wallets") will make sure that at all times YOU own your bitcoins, we don't have access to your bitcoins and you have the means (a backup of private keys etc) to take your bitcoins out of the wallet even when the wallet provider (us) would want to deny you access to it.
The service that our wallet provides is merely making the process of you using your private keys to send and receive bitcoins easier.

Because the nature of how custodial wallets own your bitcoins they can send bitcoins to other people who use the same wallet provider without having to an actual bitcoin transaction, they can just do -balance and +balance in their database in that case.

non custodial wallets can't do this because the bitcoins need to be moved from your address to the other persons address, so it always requires paying the transaction fee to the miners for the bitcoin transaction.


A good way to seeing the big difference between the 2 wallets is also that we can't help you recover your wallet if you've lost both your password and your backup document, because there's no way we can ever touch your bitcoins, only you can with either your password or the information on the backup document!

I am not able to signup to create a new wallet.  Is this wallet still working?

It is , Blocktrail switched to BTC.com recently and you can make a new wallet from here https://wallet.btc.com/#/setup/register just make sure to make a backup of the PDF file that they give you , that could be useful If something bad happens and you want to recover your wallet.

As OmegaStarScream explained we've rebranded the wallet to BTC.com but under the hood it's still the same technology.

If you're having any issues feel free to contact support@btc.com (or support@blocktrail.com) so we can help you resolve them.

https://wallet.btc.com/#/setup/register   is  not loading .

It's taking a little long to load but the site is loading just now. Maybe you have a problem woith your internet or maybe your browser. Check your connectiomn first or change browser if it still not loads then maybe try using a different connection.

If by "not loading" you mean you have the three colors but the form never shows up then , I used to have this problem in several sites (including this one) and I usually fix it by switching to another browser or by clearing the cookies and cache of the browser .

To keep this topic clean of too much noise, could you contact support@blocktrail.com or PM me with a screenshot of the page not loading with the "Developer Console" open? (hit F12 to open the tab with the developer tools and then click on "Console") 

long time no go blocktrail wallet, and it was in acquisition by bitmain:

Welcome to your new BTC.com Wallet by Blocktrail

Blocktrail has been acquired by Bitmain, and our services are now offered at BTC.com!

Thank you for being a loyal Blocktrail user! We look forward to continue to deliver you the most powerful Bitcoin wallet as BTC.com
Read the annoucement On our blog

I very like with this announcement, I sure this acquisition reinforces the wallet.

Is your mobile app from google play supposed to push notifications when we receive bitcoins because I'm not getting any, If not , then It would be really helpful If you could implement it so the app works in the background and give notifications when needed. If funds for example moved from your wallet from another device , when you receive BTC etc..

I'm trying to create a wallet blocktrail, but that makes me confused, why the address always changing while not accepting payment? Can we always use one address only?

Its normal that It makes a new address each time , Its an HD wallet and this is for your privacy. Using the same address over and over is not recommended but Its possible to do and you will receive your money.

This is a great suggestion, I want that as well. You are in luck because this is in the pipeline/roadmap coming to your bitcoin wallet soon :)

I think that if transformed after received the payment such as the Xapo or Coinbase, whether in this wallet where we can find the private key? Although already in the acquisition of Bitmain but if the hack of course we need the private key.

Its a multi signature wallet , giving you the ability to control both private keys wouldn't make any sense , nothing is stored in their servers as well so even If they get hacked there is nothing to be worried about.
If it ever happens and the service goes down for one reason or another then you could recover it[1][2] using the documents they gave you when you first installed the wallet.

Thanks again Omega,

Everything Omega wrote is correct.

by the way, we have a new thread, please use the new topic thread instead of this one -> https://bitcointalk.org/index.php?topic=1572823.0

Thanks!

Just thought I'd share. I did a new video tutorial on how to setup Blocktrail API with the nodejs sdk.

https://www.youtube.com/watch?v=bH1LvtV5Wvg

Nice one man! Will share it :) Thanks!!!

So btc.com only acquired the consumer wallet portion of blocktrail?  Is the developer blocktrail wallet API going to stay blocktrail, or is that going to get picked up by btc.com as well?  Personally I think the developer wallet API is the better service. There aren't that many options for wallet APIs out there, blockchain, blockcypher and blocktrail. I don't include coinbase or bitpay in the mix since they require intense screening to use their wallet API.

It is all going to go under the btc.com banner sort of speak, but nothing will change. Actually, things we be getting added and we intend to continue to improve the API service.

Thank you for the compliments, we appreciate it.

I need formulations of API curl:
- Create wallet.
- Transfer Bitcoin.

there are better examples

Everything you need can be found here: https://www.blocktrail.com/api/docs (https://www.blocktrail.com/api/docs)

I made a thread about your transaction accelerator until a user brought to my attention that you are only accepting credit cards through Stripe, why not accepting bitcoin? because It make no sense for a bitcoin service to accept something else or everything else except bitcoin in this case..

Can you point me to the thread please? and post this on our other thread please omega, thanks :)

Hey guys! Starting with Blocktrail Ruby SDK - https://github.com/yunixon/blocktrail

The features is simple. I thought this was a nice wallet because it's already taken over bitmain, but that makes me less like is transfer fee was 2 times greater than blockchain.

How i can use blocktrail on python
???? method init_wallet dont work in official python library

send an email to support@btc.com if you have any issues, thanks :D

Something is wrong by any chance? I just sent some funds to my other wallet using BTC.com web wallet, the fees are more then huge. It took 0.0045 BTC and that's about 5.19 USD with the current rates, I know It's based on transaction size but I'm sure It's not supposed to be that big unless the service is taking some fees too.

We are not taking any fee's. It's 100% based on size, if you want to pay a lesser fee you can login to your webwallet here -> wallet.btc.com (http://wallet.btc.com) and click on low priority fee, your fee will possibly take longer to confirm.

Hi guys,

I have a blocktrail.com developer account and there is a sending limit on the wallet of $35 how do I raise this limit anyone ???????

I urgently need to sort this out.....

send an email to support@btc.com

We where using the wallet interface to send out the funds to another address,
when we tried to send out any amount close to the balance of the wallet which was $100 USD and it
would not let us do this.

At the end we chose the max amount option on the send funds page, which let us
only send $43 USD and charged us a crazy transaction fee of $52.79 here is the link to
the transaction.

https://blockchain.info/tx/66609e48579c65fa500a31f1322ebc9cba8351729c25da92a9e5ffc12fc6d560

Could you please help us to lift sending funds limit to unlimited on our account if there is such setting it should be visible but its not.

I also sent an email to Re: devs@blochtrail.com

The wallet is working properly, it was a blockchain load issue.

All of a sudden the API is not working any idea what is going on?

This is what i'm getting.
