I checked the google play and I saw an update , on the changelog It says : - new wallet encryption schema.
- auto-upgrade to new wallet encryption schema.
Is it something to be worried about ? I mean If you upgraded your encryption algorithms , does it mean that the old ones were weaker and we should change our passwords ? It also would be very nice If you could make the wallet checks for update when launching it because checking the google play often isn't something the average user would do. The upgrade is ofcourse improving the strength of the encryption, otherwise there wouldn't be much reason to upgrade it. However the strengthening is done on the encrypted primary key, to make sure it remains impossible to break the encrypted primary key, now and in the future (the scheme is now also future-proof, we can easily strengthen it more in 1~2 years). So there's no reason for you to change your password, it's not your password that is ever at risk. I'll add it to our feature requests to have a way to prompt users that there's an update, good idea! |

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. is not loading . 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") |

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. |

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! |

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) :
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! |

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,
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. |

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 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™.
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 |

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.
Regards,
Ruben
CTO, Blocktrail

I might have found another bug with your signed message verification. The following sign message was recently posted -----BEGIN BITCOIN SIGNED MESSAGE-----
This is harizen from bitcointalk.org. Today is February 1,2016.
-----BEGIN BITCOIN SIGNATURE-----
1BzFQocxr7QABTpwGz6o9Dsb6tPpBqbWZ8
HyEuQEIIi5KS0dqyCaIWh6a5A3wIMFqkSEehuNa7jOUZTSyLa08czuASi5RUcj78hPI5PMNec0w6XhzflMbFNcM
-----END BITCOIN SIGNATURE-----
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, $ bitcoin-cli verifymessage "1BzFQocxr7QABTpwGz6o9Dsb6tPpBqbWZ8" "HyEuQEIIi5KS0dqyCaIWh6a5A3wIMFqkSEehuNa7jOUZTSyLa08czuASi5RUcj78hPI5PMNec0w6XhzflMbFNcM" "This is harizen from bitcointalk.org. Today is February 1,2016."
error: {"code":-5,"message":"Malformed base64 encoding"}
$ bitcoin-cli verifymessage "1BzFQocxr7QABTpwGz6o9Dsb6tPpBqbWZ8" "HyEuQEIIi5KS0dqyCaIWh6a5A3wIMFqkSEehuNa7jOUZTSyLa08czuASi5RUcj78hPI5PMNec0w6XhzflMbFNcM=" "This is harizen from bitcointalk.org. Today is February 1,2016."
true
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. |

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" Any idea what thats about? "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"
Cancel
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. |

One more thing came up regarding your "Verify Signed Bitcoin Message" here -> https://www.blocktrail.com/BTC?verifysignedmessage=1Someone staked the following message here -> https://bitcointalk.org/index.php?topic=996318.msg12567926#msg12567926-----BEGIN BITCOIN SIGNED MESSAGE-----
I am otterboxed on bct.org, today @11:53 pm UTC on 9/30/2015.
-----BEGIN SIGNATURE-----
1oTTeRv4orMpeeiN8fDr1jN6ZkMrzohjD
HDI/nQ+rf7mtw99fe7dF3iFfHYMtBwcMiSJlzPgf6/79RbzdbJ+z5eHfSHOBsqBor6vv4u1s2WyasnJ3L3fV5/g=
-----END BITCOIN SIGNED MESSAGE-----
Note the trailing space at the end of the message, the @ is also uncommon. Regardless it does not verify. Fixed, the frontend code was trimming off the trailing space at the end! |

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). |

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

I've created a small NodeJS script that uses the Blocktrail API (SDK) to loop over the WIFs that have been published (manually copy pasted them into a list) and fetch their info, see; https://gist.github.com/rubensayshi/5f939d2de23071b85432WIFs 472 addrs 472 addrs with balance 403 received 14.69008000 balance 11.09027000 unconfirmed balance -5.68942000 utxos 1,109,027 utxos size 158,590.861kb There is an error

awh yea, had to bump the version of the NodeJS SDK, it didn't have that endpoint added to it yet :/ (done now) |

I think this is worse than the stress test... my electrum will not sync. BC.info is practically being DDOS by everyone trying to grab coins.
Even attempting to send it as a raw transaction is difficult as these addresses are full of dust (hundreds of tiny inputs).
This is insane!
are you trying to load these PKs into electrum or is electrum slow in general because of the TXs on the network? |
