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)

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

Wallet: Android

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

Code:

Scanning failed: TypeError: Cannot read property '1' of null

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

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 .

What about my query ?

Could you please confirm whether the following configuration on a shared hosting is enough to use blocktrail API in PHP environment?

PHP 5.4+
ext-curl
ext-json
ext-gmp
ext-openssl
ext-mcrypt

I have sent this to the dev team.

Any feedback from the dev team regarding this?

Have you tried following the README?

The SDK requires PHP 5.4+ and the Intl, GMP, BCMath and MCrypt PHP extensions.

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.

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

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

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™.

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.
