Do you plan to make any other altcoin wallets?

No. It was built with just Bitcoin in mind. It could be modified, but the biggest challenge is finding a suitable API for the alt coin.

Apple announced this a little over a week ago (allowing apps that can facilitate payments).

They updated their review guidelines last week, but the wording wasn't clear if they would actually allow Bitcoin wallets in all countries. This shows that it can be done and it can be available to the entire iOS market.

I just got the email that Apple accepted CoinPocket into their App Store.  It is mostly the same as the HTML5 version (https://coinpocketapp.com) except for a few UI changes and of course a built in QR code scanner.

How about the
qr code scanner I am testing these days? Do you have any ideas about it? Or any good suggestion? Thanks in advance.


I'm not sure what you're asking. The QR Code scanner that works with Coin Pocket is called Scan Code https://itunes.apple.com/us/app/scan-code-qr-code-reader/id828167977?ls=1&mt=8.

New Updates!

https://btc.coinpocketapp.com
https://github.com/enriquez/coinpocketapp.com

* Access your private key in BIP38 format. Use it to keep a backup in case your browser data
* Sweep private keys. This makes using paper wallets easier.

Is there a particular reason why your QR scanner works only with iOS7+?

iOS 7 is the current version of iOS. Most users have it already, and it's a free update.

I'd recommend updating iOS if you do anything with Bitcoin. There are known vulnerabilities in older versions.

Is this app iOS-specific? I tried using it on Windows Phone, but it gives me an error about a secure random number generator nor being present.

Coin Pocket is not iOS specific, but it does have some browser requirements including a secure random number generator. The browser on a Windows Phone may have one that is compatible, but I'll have to research and test it out.

Hey Christian,

There are no docs, and it isn't using x-callback-url. I didn't know about that spec when I did Scan Code. Maybe for a future update...

You have the right URL to launch Scan Code.

Code:
scancode://scan?callback=myapp://some.callback/url/path

Scan Code will open the callback url while appending a `code` param

Code:
myapp://some.callback/url/path?code=urlEncodedQrCodeData

Your app can then parse the query string for the `code` param. I don't know how flexible Pythonista is, but you would need to hook into the AppDelegate's `application:openURL:sourceApplication:annotation`.

Let me know how it works out for you!

I guess, u may re-think this part. In general a bitcoiner does not own his coins, unless he owns the private key. Your project seems promising ...So I'm suggesting.

Thanks for the suggestion. Not giving the user direct access to their private key was a conscious decision.

I simply don't trust the user to be able to keep their private key safe outside of Coin Pocket and their device backups. They can do everything they need to do without seeing their private key. They can continue to use Coin Pocket and send transactions even if the server goes offline.

Coin Pocket is meant to be easy to use, so there aren't a lot of advanced features.

Hey, Mike ...nice app. Can u plz tell me, how come one person get to know the private key of his wallet from this app ?

Hi. Thanks.

There's no interface for the user to get their private key. Backups are done by backing up the device. Moving to another wallet is done by sending the Bitcoin.

[ANN] Launching Coin Pocket v1.0.0 - HTML5 Wallet with QR Code Scanner for iOS
by
enriquez
on 28/04/2014, 16:03:10 UTC
https://coinpocketapp.com

After 2 months of work, 120+ commits, and 11 pre-release versions I’m calling Coin Pocket ready for prime time.

Coin Pocket is an open source Bitcoin wallet that runs completely in the browser. This includes key generation, transaction signing, and storage. Block chain interactions are provided primarily by Blockchain.info with helloblock.io as a fallback.

I wanted to help out with Bitcoin adoption, especially with iOS users. I didn’t want to jailbreak , install profiles, or do any weird workaround. This is a legitimate approach using HTML5.

I also created Scan Code, a QR code scanner for iOS. A custom url scheme is used to launch Scan Code. After scanning, it immediately passes the data to a callback url. Coin Pocket integrates seamlessly with Scan Code to make scanning QR codes super easy on iOS.

Note: There is no service that backs up your private key. You are responsible for backing up your device and making sure Coin Pocket’s data is properly backed up with it. It is a known issue that updating iOS will delete Coin Pocket’s data. You will have to restore from a backup by resetting your device. I recommend moving your funds to a different wallet before updating iOS to avoid having to go through this.

Sounds good but there is still a problem with security ... you have to use online wallet.
But it is some method for iOS sad users.
Regards

Coin Pocket is as native as we can get on iOS without any weird workarounds. It stores the encrypted private key in the browser and it continues to work if the server goes down. I still wouldn't recommend storing a significant amount, just enough to spend with.

HTML5 wallets and QR Code scanning on iOS
by

on 25/04/2014, 19:18:45 UTC
I found a way to make QR code scanning easier for iOS users. Right now, most web wallets do QR code scanning by taking a picture and hoping that it is clear enough to scan. It can take a few tries if you don't get a good picture.

I came up with an iOS app that is simply a QR code scanner. It can be launched with a link that can specify a callback url which gets passed the qr code data after scanning.

The QR Code app is called Scan Code: https://itunes.apple.com/us/app/scan-code-qr-code-reader/id828167977?mt=8

It works with an HTML5 wallet I've been working on called Coin Pocket: https://coinpocketapp.com

Coin Pocket: HTML5 wallet + Native iOS QR Code Reader

https://coinpocketapp.com

Coin Pocket is almost out of beta. The first beta was released about a week ago. Since then there have been improvements to workaround Blockchain.info's API issues.

I'm going to give it more time before taking it out of beta, but until then I need feedback! Please test it out and break it. I also need people to review the code https://github.com/enriquez/coinpocketapp.com

I built Coin Pocket as a better alternative to other mobile wallets. I wanted something that looks good and is easy to use (especially with scanning QR Codes on iOS). This is an app you can recommend to new Bitcoin users.

...and it's back.

It's probably a good time to investigate other options or fallbacks. I've been keeping an eye on https://helloblock.io. I would run my own node, but I wanted to keep my costs down.

I have the same issue. My app stopped working as well.

We're not doing anything wrong, they changed something on their end. I'm trying to get in contact with them, but haven't heard back yet.

Anyone else using their API? Looks like they made an updated last night.

I'm getting a DDoS protection response instead of the data I need. This brought down my whole app Sad
