The android app looks sweet, can't wait to try it out!
New Android app coming!
Click to see a short demonstration with a (optional) Trezor!
Want to try it now?
The app is actually available in early Beta for both Testnet and Mainet on a G+ community (requires to join the community to download the app)

So not been bias - greenaddress.it would be a safer option then say blockchain.info
As a mobile wallet ?
I am guessing nothing is 100% but ATM green doesn't have any known flaws ?

Technology-wise, they check off a number of boxes which Blockchain.info misses.
I don't think they have any black marks in their history (BC.i has a number of them), but they're also much younger than BC.i. Short of an independent audit... it's awfully hard to say.
Having said that, they are the mobile wall that I've chosen to use, so I at least think that they're a safe option.
If you do go with them, please be certain to:
- Write down your "mnemonic" as soon as you can. It's your backup, your password (PIN) recovery, and it's the only way you can log into your wallet from new devices. Don't save it to your PC (or learn how to use strong encryption if you must).
- Don't be afraid of using the PIN quick login option, it may seem like weak security but it's actually quite strong (and convenient). (If you enter your PIN in wrong just 3 times, it becomes useless and you'll need your mnemonic which you wrote down earlier.)
- Enable email notification for both inbound and outbound notifications. Each email notification contains a special recovery file which you'll need should GreenAddress ever disappear from the net (heaven forbid, of course).
- If you intend on using GreenAddress from a desktop, enable two-factor authentication. For a mobile, I'd be less concerned about two-factor.
That's my 2 satoshis...

GreenAddress uses RFC 6979 (deterministic signature) on all signatures (including hardware wallet like HW1) and uses only secure RNGs.
If a secure RNG is not available the platform is simply not supported.
All client code is open source (https://github.com/greenaddress) and feedback is welcome!

Sorry but any one that would be using your wallet are Noobs , why else would they not be running there own client on there own PC
so could we please get a Noob friendly answer ?
i am confused with all the blockchain.info talk out there
There are two ways of creating a bitcoin transaction. The (generally considered older) way requires a very secure RNG (an unpredictable random number generator), and for this reason it's considered a bit more risky. This is the method that Blockchain.info uses, and a recent change inadvertently broke their RNG for a little while.
The other way is what tryexcept mentioned -- it doesn't need any RNG for creating a transaction, and is generally considered safer (although since it's also newer, not every wallet uses it). It's also much easier to write tests for, if the developers use an automated testing tool to make sure that no bugs creep in.
(There are other ways too, but they're worse than the methods above, so they're rarely used.)
(You do still need a good RNG when you first create your wallet though.)

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

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

Blockchain.info is a strictly non-BIP32 wallet (an older method of creating addresses which requires frequent backups), and with the exception of vouchers*, GreenAddress.it is a strictly BIP32 (newer backup-friendly address creation) + multisig (much better malware protection vs. non-multisig wallets after enabling two-factor auth) wallet. There is no way to import/export between the two of them. If you'd like to switch from one to the other, you'll have to send btc from one to the other and stop using any old addresses (or continue to use both).
* Although I think you could technically create a voucher at GreenAddress and import its private keys into Blockchain.info, I have no idea why anyone would ever want to do this....
I tried several ones, including screencapturing its QR-code, but none worked.
If anyone find a way plz post it.
If anyone find a way plz post it.
I see that Blockchain.info is giving different options from the export function:
- Base58
- Bitcoin-Qt Format
- Base64
- Hex
- Leave Private Keys Encripted
Did you try all of them?
I also found this:
https://en.bitcoin.it/wiki/Wallet_import_format
http://gobittest.appspot.com/PrivateKey (I'm not sure that this is secure)
Maybe there are some ways to convert at least one of the blockchain.info formats to the WIF format.

I just wanted to share this quick anecdote.
I've been using GreenAddress as my preferred mobile wallet for a little while now, and I've been quite happy with it.
I ran into a small issue on Friday that was preventing me from creating a transaction. It was easy to find a workaround though, so it wasn't tying me up. I did a little bit of troubleshooting, but eventually gave up.
I sent an email to their general support box on a Friday at 6pm (my local time) along with the steps to reproduce the issue, and I explicitly mentioned that it wasn't really affecting me, so it didn't matter how long it might take for a response.
To my surprise, I received a pretty detailed response back by 8am Saturday morning listing out a few different bugs (all relatively minor) that they had found and fixed, as well as an expected release timeframe for the updated version (about a week).
I just wanted to post here to commend them -- I was really impressed that they took the time to read my email and reproduce the issue, and that they got back so quickly (even though it wasn't a big deal to me). All this , and it's a free service.
So anyways, thanks for a great piece of software and a great service!
All the best,
Chris

Added support for manual fees (per tx or per kb) in advanced view.
Is NFC on ? In case it is can you try a generic NFC reader app to check if the problem is with the device or our app?
Try also rebooting the device just in case sometimes they get stuck.

sometimes they get stuck. The ability to load the Mnemonic from NFC is not there on my phone?
It's weird because I'm sure I used it before.
I figured this out. To load from NFC just place the phone on the NFC tag from the login page. My previous issue was that NFC wasn't working right on my phone.. I was placing the phone on the NFC tag on the greenaddress mnemonic login page, but the phone was not reading the tag It's weird because I'm sure I used it before.

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