Hi RGBKey,
I work for GreenAddress.it
If you want to try it, you can use the
https://test.greenaddress.it/faq testnet version with the testnet faucet.
If you do test it, please don't forget to send back the test coins to the faucet.
At the moment, while the site is up and most functionality is there and works the functionality related to presigned nlocktime transaction is not live yet, meaning that should we disappear you won't have access to your wallet unless we release our private key. This doesn't mean that we can take the funds, just that you wouldn't be able to take them if we are down.
With nlocktime presigned transaction even if we disappear you won't lose your coins, you will just have to wait for an expiry period of your choice.
If you want to try our prod version feel free and we would love any feedback you may have.
To be on the safe side, limit yourself to small amounts of btc until we provide nlocktime presigned transactions and the service is more established.
Thank you!
roslinpl, do you have any feedback ?
