Re: Android App Development - Testing the waters

I wanted to see if there was any demand here for work that would be paid using bitcoin.

There's an opportunity for someone to build a standalone app to redeem private keys.

All the app (or mobile-enabled web app) needs to do is simply let you scan a QR code with a private key, and then scan the QR code of the destination Bitcoin address (or allow entry of the bitcoin address / paste from clipboard).

From there the app needs only to send an API call to Blockchain.info:

I have been meaning to add this ability to the blockchain.info API for a while. You can now replace the guid in the send api (https://blockchain.info/api/api_send) with a Hex encoded private key.

$address = destination bitcoin address.
$amount = amount to send in satoshi.

(Well, technically two calls, one to get the unspent balance and the second call for the spend transaction.)

This could be a pretty easy app (or mobile-enabled website) to build. To see how a mobile-enabled website can do a field for scanning via a QR code, see EasyWallet.org' site:

I'ld love to see someone build this capability for mobiles.
