Copay


Copay is a true bitcoin wallet, not an account service. Secure your personal funds with multiple signatures, or just one.

Take security into your own hands and avoid trusting third parties with your savings. Like a joint-checking account, your Copay wallet can have multiple users. To send money, the group approves each transaction.

Copay is one of the first bitcoin wallets to support the full Bitcoin Payment Protocol (BIP 0070-0073).When you send money to a Payment Protocol-enabled merchant, Copay securely verifies that your payment will go to the right place.

The first bitcoin wallet to bring testnet support to both iOS and Windows Phone. Not only is the Copay app open source, the server is too.
