Today we’re announcing a new developer tool in beta: our multi-sig API.
We’re still working on a great consumer interface around this, but for today we’re releasing it to developers only.
Does this put me in control of my Bitcoin?
Yes. When you go and create a multisig account, you provide the extended (BIP32) public keys, which only enable us to create new receive addresses for your convenience. Only you have the extended private keys that can sign transactions and move bitcoin out of these addresses.
