Multisig accounts API

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.

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.

Learn how to use the new API in this tutorial.

Multisig accounts are considered an advanced feature and our API is currently in beta, so only use small amounts of bitcoin for the moment.
