Bitcoin custody where we hold a key, never control.

SignBit secures Bitcoin across multiple independent keys. You keep a key, we co-sign under rules you set, and a recovery key covers what happens if life gets in the way. We can never move your coins on our own, and you can always move them without us.

We are building it now. Back here soon.

Want to try it? The testnet demo runs on worthless test coins, so nothing you do there touches real money.
