SignBit

Bitcoin multisig, made easy.

Split your Bitcoin across several keys, held by you, your family, people you trust, and us if you want us. Spending takes more than one, so no single key is a single point of failure. We can never move your coins on our own, and you can always move them without us.

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