## Definition

Multi-sig is short for multi-signature. It is a setup where moving funds out of a wallet requires approval from several keys, not just one. A common pattern is two-of-three or three-of-five.

Multi-sig is widely used by companies, DAOs, and serious individual holders. It removes the single point of failure of one private key, at the cost of slightly slower workflows.
