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. ## Related terms - [Wallet](https://fudfomo.co/glossary/wallet): An app or device that holds the keys you need to spend and receive crypto. - [Custody](https://fudfomo.co/glossary/custody): Who holds your crypto and the keys to it.
