Multisig

A smart contract wallet that requires multiple private keys to sign transactions before they execute — for example, 3-of-5 multisig requires 3 out of 5 keyholders to approve. Multisigs are used by DeFi protocols, DAOs, and high-value wallets to prevent any single point of compromise. Safe (formerly Gnosis Safe) is the dominant multisig wallet on Ethereum, used by most major DeFi protocols for treasury management.
