Industry-standard multisig smart contract wallet for Ethereum, requiring multiple signatures to authorize transactions for enhanced security. Originally developed by Gnosis in 2016 for their token sale, the project spun off in 2022 as Safe{Wallet} and Safe{Core}.

Now secures billions of dollars in digital assets across DeFi protocols, DAOs, and institutional treasuries. The programmable smart contract architecture provides advantages over hardware wallets by enabling custom access controls, spending limits, and recovery mechanisms. Widely adopted as the default treasury solution for Ethereum-based organizations.
