Safe

Safe is a standard for programmable multi-signature smart accounts based on account abstraction (ERC-4337). The company says it secures over $100 billion in assets. It was founded in 2018 and is based in Zug, Switzerland, and Berlin, Germany.

Products Safe{Wallet} provides multi-sig management of accounts. The Safe{Core} account abstraction SDK includes Relay, Paymaster and Signers, and spending limits and modules let a team set rules for outgoing payments. It is described as the base standard for holding treasury USDT and USDC on EVM networks and for creating smart wallets without seed phrases.

Users and networks Target users are Web3 protocols, crypto treasuries, stablecoin neobanks such as Gnosis Pay, and PSPs. Safe works on Ethereum and 15+ EVM networks.

Model The open-source protocol is free, with an enterprise SDK for larger needs. Teams should clarify which SDK components carry commercial terms and how support is provided.
