What is Safe?
Safe (formerly Gnosis Safe) is the most widely deployed smart contract wallet platform, providing multi-signature authorization, modular extensions, and programmable transaction logic — securing over $100 billion in crypto assets across multiple blockchains.
WHY IT MATTERS
Safe is the gold standard for organizational crypto security. It's used by DAOs, protocol treasuries, venture funds, and enterprises to manage shared funds with multi-party authorization. The battle-tested smart contracts have been running since 2018 with an exceptional security record.
Safe's modular architecture supports extensions (called modules) that add custom functionality: spending limits, automated recurring transfers, and integration with external policy systems. This makes Safe adaptable to agent wallet use cases.
For agent wallets, Safe can serve as the governance layer. The treasury is a Safe multisig requiring human approval for large operations. Agent wallets are funded from the Safe with controlled amounts. Policy changes require Safe transaction approval from multiple signers.
HOW POLICYLAYER USES THIS
PolicyLayer can operate as a Safe module — adding programmable spending controls on top of Safe's multisig security. This combines Safe's proven custody model with PolicyLayer's automated, policy-based transaction validation for agent operations.
