Safe (formerly Gnosis Safe) is the most trusted smart wallet infrastructure for securely managing onchain assets. It is modular, programmable, and battle-tested — having processed over $1 trillion in volume and secured $60B+ in assets across 57M+ deployed wallets.
Key Features
-
Multisignature Wallet — Eliminate single points of failure by distributing access control across multiple owners. Set signing thresholds so no single private key compromise can drain funds.
-
Transaction Simulation — Scan and simulate transactions before they execute, giving you full visibility into what each transaction will do.
-
Spending Limits & Roles — Set daily spending limits, approval thresholds, and role-based access for team members.
-
Multichain Treasury Management — Invite team members to manage and track multi-chain Safe accounts together from a single dashboard.
-
Transaction Builder — Bundle multiple complex transactions into one signing step to cut gas costs.
-
Safe Shield — Built-in security layer with transaction guards, clear transaction insights, and a security hub for real-time threat monitoring.
Security
Safe is among the most audited and battle-tested smart contract systems on Ethereum. Its contracts are formally verified, fully open source, and audited by leading firms including OpenZeppelin, Certora, Ackee, and Runtime Verification.
Use Cases
- DAOs & Protocols — Securely manage treasury operations with multisig governance
- Teams & Organizations — Collaborate on financial operations with role-based access controls
- Power Users — Self-custody personal funds with recovery options and DeFi access
- Developers — Build on Safe's modular infrastructure using SDKs and APIs
Safe also offers mobile apps for iOS and Android, enabling transaction signing and notifications on the go.
Pros
- Eliminates single points of failure by requiring multiple signatures (M-of-N threshold) to authorize any transaction, with customizable owner configurations.
- Battle-tested with over $60B in total value locked and $1T+ total value processed across 57M+ deployed wallets.
- Smart contracts are formally verified and audited by top firms including OpenZeppelin, Certora, Ackee, and Runtime Verification, with an ongoing bug bounty program.
- Offers built-in transaction simulation, spending limits, role-based access controls, and a transaction builder that bundles complex operations to reduce gas costs.
- Integrates with 200+ dApps and supports multichain operations across Ethereum, Arbitrum, Optimism, Base, Polygon, and 10+ other EVM networks.
Cons
- Transaction delays can occur when waiting for co-signers across different time zones to approve and sign a transaction before it can execute.
- Limited to EVM-compatible chains, with no native support for non-EVM ecosystems like Solana, Bitcoin, or Cosmos.
- Steeper learning curve for new users compared to traditional wallets, requiring understanding of multisig configuration, owner management, and threshold settings.
- Smart contract wallet deployment and multisig transactions incur higher gas fees compared to simple externally-owned account (EOA) wallets.
- Requires careful management of multiple owner wallets and signing thresholds, which adds operational complexity for teams coordinating transactions.
