Safe (Gnosis Safe)

Safe (formerly Gnosis Safe) provides multi-signature smart contract wallets for managing digital assets on EVM-compatible blockchains. The Safe Transaction Service is a REST API that tracks transactions submitted to Safe smart contracts, enabling off-chain collection of signatures, owner notification of pending transactions, delegate management, on-chain message signing, and token/NFT balance retrieval across 40+ supported networks including Mainnet, Arbitrum, Optimism, Polygon, Base, Gnosis Chain, zkSync, and testnets. The Safe{Core} SDK (API Kit) provides a TypeScript client for the Transaction Service. Authentication uses JWT API keys with tiered plans ranging from a free Builder tier to high-throughput Scale plans.

Safe (Gnosis Safe) publishes 12 APIs on the APIs.io network, including 4337 API, about API, analytics API, and 9 more. Tagged areas include Multisig, Smart Contract, Ethereum, Web3, and Blockchain.

The Safe (Gnosis Safe) catalog on APIs.io includes 2 JSON-LD contexts and 1 Spectral governance ruleset.
