  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.
