| Tool | Description | Behaviour |
|---|---|---|
| check_signature | Call BEFORE your agent signs or sends anything from a wallet. Decodes a transaction, an EIP-712 typed-data request (Permit, Permit2, EIP-3009 USDC authorizations, Seaport orders), an EIP-7702 delegation or an x402 payment (402 terms + payload) into plain English and returns SAFE / CAUTION / DANGER with risk flags (unlimited approvals, setApprovalForAll, fake USDC domains, x402 overpay or wrong payTo, OFAC SDN counterparties). Free preview tier (offline). The paid x402 endpoint /v1/check adds reasons, on-chain facts (spender is a wallet or contract, token metadata) and an eth_call simulation. | Read-only |
