  • check_approval

    Check how much of an owner's ERC20 token a spender is approved to move (allowance). Flags UNLIMITED approvals — the #1 wallet-drain vector. Call this to audit existing approvals or before signing an approve(). Pure public RPC, no signing.

  • check_contract

    Pre-interaction risk check for an EVM contract/token address. Returns: is-contract vs EOA, EIP-7702 delegated-EOA detection, upgradeable-proxy detection (EIP-1967 + legacy), ERC20 metadata (name/symbol/decimals/totalSupply), and a risk score with actionable flags. Call this before approving, swapping, or trusting a token. Pure public RPC, no signing.
