settlement / verify
Reads the receipt of a transaction on Ethereum, Base, Base Sepolia, OP Mainnet, Arbitrum One, Polygon PoS or Avalanche C-Chain and compares it with what you expected to be paid. The comparison runs against the ERC-20 transfer events in the receipt, not against the transaction recipient, because in a token payment the transaction recipient is the token contract and never the seller.
