Optimism

Optimism runs LOPW through the shared EVM binding: Solidity contracts, EIP-712 typed data signed with secp256k1, native USDC with 6 decimals, Chainlink feeds for P6 and x402 exact with EIP-3009. OP Mainnet and OP Sepolia share the OP Stack with Base, so the binding behaves identically; only addresses and chain ids differ.

Oracle note

P6 terms on Optimism name a Chainlink AggregatorV3Interface feed and its pair label as bytes32. The seller cites the roundId it used; the validator reads getRoundData(roundId) on-chain, applies max_oracle_age to the round’s updatedAt, and proves a breach with the exact integer deviation test. Every feed address is verified on-chain (description(), decimals()) before use and recorded in deployments/<network>.json.
