Two rails. x402 pay-per-call settles in USDC on Base mainnet. The BYTE Library contracts and the EIP-712 PayloadAttestation domain are anchored on Arbitrum Sepolia (chainId 421614) — a fixed signing namespace, with the mainnet anchor pending an external audit. No token; no external-traction claims.
