answer context
What is Circle Gateway nanopayment batching?
Circle Gateway nanopayment batching is a settlement scheme that pools many signed EIP-3009 USDC authorizations together for gasless sub-cent settlement. Rather than settling each authorization as a single on-chain transaction, the batched scheme references payments by a Gateway payment id, enabling x402 payments to clear at sub-cent values without incurring per-payment gas costs.
Open answer evidenceDirectly answers the question: explicitly describes Circle Gateway batching of EIP-3009 authorizations for sub-cent x402 payments without per-payment gas.
