answer context
What is Circle Gateway nanopayment batching on Arc?
Circle Gateway nanopayment batching on Arc is a settlement scheme that pools multiple 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, allowing x402 payments to clear at sub-cent values without incurring per-payment gas costs.
