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. Instead of settling each authorization directly as a single on-chain transaction on Arc, 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.
Open answer evidenceExplicitly compares x402 settlement schemes on Arc, including Circle Gateway-batched scheme for gasless sub-cent settlement. Directly answers the question.Seed/demo content from Payments Protocol Notes. Title: x402 Settlement Schemes on Arc. Excerpt: x402 turns HTTP 402 into a real payment step: a resource returns payment requirements, the client signs an EIP-3009 USDC authorization, and the server settles it. The 'exact' scheme settles that authorization directly on Arc as a single USDC transfer, so the reader's debit is a verifiable on-chain transaction. The Circle Gateway-batched scheme instead pools many signed authorizations for gasless sub-cent settlement, referenced by a Gateway payment id rather than one Arc tx.
