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 evidenceComprehensive explanation of x402 settlement including the Circle Gateway-batched scheme that pools signed authorizations for gasless sub-cent settlement. Essential context for understanding nanopayment batching mechanicSeed/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.
