answer context
How does x402 settle reader payments on Arc — exact scheme vs Gateway-batched?
x402 settles reader payments on Arc through two distinct schemes. The 'exact' scheme settles signed EIP-3009 USDC authorizations directly on Arc as a single USDC transfer, making the reader's debit a verifiable on-chain transaction. The Gateway-batched scheme pools multiple signed authorizations together for gasless sub-cent settlement, with payments referenced by a Circle Gateway payment id rather than individual Arc transactions.
Open answer evidenceDirectly answers the question: explicitly contrasts 'exact' scheme (single Arc USDC transfer) vs Circle Gateway-batched scheme (pooled authorizations, gasless sub-cent settlement). Core source.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.
