answer context
How does x402 settle payments on Arc?
x402 settles payments on Arc through the 'exact' scheme, which settles EIP-3009 USDC authorizations directly on Arc as a single USDC transfer, making the reader's debit a verifiable on-chain transaction. Arc itself is designed for stablecoin-native settlement with USDC gas and sub-second finality.
Open answer evidenceDirectly answers the question: explains x402 settlement on Arc, EIP-3009 authorization flow, 'exact' scheme (single USDC transfer), and Circle Gateway-batched scheme. Core technical reference.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.
