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.
