answer context

How does x402 settle reader payments on Arc — exact scheme vs Gateway-batched?

The purchased sources do not contain specific information about how x402 settles reader payments on Arc or details about an exact settlement scheme versus Gateway-batched approach. While the sources confirm that Circle Gateway uses batched EIP-3009 authorizations for nanopayments and that Arc provides stablecoin-native settlement with USDC gas and sub-second finality, they do not describe x402's integration, settlement mechanism, or comparative settlement schemes between these systems.
