How does Circle Gateway batch nanopayments on Arc for creators?

Circle Gateway batches nanopayments on Arc by pooling multiple signed EIP-3009 USDC authorizations, which are referenced by a Gateway payment ID rather than settled as individual on-chain transactions. This batching approach enables sub-cent payments to clear without incurring per-payment gas costs for creators.
