answer context
How does Tollgate settle reader payments on Arc via x402?
Based on the provided sources, specific details about how Tollgate settles reader payments on Arc via x402 are not explicitly documented in the purchased sources. However, the sources indicate relevant infrastructure components: Arc is designed for stablecoin-native settlement with USDC and sub-second finality, and Circle Gateway batches signed EIP-3009 authorizations so x402 payments can clear at sub-cent values without per-payment gas. These components suggest a framework for nanopayment settlement, but the sources do not contain explicit information about Tollgate's specific settlement mechanism via x402.
