answer context
How does x402 settle reader payments on Arc, exact vs Gateway-batched?
Based on the available sources, x402 payments on Arc leverage Circle Gateway's batching of signed EIP-3009 authorizations to enable sub-cent value payments without per-payment gas costs. Arc provides stablecoin-native settlement with USDC and sub-second finality. The Driplet implementation demonstrates x402 nanopayments settled on Arc with <500ms settlement times and payments as small as $0.000001 with zero gas. However, the purchased sources do not contain specific technical details distinguishing between 'exact' settlement versus 'Gateway-batched' settlement methods, so this distinction cannot be answered from the available information.
