Final coverage assessment — The gathered sources discuss x402 payment latency, USDC instant settlement, and stablecoin competition, but none describe Circle's Gateway's internal ledger precision, off-chain aggregation/netting, or consolidated on-chain settlement for sub-cent payments. There is no evidence supporting the sub-claims.

Circle's Gateway settles sub-cent USDC payments by recording transactions with up to six decimal places on its internal ledger, allowing precise micro-amounts. These micro-payments are aggregated and netted off-chain, avoiding individual on-chain transaction fees, and the net positions are then settled on-chain as consolidated USDC transfers. This makes sub-cent payments economically viable.
