No source explicitly describes Circle's Gateway or sub-cent USDC settlement. S5 discusses nanopayments and batching but not Circle's Gateway. S3 mentions Gateway-batched payments but not sub-cent. Coverage is low for all sub-claims.
Sub-claim "Circle's Gateway uses a mechanism to settle USDC payments in…": 0% covered — No gathered source mentions Circle's Gateway or sub-cent USDC settlement. S5 discusses nanopayments and batching but not specifically Circle's Gateway.
Sub-claim "The settlement process for sub-cent USDC payments involves s…": 0% covered — No gathered source describes any technical steps for sub-cent USDC settlement by Circle's Gateway.
Sub-claim "The Gateway system can aggregate or batch sub-cent payments …": 20% covered by S5 — S5 mentions batching micro-authorizations for nanopayments, which is conceptually similar to aggregating sub-cent payments, but does not specifically refer to Circle's Gateway.
All three sub-claims have coverage below 0.5. The remaining budget is $0.007. The two cheapest relevant sources (Stripe Blog at $0.002 and Coinbase Blog at $0.003) total $0.005, within budget. They may provide information on Circle's Gateway or sub-cent USDC settlement. Other sources are either irrelevant or more expensive.

The provided sources do not describe Circle's Gateway or its settlement of sub-cent USDC payments. However, related mechanisms for sub-cent stablecoin payments are discussed. Nanopayments achieve a minimum economical payment of about $0.000001 by signing off-chain authorizations and settling them in batches, avoiding per-transaction gas fees . For batched settlements on Arc (a BFT consensus network), finality is achieved in roughly 180 milliseconds (median 178ms, p95 240ms) . USDC itself settles peer-to-peer onchain in seconds with final settlement . These techniques could be applied to aggregate sub-cent USDC payments into a single onchain settlement, but no source explicitly confirms Circle's Gateway uses them.
