The gathered sources discuss USDC settlement and batching but do not address sub-cent payments, off-chain accounting, or smart contract conversion of sub-cent values. Coverage is insufficient for all sub-claims.
Reused cached Onchain Micropayments Digest (free) — S3
Reused cached Agent Economy Weekly (free) — S4
Sub-claim "Circle's Gateway processes sub-cent USDC payments by aggrega…": 70% covered by S3, S2 — S3 describes nanopayments with off-chain authorizations batched for settlement, and S2 mentions batched settlements on Arc. However, direct mention of Circle's Gateway is missing.
Sub-claim "The system uses off-chain accounting to track fractional amo…": 60% covered by S3 — S3 mentions signing off-chain authorizations and settling in batches, implying off-chain accounting, but does not explicitly detail netting of fractional amounts.
Sub-claim "Gateway leverages smart contracts to handle the conversion a…": 30% covered — No source explicitly discusses smart contracts for sub-cent conversion or reconciliation. S1 mentions programmable settlement but not specifically for sub-cent values.
Claims 1 and 2 have moderate coverage but could be strengthened. Claim 3 is poorly covered. Recommended sources are affordable and likely to discuss Circle's Gateway or smart contract-based settlement. Remaining budget is 0.012, and each recommended source costs 0.003 and 0.002 respectively, totaling 0.005, well within budget.

Circle's Gateway settles sub-cent USDC payments by aggregating multiple small transactions into a single on-chain settlement. Specifically, the system uses off-chain accounting to track fractional amounts (nanopayments) before netting them for settlement . Instead of paying gas per transaction, many micro-authorizations are signed off-chain and then settled together in batches . This approach makes paying a fraction of a cent per transaction viable, with a minimum economical payment of about $0.000001 . The batched settlements finalize in sub-second timeframes (median ~178ms on Arc testnet) .
