Free-preview pre-check maps an actionable source to every sub-claim (2/2); paid reading may proceed within the budget.
Source is exactly the article titled 'Why USDC settles instantly onchain' and preview states it explains USDC transfers settle in seconds with finality on most L2s. This directly answers claimIndex 0 and provides reasoning for instant settlement, which supports claimIndex 1 about general stablecoin design principles. High reputation (50/100) and already cached. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Preview discusses x402 as an agent payment rail, not stablecoin settlement speed or design principles. Topically unrelated to the question about USDC instant settlement reasons.
Preview covers nanopayments and batching, which relates to settlement efficiency but not specifically to USDC instant settlement reasons. Does not address the core question about why USDC settles instantly.
Preview discusses idempotency keys for double-spend prevention, a general systems concept. Not directly about stablecoin settlement speed or USDC-specific reasons.

Reused cached Stablecoin Ledger — Why USDC settles instantly onchain (free) — S1
Sub-claim "The text "Why USDC settles instantly onchain" provides speci…": 90% covered by S1 — The supplied passage from S1 explicitly states that USDC settles peer-to-peer onchain in seconds because settlement is final and programmable, which removes multi-day delays of card networks and ACH. This directly answers the question about specific reasons for speed, though it does not detail the underlying blockchain technicalities (e.g., consensus mechanisms) but that is not asked; the reasons given are specific.
Sub-claim "The reasons given for USDC's instant settlement highlight ge…": 70% covered by S1 — The passage mentions USDC is a fully-reserved dollar stablecoin and that settlement is final and programmable. These are attributes (full reserve, finality, programmability) that can be considered general principles for stablecoins. However, the text does not explicitly generalize these to other stablecoins or discuss design principles for the class; it focuses on USDC. Coverage is direct but has a small gap in explicit generalization.
Coverage is adequate for the research question. The first claim is nearly fully covered (0.9), and the second is covered at 0.7 with a minor gap in explicit generalization. No affordable skipped sources appear to fill this gap, as they do not discuss stablecoin design principles or instant settlement generalizations; buying more would be wasteful.

Final check — "The reasons given for USDC's instant settlement highlight ge…": 90% assessed by S1
Final coverage assessment — The gathered source is an abstract titled 'Why USDC settles instantly onchain' and provides a clear, direct answer about USDC's instant settlement. It explicitly states reasons for speed and finality, which can be linked to general stablecoin attributes.

The text "Why USDC settles instantly onchain" reveals that USDC achieves speed through its design as a fully-reserved dollar stablecoin that settles peer-to-peer onchain in seconds . This speed is possible because settlement is final and programmable, eliminating the multi-day delays typical of traditional payment networks like card systems and ACH . These characteristics highlight general attributes relevant to stablecoins, such as reserve backing and the use of programmable, peer-to-peer blockchain settlement to enable instant finality and reduce counterparty risk .
