Sub-claim "USDC enables instant on-chain settlement due to its design a…": 90% covered by S1 — S1 explicitly states USDC is a fully-reserved dollar stablecoin that settles peer-to-peer onchain in seconds. It directly covers the design (fully backed, dollar-pegged) and the instant settlement feature. The audited aspect is implied by 'fully-reserved' but not explicitly mentioned, hence not a perfect 1.0.
Sub-claim "Instant settlement suggests USDC leverages blockchain techno…": 100% covered by S1 — S1 directly states USDC settles peer-to-peer onchain in seconds and removes multi-day delays of card networks and ACH, explicitly contrasting with traditional banking delays. It also mentions 'final and programmable' settlement, confirming immediate finality.
Sub-claim "The capability for instant settlement indicates stablecoins …": 70% covered by S1, S3 — S1 discusses machine-to-machine commerce and removing counterparty risk, which relates to efficiency. S3 mentions Bank of England testing stablecoins for cross-border finance, linking to cross-border payments. However, explicit mentions of liquidity enhancement and DeFi are not strongly covered in the gathered sources.
Sub-claim "The focus on USDC's instant settlement implies it addresses …": 80% covered by S1 — S1 highlights speed (seconds vs. multi-day delays) and programmability, addressing limitations of traditional systems. Transparency is implied by 'onchain' settlement, but explicit comparison to other stablecoins is not present, slightly reducing coverage.
All claims have coverage at or above 0.7, which is adequate. No claim is below 0.5. While some claims could benefit from additional sources for fuller coverage, the remaining budget is small (0.02) and the skipped sources are low-priced but mostly not directly relevant to the core claims about USDC's instant settlement and its implications. The most relevant skipped source (e.g., 'Stripe Blog — Why global workers are driving demand for stablecoin payouts') is cheap but would not significantly increase coverage for the specific claims. Thus, it is frugal to stop here.

Final coverage assessment — The gathered sources provide strong, direct support for the first two sub-claims, covering USDC's design and the blockchain-based instant settlement. The third sub-claim is partially supported by a source mentioning cross-border use cases, but lacks explicit DeFi and efficiency details. The fourth sub-claim is not directly addressed; sources describe USDC's capabilities but do not contrast it with limitations of other stablecoins or traditional systems. The coverage is sufficient to answer the main question confidently.
