S1 strongly supports instant onchain settlement and the contrast with traditional card/ACH delays, but no source explicitly states that stablecoins are blockchain-based assets on public ledgers. S2 is about bond repo transactions onchain, not stablecoins. Thus the overall evidence is insufficient for all sub-claims.

Sub-claim "Instant onchain settlement distinguishes stablecoins from tr…": 100% covered by S1
S1 directly supports instant onchain settlement for stablecoins and contrasts this with traditional multi-day settlement, fully covering claims 1 and 3. Claim 2 is partially supported because 'onchain' implies blockchain-based assets, but the source does not explicitly mention public ledgers.
All sub-claims already well-covered (sufficiency passed with 0 gaps) — skipping re-evaluation to save latency.

Final coverage assessment — Source S1 directly addresses the article's topic, explicitly describing USDC's instant onchain settlement and its contrast with traditional systems. It supports the claim that stablecoins settle instantly onchain and that this distinguishes them from traditional finance. It also implies blockchain-based operation. Other sources are less relevant.
Synthesizing a grounded answer from 4 source(s)…
Verified — S1 supports claim 1 at 100%: “USDC is a fully-reserved dollar stablecoin that settles peer-to-peer onchain in seconds.”
Verified — S1 supports claim 3 at 100%: “Because settlement is final and programmable, it removes the multi-day delays of card networks and ACH.”

The article reveals that stablecoins can settle transactions instantly onchain, stating that “USDC is a fully-reserved dollar stablecoin that settles peer-to-peer onchain in seconds” . It also reveals that instant final onchain settlement distinguishes stablecoins from traditional financial systems, because “settlement is final and programmable, it removes the multi-day delays of card networks and ACH” . However, the source does not explicitly characterize stablecoins as blockchain-based assets operating on public ledgers; it only describes onchain settlement, so that specific subclaim is not supported by the provided source.
