Sub-claim "Stablecoins maintain stable value, reducing volatility risk …": 80% covered by S3 — S3 explicitly states that stablecoins like USDC are fully-reserved dollar stablecoins that settle peer-to-peer onchain, providing a stable unit of account for agents to reason about budgets. This directly supports the sub-claim about stable value reducing volatility risk.

Sub-claim "Micropayments require low transaction fees, which stablecoin…": 70% covered by S4, S2 — S4 discusses nanopayments with off-chain authorizations batched onchain, reducing per-transaction costs. S2 shows sub-second settlement on Arc, implying low fees. However, direct mention of stablecoins achieving low fees is implicit; more explicit coverage would improve.

Sub-claim "Stablecoins enable fast settlement and programmability for a…": 90% covered by S3, S5, S2 — S3 mentions instant settlement and programmability. S5 describes x402 as a payment rail for agents. S2 provides sub-second finality. This sub-claim is well covered.

All sub-claims have coverage >= 0.7, which is above the 0.5 threshold. No additional sources are needed.

Synthesizing a grounded answer from 5 source(s)…

⚖️ Sources disagreed on Settlement time for x402 payments — S1 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time vs S2 x402 batched settlements on Arc finalize in roughly 180 milliseconds, not block-time-bound → trusted S2 (S2 provides specific measured data (median 178ms, p95 240ms) from testnet benchmarks, while S1 is a general statement about Ethereum L1 that may not apply to optimized layers like Arc.)
