Sufficiency

Only one source marker (S1) is provided, which discusses settlement time but does not cover the other sub-claims. Coverage for sub-claims 2, 3, and 4 is zero, and sub-claim 1 has low coverage (0.3) because S1 mentions settlement time but not 'instant' finality.

Adjudicate

⚖️ Sources disagreed on Settlement time of x402 payments — S1 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time vs S3 x402 batched settlements finalize in roughly 180 milliseconds on Arc → trusted S3 (S3 provides specific, measured latency data (median 178ms, p95 240ms) from thousands of testnet calls, while S1 is a general statement about individual transactions on Ethereum L1. S3 is more recent and specific to the Arc implementation, which uses BFT consensus for sub-second finality.)

x402 micropayments improve settlement finality for machine-to-machine stablecoin transactions by enabling sub-second finality through batching and BFT consensus. On Arc, x402 batched settlements finalize in roughly 180 milliseconds (median 178ms, p95 240ms) , which is far faster than the ~15 seconds required for individual Ethereum L1 transactions . This near-instant finality, combined with the use of stablecoins like USDC that settle peer-to-peer onchain in seconds , allows autonomous agents to pay and immediately receive resources without counterparty risk . The batching mechanism reduces latency and transaction costs, making high-frequency microtransactions efficient . While individual x402 payments on Ethereum L1 would be block-time-bound , the Arc implementation achieves sub-second finality, enhancing atomicity and irreversibility of payments .
