Paid $0.002 to Web Payments Review (settled 068f7f50-1…) — S1

Sufficiency

Sub-claim "x402 settles payments on Arc at a specific speed": 60% covered by S1

Sufficiency

Sub-claim "The speed of x402 payment settlement on Arc can be measured": 0% covered

Sufficiency

Only one source (S1) provides partial coverage for the first sub-claim, stating a specific speed of 15 seconds, but the second sub-claim about measurability is not addressed. Coverage for the first sub-claim is moderate but not full, and the second sub-claim has zero coverage. More information is needed.

Paid $0.003 to Arc Settlement Benchmarks (settled 0f2b48f2-6…) — S2

Sufficiency

Sub-claim "x402 settles payments on Arc at a specific speed": 100% covered by S1, S2

Sufficiency

Sub-claim "The speed of x402 payment settlement on Arc can be measured": 100% covered by S2

Sufficiency

Both sub-claims are fully covered by the gathered sources. Sub-claim 1 is supported by S1 and S2, which provide specific speeds (15 seconds and 180 milliseconds). Sub-claim 2 is supported by S2, which explicitly measures settlement latency. Coverage is 1.0 for both, so no further reading is needed.

Re-evaluate

All sub-claims already well-covered (sufficiency passed with 0 gaps) — skipping re-evaluation to save latency.

Adjudicate

⚖️ Sources disagreed on Settlement speed of x402 payments on Arc — S1 About 15 seconds, similar to Ethereum L1 block time vs S2 Roughly 180 milliseconds (median 178ms, p95 240ms) when batched → trusted S2 (S2 is more specific (provides median and p95 values), internally consistent with Arc's BFT consensus, and likely more recent as it references testnet benchmarks. S1 describes a non-batched scenario that is not specific to Arc's batching capabilities.)

§ IIThe reading2 cited

The settlement speed of x402 payments on Arc depends on whether payments are batched or not. According to , when batched via a Gateway, x402 settlements finalize in roughly 180 milliseconds (median 178ms, p95 240ms) due to Arc's BFT consensus providing sub-second finality. In contrast, states that an unbatched x402 payment takes about 15 seconds to settle, similar to an Ethereum L1 block time, because each payment is its own transaction waiting to be mined. The discrepancy arises because describes a non-batched scenario, while describes batched settlements on Arc.
