Sub-claim "Settlement latency reduces on-chain costs by batching transa…": 70% covered by S3, S5 — S3 provides evidence of batched settlements with sub-second finality on Arc, implying batching reduces on-chain costs. S5 discusses nanopayments settling in batches to reduce gas costs. However, the claim specifically mentions 'settlement latency' as a mechanism, which is partially covered but not explicitly linked to cost reduction in the gathered texts.

Sub-claim "Arc protocols reduce on-chain costs by enabling efficient da…": 40% covered by S3 — S3 mentions Arc's BFT consensus and sub-second finality but does not explicitly discuss data compression or aggregation as cost-saving mechanisms. The claim is partially covered by the implication of batching, but direct evidence is lacking.

Sub-claim "Settlement latency and arc protocols together minimize the n…": 30% covered by S3, S5 — S3 and S5 discuss batching and off-chain authorizations, which reduce on-chain operations, but the combined effect of settlement latency and arc protocols is not explicitly addressed. Coverage is low.

Claims 2 and 3 have coverage below 0.5. The most relevant skipped source is 'Distributed Systems Notes' (price 0.003) which likely covers consensus, replication, and possibly data compression/aggregation techniques. Other sources are either too general (Cointelegraph, CoinDesk) or irrelevant (gardening, retro gaming). Budget remaining is 0.02, so this source is affordable.

Filling gap — buying Distributed Systems Notes ($0.003)…

Synthesizing a grounded answer from 9 source(s)…

⚖️ Sources disagreed on Settlement latency of x402 payments — S1 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time. vs S3 x402 batched settlements on Arc finalize in roughly 180 milliseconds (median 178ms). → trusted S3 (S3 provides specific, measured data from testnet benchmarks (median 178ms, p95 240ms) and explains that Arc's BFT consensus delivers sub-second finality, while S1 is a general reading without empirical support. S3 is more specific and internally consistent.)
