The gathered source only discusses Arc's fast settlement latency but does not address Ethereum-specific mechanisms like state channels, probabilistic settlement, or HTLCs. Coverage for all sub-claims is zero.

Sub-claim "Nanopayments between autonomous agents can be settled trustl…": 30% covered by S6 — S6 mentions off-chain authorizations and batching, which aligns with payment channels, but does not explicitly discuss state channels or trustless settlement on Ethereum. No source directly addresses this sub-claim.

Sub-claim "To avoid waiting for block finality, agents can use techniqu…": 20% covered by S1 — S1 discusses sub-second finality on Arc, but that is a different chain, not Ethereum. No source covers probabilistic settlement or optimistic protocols for Ethereum.

Sub-claim "Trustless settlement can be achieved through cryptographic m…": 0% covered — No gathered source mentions HTLCs, multi-signature escrows, or any cryptographic mechanism for trustless settlement.

All three sub-claims have low coverage (<0.5). The remaining budget is 0.017. The cheapest relevant sources are Stripe Blog (0.002), Coinbase Blog (0.003), and Distributed Systems Notes (0.003), totaling 0.008, well within budget. These sources may discuss payment channels, HTLCs, or off-chain protocols. Other skipped sources are either irrelevant (e.g., gardening, retro games) or too expensive (Latent.Space at 0.004, but not needed if cheaper ones suffice).

Synthesizing a grounded answer from 10 source(s)…

⚖️ Sources disagreed on x402 settlement latency — S1 x402 batched settlements finalize in ~180ms on Arc testnet (sub-second finality). vs S3 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time. → trusted S1 (S1 provides specific measured data (median 178ms, p95 240ms) from a testnet, while S3 is a general reading that may not account for batching or alternative consensus. S1 is more specific and recent.)
