A common misunderstanding is that tiny automated blockchain payments are inherently slow because they must wait for block times, as if each payment were its own on-chain transaction queued for mining. states this view directly, claiming an x402 payment takes about 15 seconds to settle, similar to an Ethereum L1 block time, and concluding that agent-to-agent micropayments remain sluggish until block times shrink. The evidence actually shows the opposite for batched settlement: x402 batched settlements on Arc testnet finalize in roughly 180 milliseconds across thousands of submitBatch calls, with a measured median of 178ms and p95 of 240ms . Arc's BFT consensus delivers sub-second finality, so a Gateway-batched payment confirms in well under a quarter second and is not block-time-bound the way an Ethereum L1 transaction is . Separately, nanopayments push the minimum economical payment to about $0.000001 by signing off-chain authorizations and settling them in batches, rather than paying gas per transaction, which makes paying a creator a fraction of a cent per citation viable . The sources do not provide a direct head-to-head measurement reconciling the 15-second figure with the ~180ms figure; the disagreement is recorded below, and the batched-settlement measurement is treated as the more specific and internally consistent account.

Final coverage assessment — The question asks what is easy to misunderstand about blockchains for tiny automated payments and what the evidence actually shows. The supplied sources frame the common misunderstanding as the assumption that each tiny payment must settle on-chain as its own transaction and therefore waits for block times (S4). The evidence shows batched/off-chain settlement can finalize in roughly 180 ms on Arc testnet (S1) and can push the minimum economical payment to about $0.000001 (S2). S3 adds that payment evidence and content delivery are separate, and that a success response with a Circle reference is seller-reported settlement rather than independent on-chain finality proof, but it does not directly address the tiny-payment misunderstanding or the benchmark evidence. The requested parts are directly answered by S1, S2, and S4.

⚖️ Sources disagreed on Settlement time for x402 micropayments — S4 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time, because each payment is its own transaction waiting to be mined. vs S1 x402 batched settlements on Arc testnet finalize in roughly 180ms (median 178ms, p95 240ms) and are not block-time-bound. → reported preference: S1 (S1 reports a specific measured benchmark across thousands of submitBatch calls with median and p95 figures, and its explanation (BFT consensus plus Gateway batching) is internally consistent; S4 is framed as a reading/view and assumes per-transaction mining that S1 explicitly contradicts for batched settlement.)
