⚖️ Sources disagreed on x402 payment settlement time — S1 x402 batched settlements finalize in roughly 180 milliseconds on Arc testnet. vs S3 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time. → trusted S1 (S1 provides specific, measured benchmarks from a testnet (Arc) with median and p95 values, while S3 offers a general claim without supporting data. S1 is more precise and internally consistent.)

x402's protocol reduces latency compared to traditional nanopayment gas models through several mechanisms. First, it eliminates on-chain transactions for each individual payment by using cryptographic commitments that are settled off-chain or batched. This avoids per-payment gas fees and block confirmation times . Second, x402's optimistic verification mechanism allows payments to be authorized off-chain and settled in batches, with batched settlements on Arc testnet finalizing in roughly 180 milliseconds (median 178ms, p95 240ms) — far faster than Ethereum L1 block times . In contrast, traditional nanopayment gas models require each payment to be its own on-chain transaction, leading to settlement times of about 15 seconds, similar to an Ethereum L1 block time . Additionally, x402 leverages HTTP/2 or similar transport-layer multiplexing to interleave payment proofs with data streams, reducing round-trip overhead compared to separate payment channels .
