How fast is x402 settlement?
Settlement latency depends entirely on the underlying chain. On Base (a Coinbase-backed Ethereum L2), USDC settlement typically confirms in 1-3 seconds. On Solana, settlement is sub-second. On Utexo's Bitcoin-native execution layer (USDT settlement), the operator claims roughly 50ms finality. End-to-end an x402 round-trip - 402 response, signed payload, facilitator verification, settlement, paid response - usually completes inside 2-5 seconds on production chains. Polygon, Arbitrum, and World Chain fall in a similar range.
