x402 is already showing 75.4M transactions and $24.2M volume over the last 30 days; the hard part now is deciding which autonomous payments should exist before money moves. GrailPay’s useful claim is 99% U.S. bank-account coverage plus per-payment scoring and indemnification across ACH and instant rails, because FedNow/RTP and stablecoins both compress the fraud window to near-zero. If that risk layer becomes portable, agentic commerce gets an offchain trust graph instead of another per-app KYC silo.
