CoinDesk·medium signal

CoinDesk (July 16, 2026) details the Linux Foundation-affiliated x402 Foundation, now 40 members, building an open HTTP-native payment standard for AI agents named after the '402 Payment Required' status code. Premier members span payments (Visa, Mastercard, Amex, Stripe, Adyen, Fiserv), tech (Google, AWS, Cloudflare, Shopify), and crypto (Coinbase, Ripple, Circle, Solana Foundation); Alin Dragos (AWS Payments) chairs the board while an executive director is recruited. The goal is machine-to-machine 'agentic commerce' and micropayments without subscriptions or manual card entry.
