Coinbase AI Payment Protocol x402 Announces Joining Linux Foundation with Support from Google, Stripe, and Others

BlockBeats News, April 2nd, according to CoinDesk's report, x402, the AI payment protocol developed by Coinbase, announced its membership in the Linux Foundation and the establishment of the initial governance body, the x402 Foundation, aimed at building an open standard infrastructure for high-frequency micro-payments for AI agents.

The initial members of the x402 Foundation include Cloudflare and Stripe, with support commitments from institutions such as Adyen, Amazon Web Services (AWS), American Express, Ant International, Base, Circle, Fiserv, Google, KakaoPay, Mastercard, Microsoft, Polygon Labs, Shopify, Solana Foundation, Visa, and others.

The x402 protocol is designed for payment scenarios where AI agents autonomously execute transactions, capable of processing high-frequency microtransactions with denominations as small as one-thousandth of a cent— a scenario that traditional credit card networks struggle to efficiently support. By joining the Linux Foundation, x402 aims to address interoperability issues and build a standardized role similar to the SSL protocol for encrypted connections between browsers and servers.
