Linux Foundation is Launching the x402 Foundation and Welcoming the Contribution of the x402 Protocol

New Foundation will steward the open x402 protocol for seamless payments over HTTP

NEW YORK – MCP Dev Summit North America – April 2, 2026 – The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced it is launching the x402 Foundation with the contribution of the x402 protocol from Coinbase. The new Foundation will serve as the neutral home for x402, a universal standard for payments that embeds payments directly into web interactions, enabling AI agents, APIs, and apps to transact value as seamlessly as they exchange data.

The x402 protocol, created by Coinbase, is moving to the Linux Foundation. The x402 Foundation, the standard’s governing body, initially developed by Coinbase, Cloudflare, and Stripe, is launching with a broad set of industry participants as it migrates toward an open source model for the benefit of all internet-native payments.

Membership will be comprised of participants from multiple verticals with initial intent and support being expressed by Adyen, Amazon Web Services, American Express, Ampersend.ai, Base, Circle, Cloudflare, Coinbase, Fiserv Merchant Solutions, Google, KakaoPay, Mastercard, Merit Systems, Microsoft, Polygon Labs, PPRO, Shopify, Sierra, Solana Foundation, Stripe, thirdweb, and Visa.

"The internet was built on open protocols," said Jim Zemlin, CEO of the Linux Foundation. "The x402 Foundation will create an open, community-governed home to develop these capabilities in the open, ensuring they evolve with transparency, interoperability, and broad participation across the ecosystem."

Under Linux Foundation governance, the x402 protocol will remain vendor neutral, fostering transparent, community-driven growth, ensuring accessibility, and supporting sustainability.
