The Linux Foundation announced the launch of the x402 Foundation on April 2, 2026, during the MCP Dev Summit North America in New York. The initiative involves the formal contribution of the x402 protocol from Coinbase to the Linux Foundation to serve as a neutral, open-source standard for internet-native payments. This protocol enables artificial intelligence (AI) agents, application programming interfaces, and apps to transact value directly within web interactions.
The transition to an open-source model aims to ensure transparency and interoperability across the global financial ecosystem. The foundation launches with support from over 20 industry leaders, including Google, Microsoft, and Visa. Current data indicates the Solana Foundation has been an early adopter, accounting for nearly 65% of x402 transaction volume this year.
“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,” said Jim Zemlin, CEO of the Linux Foundation.
