The Solana Foundation has become a member of the newly formed x402 Foundation, an open-source payment network stewarded by the Linux Foundation. This initiative, announced on April 2, 2026, aims to create a standardized, internet-native payment layer by modernizing the long-unused HTTP 402 "Payment Required" status code.
The coalition behind the x402 Foundation is a who's who of global technology and finance leaders, including Visa, Stripe, Shopify, Microsoft, Mastercard, Google, Fiserv, Coinbase, Cloudflare, Circle, American Express, and Amazon. The protocol is designed to enable seamless, autonomous value transfers for AI agents, applications, and APIs directly over the web, functioning as a universal "handshake" for transactions.
Solana is positioned as a key technological backbone for this new standard. As an early adopter, the Solana blockchain has already facilitated 65% of the transfer volume on the x402 network this year, underscoring its pivotal role in advancing "agentic finance." The protocol leverages blockchain-based settlement, with a focus on stablecoins, to enable micro-transactions with near-instant finality and sub-cent costs, solving the incompatibility of traditional payment systems with machine-to-machine commerce.
"The x402 Foundation will create an open, community-governed home to develop these capabilities in the open," stated Jim Zemlin, CEO of the Linux Foundation. Rishin Sharma, Solana Foundation's Head of AI Growth, added, "We're eager to support the x402 Foundation to build the future of agentic payments and onboard more developers, merchants, and agents to pay-per-request models with stablecoins."
By placing the protocol under the vendor-neutral governance of the Linux Foundation, the partners aim to ensure interoperability, transparency, and prevent proprietary control. This collaboration marks a significant step toward decoupling digital commerce from fragmented credit card networks and establishing a unified financial layer for the digital age.
