The Linux Foundation announced on July 14, 2026, the official launch of the x402 Foundation, a new organization managing an HTTP payment standard for AI agents. The foundation brings together 40 companies and organizations from finance, cloud, and payments, with Ripple joining as a Premier Member. Ripple plans to integrate its XRP token and RLUSD stablecoin into the standard, expanding their use cases into AI-driven micropayments.
x402 Protocol Moves to Open Governance
The x402 protocol, originally developed by Coinbase, has transitioned from a single-company project to an open-governance standard under the Linux Foundation. The protocol embeds payment functionality into HTTP communications, allowing AI agents and APIs to execute transactions without human approval. Linux Foundation CEO Jim Zemlin emphasized the need for a secure, interoperable payment infrastructure as AI agents become economic participants, and the foundation aims to foster x402 as an open standard.
Major Industry Players Join as Premier Members
The foundation is structured into three membership tiers: Premier Member, General Member, and Associate Member. Premier Members include Google, Visa, Mastercard, Stripe, AWS, and Ripple, alongside other global firms. Tom Adams, CTO of Adyen, expressed support for an open payment standard usable by both merchants and AI agents. The broad industry backing signals strong momentum for the standard's adoption.
Ripple's XRP and RLUSD Positioned for AI Micropayments
Ripple had already been developing AI agent payment solutions before joining the foundation. In June 2026, it released the XRPL AI Starter Kit, a developer toolset enabling XRP and RLUSD payments compatible with x402. The XRP Ledger (XRPL) offers predictable transaction costs, making it well-suited for the high-volume, low-value payments typical of AI agents. The foundation recognizes XRPL as one of the networks with existing implementation experience.
Expanding Real-World Asset Tokenization and Brand Reach
Beyond AI payments, XRPL has seen real-world asset (RWA) tokenization balances exceed 650 billion yen, demonstrating growing on-chain utility. Ripple has also secured a multi-year sponsorship deal to display the XRP logo on all athletic team uniforms at the University of Kansas, boosting mainstream awareness. With its participation in the x402 Foundation, Ripple is advancing XRPL's practical applications in both RWA and AI agent payments.
