Ripple has joined the newly launched x402 Foundation, an initiative backed by the Linux Foundation, as a premier member. This move brings XRP and Ripple's RLUSD stablecoin into an open-source project designed to standardize internet-native payments for AI agents and applications.
The x402 Foundation will oversee the development of the x402 protocol, an open payment standard that enables AI agents, APIs, and applications to send and receive payments directly over HTTP. The protocol aims to make financial transactions as seamless as exchanging data on the internet.
Ripple has already integrated support for x402 on the XRP Ledger, allowing AI agents to transact using both XRP and RLUSD. The company also plans to contribute to the foundation's governance and technical development.
The foundation launches with backing from 40 organizations, including Amazon Web Services, American Express, Circle, Coinbase, Google, Mastercard, Shopify, Solana Foundation, Stellar Development Foundation, Stripe, and Visa.
According to Jazzi Cooper, RippleX's senior developer relations engineer, the XRP Ledger is well-suited for autonomous AI transactions due to its deterministic settlement and predictable costs. She noted that the ledger already solves many machine-to-machine payment challenges: transactions achieve finality in 3–5 seconds with no gas auctions or ambiguous pending states, eliminating the need for retry logic or polling loops. "That's the difference between infrastructure built for humans clicking 'approve' and infrastructure built for machines making decisions in milliseconds," Cooper said. Ripple released its XRPL AI Starter Kit last month, and with x402 support now live, those tools are ready for production scenarios.
