Ripple has joined the Linux Foundation's new x402 Foundation as a premier member, bringing XRP and its RLUSD stablecoin into an open-source initiative to standardize internet-native payments for AI agents. The foundation, announced with 40 member organizations including Amazon Web Services, American Express, Circle, Coinbase, Google, Mastercard, Shopify, Solana Foundation, Stellar Development Foundation, Stripe, and Visa, will oversee the x402 protocol—an open payment standard that lets AI agents, APIs, and applications send and receive payments directly over HTTP. The goal is to make financial transactions as seamless as data exchange on the internet.
XRP Ledger's Role in Machine-to-Machine Payments
Ripple has already integrated x402 support on the XRP Ledger, enabling AI agents to transact using XRP and RLUSD. The company argues that the ledger is well-suited for autonomous AI transactions due to its deterministic settlement and predictable transaction costs. Jazzi Cooper, RippleX's senior developer relations engineer, noted that most discussions about AI agents focus on capabilities rather than the infrastructure needed for them to pay for services autonomously. "The harder problem is how they pay for it," she said.
Cooper highlighted that the XRP Ledger addresses key technical challenges for machine-to-machine payments, including 3-5 second deterministic finality, no gas auctions, and no ambiguous pending states. "An agent doesn't need retry logic or polling loops, it just proceeds the moment a transaction confirms," she explained, adding that this is the difference between infrastructure built for human approvals and infrastructure built for machines making decisions in milliseconds.
Practical Applications and Future Development
Last month, Ripple released its XRPL AI Starter Kit, and with x402 support now live, Cooper said those tools can already be used in production scenarios. Ripple has committed to contributing to the foundation's governance and technical development, signaling a push to embed XRP and RLUSD into the emerging ecosystem of AI-driven commerce. The x402 Foundation's broad industry backing suggests a concerted effort to create a standard for autonomous payments, potentially reshaping how AI agents, APIs, and applications interact financially on the internet.
