Ripple has joined the Linux Foundation’s newly launched x402 Foundation as a premier member.
It is bringing XRP and its RLUSD stablecoin into an open-source initiative that is meant 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 said it has already integrated support for x402 on the XRP Ledger, allowing AI agents to transact using both XRP and RLUSD.
Ripple added that it is looking forward to contributing 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, Ripple, Shopify, Solana Foundation, Stellar Development Foundation, Stripe and Visa.
AI payments
Ripple argues that the XRP Ledger is particularly well suited for autonomous AI transactions because of its deterministic settlement and predictable transaction costs.
Jazzi Cooper, RippleX’s senior developer relations engineer, said much of the discussion around AI agents has focused on their capabilities rather than the infrastructure needed to let them pay for services autonomously.
“Most of the agentic payments conversation is still about what agents can do. The harder problem is how they pay for it.”
According to Cooper, the XRP Ledger already addresses many of the technical challenges associated with machine-to-machine payments. “On XRPL, that’s already solved: 3-5 second deterministic finality, no gas auctions, no ambiguous pending states.”
She added that this eliminates much of the complexity developers face when building autonomous systems. “An agent doesn’t need retry logic or polling loops, it just proceeds the moment a transaction confirms.” “That’s the difference between infrastructure built for humans clicking ‘approve’ and infrastructure built for machines making decisions in milliseconds,” she added.
Last month, Ripple released its XRPL AI Starter Kit. With x402 support now live, Cooper said those tools can already be used in production scenarios.
