Ripple joined the x402 Foundation as a Premier Member on July 14, 2026, alongside 40 organizations developing open payment standards for AI-driven internet transactions. The company's membership gives it a role in the protocol's technical and governance development, connecting the XRP Ledger's x402 support to a broader industry effort focused on AI-driven payment infrastructure. The foundation operates under the Linux Foundation to support an open, vendor-neutral standard for payments over HTTP, with Coinbase having contributed the x402 protocol to enable payment capabilities within HTTP interactions between AI agents, APIs, and applications.
Ripple Joins x402 Foundation as Premier Member on July 14, 2026
Ripple announced on July 14, 2026, that it joined the x402 Foundation as a Premier Member. The foundation operates under the Linux Foundation and was created to support an open, vendor-neutral standard for payments over HTTP. Ripple's membership connects the XRP Ledger's x402 support to a broader industry effort focused on AI-driven payment infrastructure.
The x402 Foundation launched with 40 members across finance, cloud infrastructure, payments, and blockchain sectors. Premier Members include Adyen, Amazon Web Services (AWS), American Express, Circle, Cloudflare, Coinbase, Fiserv, Google, Mastercard, Monad Foundation, Moonpay, Ripple, Shopify, Solana Foundation, Stellar Development Foundation, Stripe, and Visa.
General members include Aleo, Fireblocks, Galaxia Moneytree, Hecto Financial, Injective, Kakaopay, Kite AI, Layerzero Labs, Merit Systems, NEAR Foundation, Orthogonal, Polygon Labs, Quant Network, SKALE, t54 labs, Utexo, World Liberty Financial, and zerohash. Associate Members include BSV Association, Cardano Foundation, Casper, Japanese Contents Blockchain Initiative, and OMA3. The group operates under open governance to develop an interoperable payment standard.
Coinbase Contributed x402 Protocol to Linux Foundation for AI Payment Standard
The x402 protocol was contributed by Coinbase to the Linux Foundation as an open standard for internet-native payments. The protocol allows AI agents, APIs, and applications to send and receive payments directly through web interactions, letting software exchange value alongside data. The protocol supports multiple payment methods, including traditional cards, stablecoins, and blockchain-based assets.
The standard was designed to address a limitation exposed by AI agents. Software can already exchange information and access services, but internet infrastructure lacks a standard way for one program to pay another. X402 aims to provide a native payment layer for AI-driven commerce while supporting different payment methods.
Linux Foundation CEO Jim Zemlin said the launch represented progress toward a community-governed payment standard. "The operational launch of the x402 Foundation marks a vital milestone in establishing an open, community-governed standard for payments over HTTP. By bringing together leading companies across finance, technology, and more, we're ensuring that the payment layer of the internet remains neutral, highly interoperable, and ready to support digital commerce."
XRP and RLUSD Support x402 Transactions Through XRP Ledger Infrastructure
Ripple's participation highlights the XRP Ledger's compatibility with x402. The company has highlighted XRP Ledger infrastructure supporting agentic payments through x402, including transactions using XRP and Ripple USD (RLUSD) stablecoin.
Markus Infanger, senior vice president of RippleX, described Ripple's role in supporting that development. "We've been building the tools and infrastructure needed to support that future on the XRP Ledger, including support for x402 that enables agents to transact using XRP and RLUSD today."
Ripple's membership gives the company a role in developing standards for machine-to-machine payments, while XRP and RLUSD already have support within the x402 framework. However, x402 supports multiple payment methods, meaning XRP will operate alongside traditional payment systems, stablecoins, and other blockchain networks as adoption develops.
