Stellar joins the x402 Foundation as a premier member

What x402 does

The Linux Foundation has announced the operational launch of the x402 Foundation, a new open-governance body formed to steward the x402 protocol, the open standard for internet-native payments over HTTP. @StellarOrg's Stellar Development Foundation has joined as a Premier member, placing the blockchain nonprofit alongside some of the biggest names in finance and technology.

The x402 protocol, originally contributed by Coinbase, embeds secure payment capabilities directly into web interactions so that AI agents, APIs, and applications can send and receive payments as seamlessly as they exchange data, with support for payment types ranging from traditional cards to stablecoins. The protocol is built explicitly for autonomous AI agents: machines can encounter a paywall, read the x402 response, and settle the payment via a pre-authorized wallet with no human intervention required.

Stellar's near-zero transaction fees make it a natural fit for micropayments within the standard. AI agents can discover, authorize, and settle payments programmatically within user-defined spending rules, meaning the workflow does not break where the payment begins.

A premier-tier consortium

Premier members of the x402 Foundation include Adyen, Amazon Web Services, American Express, Circle, Cloudflare, Coinbase, Fiserv, Google, Mastercard, Monad Foundation, MoonPay, Ripple, Shopify, Solana Foundation, Stellar Development Foundation, Stripe, and Visa. Since the Foundation signaled its intent to launch in April 2026, 40 organizations have joined as members in total.

Under the neutral governance of the @linuxfoundation, the x402 Foundation will allow developers, financial institutions, cloud providers, and other community members to collaboratively shape the protocol's development, ensuring that payments remain secure and adaptable across multiple payment types without vendor lock-in.

For @StellarOrg, the membership reflects a deliberate push into agentic commerce infrastructure. The Stellar Development Foundation is a nonprofit built around a mission of creating equitable access to the global financial system through blockchain technology. Joining the x402 Foundation puts that mission directly at the intersection of AI-driven payments, an area that Galaxy Research estimates could represent $3 to $5 trillion in B2C revenue by 2030.
