Coinbase-Initiated x402 Foundation Sets Out to Build a Universal Open Payment Standard for the Web

TLDR:

• Coinbase initiated the x402 Foundation under the Linux Foundation alongside Cloudflare and Stripe as co-founders.
• Over 20 founding members joined, including Google, Microsoft, Visa, Mastercard, AWS, Circle, and Shopify.
• The x402 protocol supports both fiat and crypto rails across multiple blockchains and payment networks globally.
• AI agents can now make automated payments without manual authorization using the open x402 payment standard.

x402 Foundation has officially launched as a non-profit organization under the Linux Foundation. Coinbase initiated the effort alongside Cloudflare, Stripe, and a broad group of industry leaders.

The foundation aims to establish the x402 protocol as a universal open payment standard for the internet. Over 20 founding members have joined, including Google, AWS, Microsoft, Visa, Mastercard, Circle, and Shopify. Their collective goal is to make sending value online as seamless as sending an email.

An Open Standard Built for the Modern Internet

The internet runs on open protocols, with HTTP handling data and SMTP managing email communication. However, payments have long remained fragmented and proprietary across the web.

The x402 protocol changes this by embedding payments directly into web-based interactions. AI agents, apps, and APIs can therefore send and receive value as easily as they exchange data.

AI agents are increasingly taking on tasks for users without constant human oversight. These agents need a reliable way to pay for services without manual authorization every single time.

The x402 protocol enables fully automated payment flows across different platforms and services. This removes a key barrier for developers building tools that depend on machine-to-machine transactions.

The protocol also supports both fiat and crypto payment rails globally. It operates across multiple blockchains and payment networks without relying on a single party.

Developers can build on x402 freely without being locked into any specific financial system. This open design ensures no single company controls the direction of the standard.

In a post on X, Coinbase stated that the foundation gives x402 a neutral, community-governed home. The Linux Foundation hosts the initiative to keep it free from commercial influence.

No single company owns the x402 standard under this structure. This governance model keeps the protocol open and accessible to participants of all sizes.

Founding Members Drive the x402 Foundation Forward

The x402 Foundation launched with over 20 founding members across technology, payments, and finance. These include Adyen, Amazon Web Services, American Express, Ant International, and Base.

Google, Microsoft, Mastercard, Visa, Circle, Stripe, Cloudflare, and Shopify are also founding members. KakaoPay, Polygon Labs, Solana Foundation, Fiserv Merchant Solutions, and Thirdweb complete the founding group.

The foundation welcomes developers, startups, and enterprises of all sizes to join its membership. Members can directly help shape how the x402 standard evolves across platforms and markets.

This inclusive model allows smaller companies to contribute alongside major industry players. Cross-border payments can become more consistent as more stakeholders adopt and build on x402.

Membership offers a direct role in governing how the world transacts online. Participants can advance the open payments standard across different regions and platforms.

The foundation mirrors how other internet protocols were built through open, collective governance. Through this shared effort, x402 can grow to serve a rapidly evolving digital economy.
