Fiserv Named a Charter Member of the x402 Foundation

New foundation to serve as home for open x402 protocol for internet-native payments

MILWAUKEE - May 1, 2026 - Fiserv, Inc. (NASDAQ: FISV), a leading global provider of payments and financial services technology, today announced it is a charter member of the x402 Foundation, the new neutral home for x402 protocol. Created by Coinbase, the x402 protocol is migrating to the Linux Foundation which will serve as its host.

The x402 protocol, a universal standard for internet-native payments, enables faster checkout for API-driven commerce, lower friction for new sales channels, i.e, apps, and AI agents to process and easier global expansion through interoperable rails. Created for automated, machine-to-machine (M2M) transactions, the x402 protocol is scalable across internet payment networks and encompasses stablecoins, cards, and PSPs.

The x402 Foundation will serve as the governing body for the standard and ensure a neutral, industry-led governance ecosystem. The group's mission is to support research, development, and form industry consensus on standards that will shape its use. This includes actively developing an ecosystem that ensures the agentic web is open to all through events, education, and development grants.

"Fiserv processes payments for millions of merchants - from the cornerstore to global enterprises. x402 gives us an open, interoperable foundation to ensure that, as commerce becomes more automated and agent-driven, every one of those merchants can participate," said Sanjay Saraf, Chief Product Officer of Fiserv Merchant Solutions. "We're supporting the x402 Foundation because the payment layer of the agentic web should work for businesses of all sizes, without needing massive re-engineering of their commerce capabilities."

As the protocol migrates toward an open-source model, it will continue to enable easier access to data, more widespread adoption of the protocol, transaction transparency, sustainability, and growth, resulting in benefits for the entire merchant payment ecosystem.
