Nacha and J.P. Morgan Launch Integrated Network to Fortify Global Payments

RESTON, VA – February 05, 2026 – In a significant move to bolster the security and efficiency of the financial system, Nacha and J.P. Morgan have announced that the integration between their respective payment information networks, Phixius and Kinexys Liink, is now live. The collaboration creates a powerful, multi-layered system for validating bank account information in near real-time, aiming to drastically reduce payment fraud and costly errors for trillions of dollars in transactions.

This partnership connects Phixius by Nacha, a secure data exchange network, with Kinexys Liink, J.P. Morgan's enterprise-grade blockchain platform. The result is a unique “multi-responder” account validation network. Financial institutions and corporations making payments can now verify the accuracy of recipient bank account data by querying multiple trusted sources through a single connection, increasing confidence and coverage across the U.S. payment landscape and beyond.

A New Defense Against Payment Fraud and Errors

The need for more robust validation tools has never been more critical. The ACH Network, governed by Nacha, is a cornerstone of the U.S. economy, processing an astonishing 35.2 billion payments valued at $93 trillion in 2025 alone. While overwhelmingly reliable, the sheer volume of transactions creates opportunities for fraud and simple human error, which can lead to misdirected payments, costly returns, and operational bottlenecks. These issues are magnified in cross-border transactions, where varying data standards and a lack of interoperability create friction and risk.

This new integrated network directly confronts these challenges. By enabling near real-time validation before a payment is initiated, the system helps prevent errors at the source. For businesses and financial institutions, this translates into tangible benefits: fewer returned payments and associated fees, reduced risk of sending funds to fraudulent accounts, and a significant decrease in the manual labor required to investigate and resolve payment exceptions. The enhanced security is a crucial development in an era of increasingly sophisticated payment fraud schemes.

“Phixius’ live integration with Kinexys Liink provides a unique multi-responder model that delivers clear value to data requesters,” said Rob Unger, Managing Director of ACH Network Development at Nacha, in the original announcement. “This integration reflects a shared commitment to providing clients with secure, efficient solutions that address the growing need for accurate account validation.”

The Technology Behind the Alliance: Blockchain Meets API

At the heart of this collaboration is the synergy between two distinct but complementary technologies. Phixius, launched by Nacha in 2020, operates as a secure, API-driven gateway. It does not store account data in a central repository; instead, it acts as a secure switchboard, routing validation requests to a federated network of trusted data responders. This decentralized approach enhances security and privacy, a design validated by its SOC 2 Type 2 certification.

Kinexys Liink, part of J.P. Morgan’s Kinexys blockchain unit, provides the global, blockchain-based infrastructure. Originally launched as the Interbank Information Network, Kinexys Liink is designed for secure, peer-to-peer information exchange between financial institutions. Its “Confirm” application allows for the validation of billions of bank accounts worldwide. The blockchain technology provides an immutable and auditable record of information exchange, ensuring data integrity and trust among network participants without centralizing sensitive information.

Together, they create a powerful, two-way street for data validation. Kinexys Liink users can now tap into the rich network of U.S. data responders on Phixius. Conversely, Phixius participants gain access to Kinexys Liink’s extensive global reach, providing a much-needed bridge for validating international account information.

Forging a Strategic Partnership for a Global Network

The alliance between Nacha, the steward of the U.S. ACH Network, and J.P. Morgan, a global financial titan and blockchain pioneer, marks a pivotal moment for the payments industry. It demonstrates a pragmatic and powerful application of blockchain technology to solve real-world problems within the traditional financial framework. Rather than seeking to replace existing payment rails, this integration enhances them, making them safer and more efficient.

The collaboration is a textbook example of the “network effect.” As more financial institutions and data providers join either Phixius or Kinexys Liink, the value for all participants increases exponentially. The depth and breadth of verifiable data grow, making the system more robust and comprehensive. This creates a virtuous cycle that strengthens the entire payment ecosystem against fraud and operational risk.

“We are excited to bring this collaboration to life,” commented Gloria Wan, General Manager, Kinexys Liink at Kinexys by J.P. Morgan. “By connecting to the Phixius network, we are enabling the global distribution of U.S. account validation data, strengthening the security of cross-border payments and amplifying the benefits of network effect across the ecosystem.”

This partnership sets a precedent for how established payment system operators and innovative fintech units within large banks can collaborate to drive industry-wide improvements. It moves beyond theoretical discussions of blockchain's potential and delivers a live, scalable solution with immediate benefits. For the financial institutions and corporations that move trillions of dollars daily, this new level of assurance in the accuracy of payment data is a welcome and critical advancement.
