Fiserv, a major player in payments and financial services technology (NASDAQ: FISV), officially launched INDX on February 12, 2026. This is a real-time cash settlement platform specifically built for digital asset companies (such as crypto exchanges, institutional traders, and other firms in the space). The platform allows these companies to securely store and transfer US dollars in real time, operating 24/7/365, without needing to move funds on-chain or route them through non-traditional banking channels.
Let us explain.
There are several key features of INDX, which include: A single custodial account that is provided through an affiliated US-based trust company, offering institutional-grade security and accessibility; Instant, final settlements where transfers happen in milliseconds, with funds immediately available in pure USD; Enhanced FDIC insurance, with balances distributed across the Fiserv Deposit Network (which includes over 1,100 insured US-based financial institutions, like community banks and credit unions) qualify for up to $25 million in FDIC coverage, described as 100x more than a standard single account; Programmability, using real-time API access for custom controls, integrations, and automation and last but not least, off-chain security with on-demand speed, funds stay in the traditional banking system (keeping them “off-chain” for safety) while delivering the fast, flexible operations that digital asset firms need.
Where did this new program come from?
This launch builds directly on Fiserv’s acquisition of StoneCastle Cash Management, which closed in December 2025. StoneCastle brought expertise in insured deposit networks and liquidity solutions, and INDX combines that with Fiserv’s broader ecosystem to create a bridge between traditional banking rails and digital asset needs. For the banks and credit unions in the Fiserv network, INDX creates a new source of stable, low-cost, granular deposits from digital asset flows. This appears to address common pain points in crypto/fiat operations: slow settlements, limited insurance on large balances, and reliance on riskier or slower alternatives. It’s positioned as a safer, scalable way to handle fiat while meeting the speed demands of the digital asset world.
What about Fiserv’s Circle initiatives?
Last July we wrote a deep dive on Fiserv’s new partnership with Circle Internet Group (NYSE: CRCL), as a brief refresher: “The collaboration is designed to facilitate real-time, cost-effective, and cross-border payment capabilities for banks, FinTech firms, and merchants. Payment activities within this framework broadly fall into two categories: business-to-business (B2B) and consumer-to-business (C2B), such as point-of-sale transactions.” In essence, when combined with INDX, this creates a hybrid setup: INDX handles the fiat “leg” with banking-grade safety and speed, while Circle integrations handle the stablecoin “leg” for on-chain or cross-border use cases.
Why should FinTech observers care about Fiserv and the above mentioned announcements?
Because it matters. The Fiserv ecosystem encompasses 10,000 financial institutions and six million merchant locations, collectively processing 90 billion transactions each year. Currently, a significant portion of clients and transactions rely on legacy architectures, such as traditional payment systems, which contribute to higher service costs. As fintech continues to evolve into a new phase of digital transformation, Fiserv is well-positioned to lead the transition toward continuous availability, reduced costs, accelerated transaction speeds, and enhanced access to information.
Something tells us we will be writing on this topic again, and as always, for those who are interested in knowing more please reference Fiserv’s SEC filings, web site, earnings conference call transcripts and press releases.
