How Fiserv's INDX Platform Is Reshaping Dollar Access for Crypto Companies

Crypto companies operating globally face a fundamental challenge: liquidity constraints. Traditional financial infrastructure wasn’t designed for the always-on economy that digital asset firms now demand. Most crypto companies still wrestle with limitations imposed by conventional banking hours, expensive correspondent banking networks, and the friction of managing multiple banking relationships. Recognizing this gap, Fiserv—a major US payments and financial services provider—has just unveiled a solution that could fundamentally alter how these firms manage dollar liquidity.

The Liquidity Challenge for Crypto Companies and Traditional Finance

For years, crypto companies have operated at a disadvantage when it comes to fiat settlement. Exchanges, trading desks, custodians, and stablecoin issuers typically depend on legacy banking systems that process transactions only during business hours, creating operational bottlenecks. When crypto companies need to move significant dollar amounts, they often face delays, fragmented banking relationships, or resort to inefficient onchain token transfers. This patchwork approach to liquidity management has long been a drag on institutional adoption and operational efficiency in the digital asset space.

The broader challenge extends beyond speed. Crypto companies seeking institutional-grade banking relationships must often navigate multiple custodial accounts across different institutions, each with its own compliance requirements and fee structures. This fragmentation has historically created friction for digital asset platforms looking to scale operations while maintaining robust treasury and collateral management systems.

Fiserv’s 24/7 Settlement Rails: What Sets INDX Apart

Enter INDX, Fiserv’s newly launched real-time cash settlement system that operates continuously—24 hours a day, 365 days a year. The platform allows crypto companies to instantly move US dollars through a single custodial account, streamlining their fiat management workflows. This represents a meaningful shift toward infrastructure designed specifically for the needs of digital asset firms.

INDX gains additional credibility through its insurance framework. The account structure provides up to $25 million in Federal Deposit Insurance Corporation (FDIC) coverage, a safety net that matters significantly for institutional crypto companies managing large dollar balances. The platform becomes available to more than 1,100 insured financial institutions participating in the Fiserv Deposit Network, creating a broad foundation for adoption across the ecosystem.

What makes INDX particularly significant is its hybrid approach: it preserves the regulatory familiarity of traditional banking while introducing the speed and availability that crypto companies desperately need. By enabling round-the-clock US dollar settlement within the established banking system, INDX delivers blockchain-like settlement velocity without requiring firms to migrate entirely to decentralized alternatives.

Fiserv’s broader expansion into digital assets underscores its strategic commitment. The company generated over $21 billion in revenue during fiscal 2025 and has already built meaningful relationships within the crypto ecosystem. In December, Fiserv completed its acquisition of Stone Castle Cash Management, a move widely interpreted as strengthening its FIUSD stablecoin initiative launched in June 2025. This acquisition signals that Fiserv views reliable dollar infrastructure as central to its long-term digital asset strategy.

TradFi’s Convergence With Digital Assets: Market Implications

INDX exemplifies the broader trend of established financial institutions building purpose-built infrastructure for crypto companies and digital asset ecosystems. For traditional finance players, this represents an opportunity to capture wallet share among fast-growing digital asset firms seeking regulatory compliance and operational reliability. For crypto companies, partnerships with established financial institutions offer access to familiar banking frameworks combined with next-generation liquidity capabilities.

The importance of always-on digital dollar infrastructure extends beyond settlement speed. Traditional financial institutions increasingly view stablecoins and continuous-dollar systems as essential liquidity infrastructure. Round-the-clock access to digital dollars can facilitate collateral movement, treasury operations, and cross-border payments with fewer intermediaries and substantially reduced settlement friction—advantages that benefit both crypto companies and their institutional counterparts.

Other market participants have similarly prioritized real-time settlement infrastructure. Sygnum operates a round-the-clock multi-asset network enabling instant settlement across fiat currencies, stablecoins, and other digital assets for institutional clients. Fireblocks has built complementary infrastructure supporting real-time stablecoin settlement and digital asset transfers, helping institutions streamline their liquidity management. However, INDX stands out by combining traditional banking settlement guarantees with the continuous-dollar availability that crypto companies specifically require.

The convergence between TradFi and digital assets continues accelerating. As platforms like INDX demonstrate, the future may not require crypto companies to choose between regulatory certainty and operational efficiency—they can increasingly access both simultaneously through partnerships with established financial infrastructure providers.
