Major payments processor Fiserv has launched INDX, a new 24/7 cash settlement platform for digital asset companies. The system allows instant US dollar transfers using a single custodial account, providing up to $25 million in FDIC insurance. This move aims to strengthen fiat infrastructure for crypto exchanges and trading desks by offering banking system settlement with blockchain-like, round-the-clock availability.
Fiserv, a major U.S. payments and financial technology provider, has launched a new cash settlement platform for digital asset companies. This move could strengthen fiat infrastructure for crypto players and improve access to liquidity.
The company announced the debut of INDX, a real-time cash settlement system that operates 24 hours a day, 365 days a year. The platform allows digital asset companies to move U.S. dollars instantly using a single custodial account.
INDX will be made available to more than 1,100 insured financial institutions participating in the Fiserv Deposit Network. The account structure provides up to $25 million in Federal Deposit Insurance Corporation coverage, according to the company.
The launch is notable because many digital asset companies still rely on traditional banking rails that operate only during business hours. By enabling round-the-clock U.S. dollar settlement within the banking system, INDX offers functionality similar to blockchain-based settlement while remaining offchain.
Fiserv generated more than $21 billion in revenue in fiscal 2025. The company has also expanded its footprint in digital assets, involved in North Dakota’s state-backed stablecoin initiative.
INDX is the latest example of an established financial institution building infrastructure for the digital asset sector. For institutional clients, the platform offers a more familiar banking framework while introducing faster, always-on cash management capabilities.
The Milwaukee, Wisconsin company in December completed the acquisition of Stone Castle Cash Management. This move was widely seen as bolstering its FIUSD stablecoin, launched in June 2025.
While INDX stands out for combining traditional bank settlement with continuous-dollar availability, other companies have also prioritized real-time settlement. For example, Sygnum operates a round-the-clock multi-asset network that enables instant settlement for institutional clients.
Similarly, Fireblocks supports real-time settlement infrastructure for stablecoins and digital asset transfers. This helps institutions streamline liquidity management.
