Fiserv Launches INDX for 24/7 Real-Time USD Settlement for Crypto
Fiserv, a major U.S. payments and financial technology provider, has introduced INDX, a real-time U.S. dollar settlement platform for digital asset firms that operates 24/7/365. The system enables instant movement of U.S. dollars via a single custodial account, aiming to reduce banking friction and improve access to liquidity.
According to the company, INDX will be accessible 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 (FDIC) coverage.
The rollout addresses the sector’s reliance on traditional banking rails limited to business hours or onchain token transfers to move dollar value. By offering round-the-clock U.S. dollar settlement within the banking system, INDX delivers offchain capabilities comparable to blockchain-based settlement.
Fiserv is one of the largest providers of payments and financial services technology, offering core banking, merchant acquiring and transaction processing. The company reported more than $21 billion in revenue in fiscal 2025.
The firm has expanded its presence in digital assets, including participation in North Dakota’s state-backed stablecoin initiative, where it is supplying payments and settlement infrastructure to support the program’s deployment.
Traditional finance and digital assets continue to converge
INDX is the latest example of an established financial institution developing infrastructure for the digital asset market. For institutional clients, the platform provides a familiar banking framework while enabling faster, always-on cash management.
The system could also position Fiserv ahead of legacy banking partners that still rely on batch-based processing for U.S. dollar transfers. For exchanges, trading desks, stablecoin issuers and custodians, dependable, real-time dollar liquidity can offer a significant operational advantage.
In December, Fiserv completed the acquisition of Stone Castle Cash Management, a provider of bank liquidity services, in a move widely viewed as reinforcing its FIUSD stablecoin, launched in June 2025.
Beyond settlement speed, traditional financial institutions are increasingly treating stablecoins as liquidity infrastructure. Always-on digital dollars can support collateral mobility, treasury operations and cross-border payments with fewer intermediaries and reduced settlement friction.
Other firms are also emphasizing real-time settlement. Sygnum operates a continuous multi-asset network that enables instant settlement across fiat currencies, stablecoins and other digital assets for institutional clients. Fireblocks supports real-time settlement infrastructure for stablecoins and digital asset transfers to streamline liquidity management.
