🚨Secure Bank Transfers, Just ZK It.
> ZKsync just made bank money move at light speed.
Do you know banks still run on systems built decades ago? Massive amounts of deposits sit in place, but moving funds between institutions or across different systems often slows down because of outdated settlement cycles, multiple intermediaries taking their share, and capital that stays locked up simply to manage risks. These inefficiencies operate at a scale that becomes clear only when looking closely at correspondent banking and the constant liquidity drag in traditional finance.
This is exactly where ZKsync’s work on the ZKsync Network (consist of more than 15 ZKchain) and native ZK Interop makes a meaningful difference. The foundation goes back to the zkLite days in 2020, and today it delivers native, trustless transfers that settle in roughly one second across public and private ZK chains, all with the full security and finality that Ethereum provides. No external bridges that introduce new risks, and no fragmentation that breaks composability.
The privacy and compliance approach stands out even more clearly through Prividium. Banks and institutions can keep sensitive details, exact balances, counterparties, and internal workflows, completely shielded from public view, while still generating ZK proofs that verify everything on Ethereum. This directly addresses the long standing challenge of balancing real confidentiality for financial data with the need for verifiable, auditable settlement.
The results are already visible with the Cari Network, developed in partnership with five major U.S. regional banks: Huntington, First Horizon, M&T Bank, KeyBank, and Old National. These institutions represent substantial scale, with hundreds of billions in deposits and trillions in assets across the broader group. They are issuing tokenized deposits that remain direct liabilities on the banks’ balance sheets, FDIC-insured, fully regulated, programmable, and capable of moving 24/7 in real time. This upgrades the flow of money within the existing banking system instead of pulling away from it.
For those tracking tokenized real-world assets (in short, RWA’s) and institutional onchain adoption, this represents one of the more practical and grounded developments in the space. It really, genuinely, tackles the actual frictions that have kept traditional finance on the sidelines, while, at the same time, delivering the speed, interoperability, and control that institutions require, without forcing difficult trade-offss.
From the early zkLite through to today’s full ZKsync Network capabilities, ZKsync team has shown a rare consistency. As traditional banking and onchain systems gradually converge, developments like this stand out, because they address the real frictions that have kept meaningful adoption at bay for years. And patient progress is exactly what the space needs if tokenized finance and institutional-grade infrastructure are going to scale sustainably.
So.
Just ZK It.
