A consortium of U.S. regional banks, including Huntington Bancshares and M&T Bank, is building the "Cari Network" on ZKsync’s Prividium infrastructure. By tokenizing deposits, these lenders aim to offer the instant settlement speeds of stablecoins while keeping capital within the regulated, FDIC-insured banking system, effectively creating a direct institutional rival to non-bank digital assets.

Why are regional banks turning to ZKsync now?

Regional banks are facing a "liquidity crunch" of relevance. As stablecoins capture billions in daily volume, traditional lenders are losing their grip on the payment rails that define modern commerce. By leveraging Matter Labs and their ZKsync-based Prividium chain, these institutions are opting for a permissioned environment that mimics the efficiency of DeFi while maintaining strict KYC/AML compliance.

Unlike Mastercard's recent acquisition of BVNK to capture stablecoin flows, the Cari Network seeks to keep the deposit on the bank’s balance sheet. This is a defensive play to ensure that when the "tokenization of everything" hits the mainstream, the liquidity remains with the banks rather than migrating to offshore-issued stablecoin protocols.

How will the Cari Network function?

The architecture is designed to bridge the gap between legacy databases and programmable money. Key participants, including First Horizon, KeyCorp, and Old National Bancorp, are testing a system where:

  • Issuance: Deposits are converted into 1:1 backed digital tokens.
  • Transfer: Tokens move across the ZKsync-based Prividium layer, enabling 24/7 settlement.
  • Redemption: Tokens are burned upon conversion back to fiat, ensuring no inflationary supply shocks.

While the industry has seen Citigroup slash price targets for crypto assets due to regulatory uncertainty, this project signals that banks aren't abandoning the tech—they are simply building their own walled garden.

What are the risks of a bank-led blockchain?

While the efficiency gains are clear, the "Source of Truth" for these assets remains the bank itself. Unlike public chains where the code is the auditor, Prividium is a private, permissioned network. This means regulators retain full oversight, which is a feature for the banks but a potential bug for privacy-focused users.

FAQ

What is the Cari Network? It is a blockchain-based platform built by a coalition of U.S. regional banks to tokenize deposits, allowing for instant, 24/7 transfers between participating institutions.

Why use ZKsync for this project? Banks are utilizing ZKsync’s "Prividium" infrastructure because it offers the scalability of layer-2 rollups while providing the privacy and compliance features necessary for regulated financial institutions.

Does this replace stablecoins? It aims to compete with them. By offering the speed of stablecoins with the safety of FDIC insurance, banks hope to retain deposit liquidity that might otherwise flow into crypto-native stablecoin issuers.

Market Signal

This move validates L2 scaling tech as the backbone for institutional finance, signaling a long-term shift away from legacy SWIFT-style settlement. Watch for increased ZKsync ecosystem activity; if these regional banks successfully scale, it could trigger a massive influx of TVL into permissioned L2s by 2026.
