Crypto Clash Ahead? Banks Roll Out ZKsync-Based Cari Network to Rival Stablecoins

A consortium of five major U.S. regional banks—Huntington Bancshares, First Horizon, M&T Bank, KeyCorp, and Old National Bancorp—has launched the **Cari Network**, a tokenized deposit platform built on **ZKsync**’s Prividium infrastructure. Announced on March 17, 2026, the initiative aims to provide a regulated, blockchain-based alternative to non-bank stablecoins like USDT and USDC, enabling instant, 24/7 settlement of digital representations of bank deposits.

**Cari Network** leverages Prividium, a private, permissioned Layer-2 solution from Matter Labs (ZKsync’s developer), anchored to Ethereum for security. It uses zero-knowledge technology for privacy-preserving transactions, separating sensitive data from on-chain records while ensuring auditability and compliance. Tokenized deposits remain direct liabilities of participating banks, preserving FDIC insurance eligibility and keeping funds within the regulated U.S. banking system—unlike public stablecoins issued by entities like Tether or Circle.

The banks, collectively managing hundreds of billions in assets, seek to counter stablecoin dominance in payments, remittances, and digital finance. Stablecoins have captured significant volume due to speed and global reach, but they often operate outside traditional oversight, raising concerns about deposit flight from banks. Cari offers comparable benefits—near-instant transfers, programmability, and low costs—while maintaining institutional control, KYC/AML adherence, and customer relationships.

**ZKsync’s edge** includes off-chain processing for high throughput, reduced fees versus Ethereum mainnet, and enhanced privacy/security, positioning it as attractive for regulated finance.

Potential market impact includes heightened competition in digital payments, fostering TradFi-DeFi collaboration, and pressuring crypto issuers to boost transparency. However, challenges remain: achieving broad adoption among banks and users, interoperability with existing systems, cross-border regulatory alignment, and competing against entrenched stablecoin ecosystems with deep DeFi integration.

The network is in testing phases, with an MVP piloted soon and broader production rollout targeted for later in 2026. This development highlights accelerating convergence between traditional banking and blockchain, potentially reshaping payments while preserving regulatory safeguards.
