Regional Banks Declare War on Stablecoins With ZKsync-Based

A group of five U.S. regional banks is making a direct push into digital money, launching a shared blockchain-based platform designed to offer tokenized bank deposits as an alternative to private stablecoins. The project, called the Cari Network, uses a ZKsync-based Layer 2 architecture and is aimed at bringing real-time, programmable payments into the regulated banking system. The move matters because it shows regional lenders are no longer content to watch crypto-native payment rails grow around them; they want to compete on speed, settlement, and digital asset utility while keeping deposits inside insured banks.

A coordinated response to the stablecoin challenge

The Cari Network arrives at a moment when stablecoins have become a serious competitive issue for banks. Stablecoins such as USDC and USDT have gained traction in trading, settlement, and cross-border transfers because they move quickly, operate around the clock, and integrate easily with digital asset platforms. Regional banks have increasingly faced the risk that customers, fintechs, and crypto firms could shift payment activity away from traditional deposit accounts and toward blockchain-native alternatives.

Cari’s answer is not to copy stablecoins exactly, but to offer a bank-native substitute. According to the Cari Network white paper, the platform is a permissioned digital payments system built on a dual-rail architecture that links traditional bank deposit ledgers with a blockchain transaction and settlement layer. End users receive digital tokens called “Cari” that represent deposits held in their bank accounts, and those tokens can move across the network in real time.

The initial bank group includes First Horizon, Huntington Bank, KeyBank, M&T Bank, and Old National Bank, with a pilot rollout planned for the third quarter of 2026 and broader availability expected in the following quarter. Crowdfund Insider reported the consortium announcement in early March 2026 and identified the network as a permissioned Layer 2 anchored to Ethereum through Prividium, a ZKsync-based rollup from Matter Labs.

That timeline is important. It suggests the banks are moving beyond experimentation and into implementation. For years, large financial institutions have tested tokenized deposits and blockchain settlement in controlled pilots. What makes this launch notable is that regional banks, not just Wall Street giants, are now trying to build shared infrastructure that can defend their deposit base and modernize payments at the same time.

How the ZKsync-based Cari Network works

The technical design of the Cari Network is central to its pitch. The white paper says the digital rail runs on a permissioned Layer 2 blockchain that serves as the network’s shared ledger. It also states that the network’s blockchain selection is an L2 ZK rollup, chosen in part to support security, compliance, and operational control for regulated institutions. Matter Labs, the company behind ZKsync, developed Prividium as an institutional-grade Layer 2 platform for financial institutions and governments.

In practical terms, the network is built to combine blockchain speed with bank oversight. Transactions are not open to anyone in the way public crypto networks are. Participation is initially limited to U.S.-domiciled chartered banks and regulated digital asset market participants that meet the network’s eligibility standards. The white paper says every transaction includes compliance checks, and smart contracts enforce bank-side validations so that transfers lacking required attestations or approvals cannot execute on-chain.

That structure reflects a deliberate contrast with public stablecoins. Stablecoins can circulate broadly across exchanges, wallets, and decentralized finance applications, but they also raise regulatory questions around reserves, compliance, and supervision. Cari is designed to keep those controls inside a consortium framework governed by a rulebook, a board of directors, and ongoing operator oversight. The network operator controls token supply, while a settlement bank and custodian bank support fiat settlement and key custody.

According to Gene Ludwig, the former U.S. Comptroller of the Currency and founder of Promontory Financial Group, “Innovation in digital assets should strengthen, not displace, the regulated banking system.” Ludwig, who is identified as Cari’s CEO in recent coverage, framed tokenized deposits as a way to modernize payments while keeping insured deposits at the center of economic activity.

Why regional banks are moving now

The strategic logic behind the project is straightforward. Stablecoins have shown that users value instant settlement, 24/7 availability, and interoperability with digital platforms. Banks have long offered safety, regulatory clarity, and customer trust, but traditional payment rails often remain slower, more fragmented, and less programmable than blockchain-based alternatives.

Cari’s white paper makes the competitive case explicitly. It says the network is intended to help regional and community-focused institutions avoid a choice between massive technology spending and losing customers to digitally native non-bank competitors. It argues that a shared ledger can give smaller banks enterprise-grade capabilities, including instant and programmable payments, while helping them preserve their deposit franchise.

The five participating banks are not small niche players. Federal Reserve data for June 30, 2025, show First Horizon Bank with about $81.8 billion in consolidated assets and Old National Bank with about $70.7 billion. The Cari-related coverage also cited approximate asset sizes for the broader group, underscoring that this is a meaningful regional-bank coalition rather than a symbolic pilot.

The timing also reflects lessons from the banking stress of recent years. Deposit retention has become a strategic priority for regional lenders, especially as businesses and institutional clients seek faster treasury tools and more flexible liquidity management. Tokenized deposits offer banks a way to keep those balances on their books while adding digital functionality that might otherwise be captured by fintechs or crypto firms. That does not mean stablecoins disappear, but it does mean banks are trying to reclaim ground in a market they once treated as peripheral.

What it means for customers, fintechs, and crypto markets

For customers, the main appeal is the promise of faster payments without leaving the banking system. The white paper says Cari tokens are backed by deposits held in the end user’s bank account and are meant to support real-time movement of value across the network. Because the underlying funds remain deposits at chartered banks, the model is designed to preserve the protections associated with regulated banking relationships.

That said, deposit insurance should be understood carefully. The FDIC states that the standard maximum deposit insurance amount is $250,000 per depositor, per insured bank, for each account ownership category. Any claim that tokenized deposits are “FDIC-insured” depends on the status and structure of the underlying deposit account, not on the token itself as a separate product.

For fintechs and digital asset firms, Cari could create a new bridge into regulated bank money. The white paper says qualified non-bank participants can join the network after due diligence and board approval, establish banking relationships with participating banks, and distribute Cari within digital asset ecosystems. That could make the network attractive to exchanges, custodians, and payment platforms that want on-chain settlement tied directly to bank deposits rather than to standalone stablecoin issuers.

For the crypto market, the implications are more mixed. On one hand, tokenized deposits could validate the broader idea that money movement is shifting on-chain. On the other, they could intensify competition for stablecoin issuers by offering a regulated, bank-linked alternative for some institutional use cases. According to Radi El Haj, CEO of RS2, the Cari Network is a meaningful step in payments modernization, though he also said execution will be the real test.

Regional Banks Declare War on Stablecoins With ZKsync-Based Cari Network

The phrase “Regional Banks Declare War on Stablecoins With ZKsync-Based Cari Network” is dramatic, but it captures a real strategic shift. Banks are no longer treating stablecoins as a fringe crypto product. They are treating them as a payments competitor. By launching a ZKsync-based network for tokenized deposits, regional lenders are signaling that the next battle in finance is not only about regulation, but also about who controls digital cash movement.

There are still open questions. Among them:

• Whether businesses and fintechs will adopt tokenized deposits at scale
• How interoperable Cari will become with broader digital asset markets
• Whether regulators will encourage or constrain bank-issued tokenized money
• How stablecoin issuers will respond if banks gain traction with similar functionality

The network’s own documents acknowledge that implementation remains subject to regulatory approvals and institutional participation. That caveat matters because tokenized deposits sit at the intersection of banking law, payments regulation, and digital asset policy.

Still, the direction is clear. Regional banks want a seat at the table in programmable finance. Rather than allowing stablecoins to define the future of digital dollars on their own, they are building infrastructure that keeps banks, compliance controls, and deposit relationships at the center of the system.

Conclusion

The Cari Network marks one of the clearest signs yet that U.S. regional banks are moving from observation to action in blockchain-based payments. Backed by five sizable lenders and built on a ZKsync-based Layer 2 framework, the project aims to offer tokenized deposits that combine real-time settlement with the governance and controls of the regulated banking sector. If the rollout stays on schedule through the second half of 2026, it could become an important test of whether banks can match the utility of stablecoins without giving up the advantages of insured deposits and supervisory oversight. The outcome will shape not only competition in digital payments, but also the future role of banks in an increasingly on-chain financial system.
