Cari Network, a pioneering permissioned network for financial institutions spearheaded by former United States Comptroller of the Currency Gene Ludwig, has selected Matter Labs’ Prividium infrastructure to power its innovative bank-governed tokenized deposit network. This strategic alliance aims to equip U.S. regional and mid-sized lenders with the technology to issue and manage tokenized deposits, a significant step towards modernizing their payment and deposit functionalities. The platform, built upon the robust ZKsync technology and anchored to the Ethereum blockchain, is designed to facilitate round-the-clock movement of tokenized deposits while crucially maintaining their classification as bank liabilities on participating institutions’ balance sheets.
This development arrives at a pivotal moment for the financial industry, as legislative bodies actively engage in shaping the future of digital assets and payments. Discussions surrounding frameworks like the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act underscore the growing urgency to establish clear regulatory pathways for stablecoins and other tokenized forms of value. Simultaneously, the increasing prominence of stablecoin issuers in the payments landscape and their encroachment on traditional banking roles in deposit funding have amplified the need for incumbent institutions to adapt and innovate.
Alex Gluchowski, CEO of ZKsync, articulated the network’s core objective in an interview with Cointelegraph: "Financial infrastructure is being redesigned in real time, and mid-sized banks are the ones being left behind. This network is designed to empower them to lead that transition, rather than be displaced by it." This sentiment highlights the network’s ambition to serve as a bulwark for traditional banks, enabling them to harness the efficiencies and innovations of digital asset technology without compromising their core functions or client trust.
Regional Banks Embrace Tokenized Deposits Amidst Evolving Payment Landscape
The initiative has garnered significant traction among prominent U.S. banks. Since February, five institutions – Huntington Bancshares, First Horizon, M&T Bank, KeyCorp, and Old National Bancorp – have been actively involved in the design and testing phases of the Cari Network. This collaborative approach underscores a shared commitment to exploring and implementing next-generation financial infrastructure. The involvement of these established players suggests a growing recognition within the industry of the potential for tokenized deposits to enhance operational efficiency and customer offerings.
The broader implications of this endeavor are further supported by the Mid-Size Bank Coalition of America, which has lent its backing to the underlying model. The coalition emphasizes the critical role that keeping deposits within regulated financial institutions plays in supporting small business lending and fostering vibrant local economies. This perspective underscores the network’s alignment with the broader economic objectives of regional banking, positioning it not just as a technological advancement but as a tool for economic stability and growth.
Cari’s tokenized deposits are designed to represent existing customer deposits held at participating banks. A key architectural feature is their confinement within a permissioned environment, strictly governed by the risk and compliance frameworks already in place at these institutions. This stands in contrast to the open, permissionless nature of decentralized finance (DeFi), ensuring that these tokens remain under the purview of traditional banking regulations and oversight. This approach aims to bridge the gap between the security and trust of traditional banking and the efficiency and innovation of blockchain technology.
Prividium: A Foundation for Privacy, Control, and On-Chain Auditability
Matter Labs’ Prividium infrastructure serves as the foundational shared ledger for the Cari Network. Its design prioritizes instant settlement between verified counterparties, a critical feature for facilitating efficient financial transactions. A core tenet of Prividium is its ability to meticulously separate transaction records and balances from personally identifiable information (PII). This sensitive data remains securely within each bank’s existing core systems, adhering to stringent data privacy regulations and enhancing client confidentiality.
The underlying ZKsync technology, while having experienced fluctuations in public network usage, particularly a significant decline in transaction volume in 2025 following a cooling of airdrop-driven activity, has been strategically evolving its roadmap towards institutional adoption. Nansen’s on-chain data analysis, which indicated a notable decrease in ZKsync transactions, also highlights the platform’s pivot. ZKsync’s 2026 roadmap explicitly emphasizes privacy, deterministic control, and native interoperability as essential prerequisites for engagement with banks, enterprises, and governments. This strategic shift aligns perfectly with the requirements of the Cari Network and the broader institutional finance sector.
Gluchowski further elaborated on the architectural considerations, stating that the design was meticulously crafted with U.S. banking privacy regulations and supervisory expectations firmly in mind. This includes robust provisions for data protection, ensuring seamless examiner access for regulatory oversight, and the implementation of tamper-evident audit trails. These features are paramount for building trust and ensuring compliance within the highly regulated banking sector.
While some financial institutions have explored issuing or partnering on stablecoins, Gluchowski draws a clear distinction, arguing that tokenized deposits are “complementary to stablecoins.” He posits that tokenized deposits are ideally suited to function as the primary payment tokens utilized by banks when money needs to be transferred in and out of their private infrastructure. This perspective positions tokenized deposits not as a replacement for stablecoins, but as a distinct and complementary tool that leverages the core strengths of the banking system.
Implications for the Future of Banking and Payments
The launch of the Cari Network and its adoption of Prividium infrastructure carries significant implications for the future of the U.S. banking sector. It represents a tangible response by mid-sized and regional banks to the rapidly evolving digital asset landscape. By embracing tokenized deposits, these institutions can offer enhanced payment services that mirror the speed and efficiency of stablecoin transactions, thereby retaining and attracting customers who increasingly expect digital-first financial solutions.
The emphasis on a permissioned network governed by existing bank risk and compliance frameworks is a crucial differentiator. It allows banks to leverage blockchain technology without immediately exposing themselves to the regulatory uncertainties and operational complexities of fully decentralized systems. This measured approach to innovation is likely to be more palatable for a broader segment of the banking industry, potentially paving the way for wider adoption of similar initiatives.
Furthermore, the focus on keeping tokenized deposits on bank balance sheets as liabilities is a critical factor. This preserves the fundamental nature of deposits as a source of stable funding for banks, which they can then deploy for lending activities. This is particularly important for regional banks that play a vital role in financing small businesses and local economic development. By tokenizing these deposits, banks can unlock new avenues for liquidity management and payment innovation without disrupting their core business model.
The involvement of prominent banks in the design and testing phases suggests a high level of confidence in the proposed solution. The active participation of institutions like Huntington Bancshares, First Horizon, M&T Bank, KeyCorp, and Old National Bancorp signals a united front in addressing the challenges and opportunities presented by digital assets. Their collective experience and insights are invaluable in shaping a network that is not only technologically sound but also practically viable and regulatory compliant.
The strategic alignment with ZKsync’s roadmap, which prioritizes privacy, control, and interoperability, further strengthens the long-term viability of this initiative. As regulatory clarity around digital assets continues to emerge, infrastructure designed with these principles in mind will be well-positioned to adapt and thrive. The ability to provide on-chain auditability while maintaining data privacy is a delicate balance that Prividium aims to achieve, addressing a key concern for financial regulators.
A Proactive Stance in a Shifting Financial Ecosystem
The move by Cari Network and its partner banks can be viewed as a proactive strategy to safeguard their market position and adapt to the changing dynamics of the financial ecosystem. As stablecoin issuers increasingly facilitate payments and attract deposit flows, traditional banks risk losing market share and customer relationships. By developing their own tokenized deposit network, they are taking control of the narrative and the technology, ensuring that they remain central players in the future of payments.
The creation of tokenized deposits, as opposed to simply issuing stablecoins, allows banks to leverage their existing regulatory licenses and customer trust. These tokens are essentially digital representations of existing fiat deposits, carrying the same guarantees and regulatory protections. This can offer a more familiar and secure entry point into the digital asset space for both banks and their customers.
The collaboration with Matter Labs, a company at the forefront of zero-knowledge technology, suggests a commitment to employing cutting-edge solutions. Zero-knowledge proofs, the underlying technology of ZKsync, offer the potential for enhanced privacy and scalability, which are crucial for enterprise-grade blockchain solutions. The ability of Prividium to offer instant settlement and robust auditability, while keeping sensitive data off-chain, addresses some of the key technical hurdles that have historically hindered institutional adoption of blockchain technology.
Looking ahead, the success of the Cari Network could serve as a blueprint for other regional and mid-sized banks seeking to modernize their operations. The ability to offer tokenized deposits could unlock new revenue streams, improve operational efficiency through faster settlements, and enhance customer engagement by providing more sophisticated payment options. The ongoing dialogue and development in this space underscore the transformative potential of blockchain technology to reshape the traditional banking landscape, enabling institutions to not only adapt but to thrive in the digital age. The strategic partnership between Cari Network and Matter Labs marks a significant stride in this ongoing evolution.
