BitGo and ZKsync Begin Testing On-Chain Bank Deposit Platform
Digital asset custodian BitGo has partnered with Matter Labs to develop and test a full-stack infrastructure for tokenized bank deposits. The collaboration combines BitGo's institutional-grade custody and wallet services with Prividium, a permissioned, privacy-preserving blockchain from the creators of ZKsync. This joint offering is designed to allow banks to issue, transfer, and settle tokenized deposits while maintaining full compliance and control within established regulatory boundaries.
Unlike stablecoins, which operate outside the traditional banking system, tokenized deposits keep funds within regulated financial institutions. This structure enables programmable transactions and other blockchain-based features without altering existing compliance frameworks. The platform is currently being tested with financial institutions, with a broader production rollout anticipated later this year.
Tokenized deposits represent how banks bring money onchain without leaving the regulatory system.

New Infrastructure Enters Crowded Field for Institutional Privacy
The partnership places ZKsync's technology in direct competition with other solutions vying to solve the privacy and compliance challenges for institutions moving assets on-chain. The industry is currently debating the merits of different privacy models, including zero-knowledge (ZK) systems, permissioned networks, and Fully Homomorphic Encryption (FHE). For example, cryptography firm Zama recently integrated its FHE protocol with the T-REX Ledger to offer confidentiality for tokenized assets.
ZK-proof systems like Prividium aim to provide privacy by allowing institutions to prove transactions are valid without revealing sensitive underlying data, anchoring security to a public base layer like Ethereum. This contrasts with FHE, which allows computations on encrypted data. The BitGo-ZKsync initiative represents a significant bet that a ZK-based, permissioned environment offers the right balance of privacy, interoperability, and regulatory adherence needed to attract major financial institutions to the tokenization market.
