French cryptography startup Zama is integrating its protocol with Apex-backed T-REX Ledger to turn into what it calls the “default confidentiality layer” for ERC-3643 tokenized belongings, a normal that lets issuers embed id checks and switch restrictions into tokenized securities.
In line with a Tuesday launch shared with Cointelegraph, Zama, which raised $73 million in Collection A funding in 2024 to commercialize totally homomorphic encryption (FHE), and T-REX Community purpose to determine privateness as a core infrastructure for institutional tokenization, “relatively than a standalone characteristic.”
The mixing, they are saying, will allow regulated establishments to make use of public blockchain ecosystems “with out compromising operational safety or market integrity,” a sticking level that has prevented many establishments from placing delicate positions and buying and selling methods on public rails.
Zama founder Rand Hindi instructed Cointelegraph that establishments utilizing T-REX would have the ability to “protect” current positions by wrapping ERC-3643 tokens into confidential equivalents, preserving balances 1:1 whereas encrypting future transfers and ensuing balances end-to-end.

Zama says T-REX Ledger capabilities as a impartial layer-2 constructed round ERC-3643, the place id and rules-based compliance sit in good contracts, and underlying Know Your Buyer (KYC) knowledge stays off-chain, enabling issuers to maintain parameters resembling rates of interest, withholding taxes, or liquidation thresholds confidential on public rails.
Hindi argued that this eliminated the standard “commerce off” between regulatory compliance and confidentiality by pushing each into shared, programmable infrastructure relatively than separate silos.
ZK and Canton’s competing visions
The mixing comes amid a broader debate over how you can convey institutional-grade privateness and interoperability onchain.
Matter Labs CEO Alex Gluchowski instructed Cointelegraph that zero-knowledge methods like zkSync’s Prividium have been “the one manner” that enterprises might “obtain actual privateness and onchain interoperability,” notably when they need personal environments that may nonetheless settle atomically by way of Ethereum (ETH) and different ZK domains.
He mentioned that ZK proofs have been designed to let establishments show transactions have been legitimate with out revealing the underlying knowledge, whereas anchoring safety to Ethereum’s base layer.

Digital Asset co-founder Shaul Kfir disputed that ZK was vital for many real-world belongings (RWAs) and argued that Canton Community, which makes use of a permissioned structure, already mixed privateness and interoperability by abandoning the belief that “everybody on the earth” should validate each transaction.
Kfir insisted that cryptographic ensures couldn’t “substitute for authorized enforceability,” pointing to onchain hacks as proof that institutional methods nonetheless relied on authorized frameworks to resolve disputes over consumer intent.
Zama’s FHE pitch
Hindi positioned FHE as complementary to each approaches, claiming it solved the “shared state downside that limits each ZK and Canton” by permitting the community to run shared computations over encrypted knowledge from many customers directly, as a substitute of hiding knowledge by not sharing it or counting on every consumer to show their very own state.
That, he argued, made it doable to implement workflows resembling confidential, compliant decentralized finance (DeFi) primitives or day by day threshold checks for regulators on public infrastructure, with a number of seconds of additional latency for encryption and decryption however no change to T-REX’s underlying throughput or public chain composability.
