French cryptography startup Zama is integrating its protocol with Apex-backed T-REX Ledger to add a confidentiality layer for ERC-3643-based tokenized belongings, an ordinary that lets issuers embed identification checks and switch restrictions into tokenized securities.
Zama, which raised $73 million in Series A funding in 2024 to commercialize absolutely homomorphic encryption (FHE), mentioned the mixing is meant to make confidentiality a built-in characteristic of tokenized asset infrastructure relatively than an added layer.
The combination is designed to enable establishments to use public blockchains with out exposing delicate positions and transaction knowledge, a problem that has restricted adoption of public networks for regulated belongings.
The announcement comes amid a broader trade debate over how establishments ought to deal with privateness onchain, with zero-knowledge techniques, permissioned networks and FHE all competing to develop into a part of the tokenization stack.

Institutional customers “protect” ERC‑3643 positions
Zama founder Rand Hindi instructed Cointelegraph that establishments utilizing T-REX would have the opportunity to “protect” present positions by wrapping ERC-3643 tokens into confidential equivalents, preserving balances 1:1 whereas encrypting future transfers and ensuing balances end-to-end.
Zama described T-REX Ledger as a impartial infrastructure layer constructed round ERC-3643, the place identification and rules-based compliance sit in good contracts and underlying Know Your Customer knowledge stays offchain, permitting issuers to maintain parameters corresponding to rates of interest, withholding taxes or liquidation thresholds confidential on public networks.
Hindi mentioned this might scale back the normal “trade-off” between regulatory compliance and confidentiality by pushing each into shared, programmable infrastructure relatively than separate silos.
Competing privateness fashions are rising
The combination comes as infrastructure suppliers debate how establishments ought to deal with privateness and interoperability onchain.
Matter Labs CEO Alex Gluchowski instructed Cointelegraph that zero-knowledge techniques like zkSync’s Prividium have been “the one approach” that enterprises may “obtain actual privateness and onchain interoperability,” notably when they need non-public environments that may nonetheless settle atomically by way of Ethereum 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 mandatory for many real-world assets and mentioned Canton’s structure already mixed privateness and interoperability with out requiring each participant to validate each transaction.
Kfir insisted that cryptographic ensures couldn’t “substitute for authorized enforceability,” pointing to onchain hacks as proof that institutional techniques nonetheless relied on authorized frameworks to resolve disputes over person intent.
Zama’s FHE pitch
Hindi positioned FHE as complementary to each approaches, saying it addresses what he described as a “shared state downside” affecting each ZK and Canton approaches by permitting networks to run computations on encrypted knowledge from a number of customers, relatively than counting on knowledge isolation or particular person proofs.
That, he argued, made it attainable to implement workflows corresponding to confidential, compliant decentralized finance primitives or each day threshold checks for regulators on public infrastructure, with a couple of seconds of additional latency for encryption and decryption, however no change to T-REX’s underlying throughput or public-chain composability.
