French cryptography startup Zama is integrating its protocol with Apex-backed T-REX Ledger so as to add a confidentiality layer for ERC-3643-based tokenized belongings, a regular that lets issuers embed id checks and switch restrictions into tokenized securities.
Zama, which raised $73 million in Series A funding in 2024 to commercialize totally homomorphic encryption (FHE), mentioned the combination is geared toward making confidentiality a built-in a part of tokenized asset infrastructure quite than an add-on layered over current programs.
The businesses mentioned the combination would enable regulated establishments to make use of public blockchain infrastructure with out exposing delicate positions and transaction knowledge, a sticking level that has slowed broader institutional use of public networks for regulated belongings.
The announcement lands amid a wider trade debate over how establishments ought to deal with privateness onchain, with zero-knowledge programs, 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 be capable of “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 described T-REX Ledger as a impartial infrastructure layer constructed round ERC-3643, the place id and rules-based compliance sit in sensible contracts and underlying Know Your Customer knowledge stays offchain, enabling issuers to maintain parameters reminiscent of rates of interest, withholding taxes or liquidation thresholds confidential on public rails.
Hindi argued that this eliminated the normal “commerce off” between regulatory compliance and confidentiality by pushing each into shared, programmable infrastructure quite 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 programs like zkSync’s Prividium had been “the one method” that enterprises may “obtain actual privateness and onchain interoperability,” significantly when they need non-public environments that may nonetheless settle atomically through Ethereum and different ZK domains.
He mentioned that ZK proofs had been designed to let establishments show transactions had 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 crucial for many real-world assets and mentioned Canton’s permissioned 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 programs nonetheless relied on authorized frameworks to resolve disputes over person intent.
Zama’s FHE pitch
Hindi positioned FHE as complementary to each approaches, claiming it solved the “shared state drawback that limits each ZK and Canton” by permitting the community to run shared computations over encrypted knowledge from many customers without delay, as a substitute of hiding knowledge by not sharing it or counting on every person to show their very own state.
That, he argued, made it attainable to implement workflows reminiscent of confidential, compliant decentralized finance 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.
