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 typical that lets issuers embed id checks and switch restrictions into tokenized securities.
Zama, which raised $73 million in Collection A funding in 2024 to commercialize totally homomorphic encryption (FHE), stated the mixing is geared toward making confidentiality a built-in a part of tokenized asset infrastructure moderately than an add-on layered over current methods.
The businesses stated the mixing 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 business debate over how establishments ought to deal with privateness onchain, with zero-knowledge methods, permissioned networks and FHE all competing to change into a part of the tokenization stack.

Institutional customers “protect” ERC‑3643 positions
Zama founder Rand Hindi advised 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 described T-REX Ledger as a impartial infrastructure layer constructed round ERC-3643, the place id and rules-based compliance sit in good contracts and underlying Know Your Buyer knowledge stays offchain, enabling issuers to maintain parameters akin to 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 moderately than separate silos.
Competing privateness fashions are rising
The mixing comes as infrastructure suppliers debate how establishments ought to deal with privateness and interoperability onchain.
Matter Labs CEO Alex Gluchowski advised Cointelegraph that zero-knowledge methods like zkSync’s Prividium have been “the one means” that enterprises might “obtain actual privateness and onchain interoperability,” significantly when they need personal environments that may nonetheless settle atomically through Ethereum and different ZK domains.
He stated 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 crucial for many real-world belongings and stated 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 methods 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 directly, as an alternative 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 akin to confidential, compliant decentralized finance primitives or every 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.
