Zama taps Apex-backed T‑REX to bring bank‑grade privacy to public blockchains
French cryptography startup Zama is integrating its protocol with Apex-backed T-REX Ledger to grow to be what it calls the “default confidentiality layer” for ERC-3643 tokenized property, a typical that lets issuers embed id checks and switch restrictions into tokenized securities.
In keeping with a Tuesday launch shared with Cointelegraph, Zama, which raised $73 million in Sequence A funding in 2024 to commercialize totally homomorphic encryption (FHE), and T-REX Community intention to ascertain privateness as a core infrastructure for institutional tokenization, “reasonably than a standalone function.”
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 informed 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 says T-REX Ledger features as a impartial layer-2 constructed round ERC-3643, the place id and rules-based compliance sit in sensible contracts, and underlying Know Your Buyer (KYC) information 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 normal “commerce off” between regulatory compliance and confidentiality by pushing each into shared, programmable infrastructure reasonably than separate silos.
ZK and Canton’s competing visions
The mixing comes amid a broader debate over the best way to carry institutional-grade privateness and interoperability onchain.
Matter Labs CEO Alex Gluchowski informed Cointelegraph that zero-knowledge methods like zkSync’s Prividium had 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 (ETH) 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 information, whereas anchoring safety to Ethereum’s base layer.

Digital Asset co-founder Shaul Kfir disputed that ZK was crucial for many real-world property (RWAs) and argued that Canton Community, which makes use of a permissioned structure, already mixed privateness and interoperability by abandoning the idea that “everybody on the planet” 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 information from many customers directly, as an alternative of hiding information 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 each day threshold checks for regulators on public infrastructure, with just a few seconds of additional latency for encryption and decryption however no change to T-REX’s underlying throughput or public chain composability.
