Paris, France, March 26, 2026 - T-REX Network, a multi-chain orchestration layer for real-world asset (RWA) tokenization, has formed a partnership with Zama to integrate native confidentiality into the T-REX Ledger using Fully Homomorphic Encryption (FHE). The collaboration brings Zama's encryption protocol into a ledger designed around the ERC-3643 compliance standard, which currently underpins $32 billion of tokenized assets, and aligns with Apex Group's decision to adopt the T-REX Ledger as its default infrastructure with a target of $100 billion in tokenized assets by June 2027.
This integration is positioned as a response to a persistent barrier for institutional use of public blockchain infrastructure: the public visibility of transactions, balances, and positions. For regulated market participants, public transparency presents unacceptable exposure of investor data, portfolio positions, and trading strategies. Historically, such institutions have turned to private blockchains to regain control and confidentiality, but those approaches often produce siloed systems with limited interoperability and reduced efficiency.
Why confidentiality at the token level matters
The T-REX Ledger is built as a neutral Layer 2 focused on compliant and interoperable digital securities. It aims to serve as a canonical source of truth across multiple blockchains for tokens issued under ERC-3643, unifying identity, compliance, and cross-chain interoperability into a single infrastructure. By embedding confidentiality directly into the ledger, T-REX and Zama seek to allow institutions to leverage public blockchains while meeting the privacy standards expected in regulated financial markets.
Zama's FHE protocol enables computation on encrypted data, allowing smart contracts to execute logic without ever decrypting the underlying confidential inputs. In practice, that means institutions could issue, manage, and settle tokenized assets on public T-REX blockchains without exposing sensitive information to outside observers - preserving operational discretion that would otherwise force them off public rails.
Technical and market implications
The partnership grew out of work inside the ERC3643 association, where participants have been addressing compliance and identity standards for regulated tokenization. Integrating Zama's FHE into the T-REX Ledger is presented as a way to retain the efficiency and interoperability of public infrastructure while meeting regulatory confidentiality needs. According to the announcement, this approach produces a scalable, privacy-preserving, and compliant foundation intended for institutional finance to operate onchain.
Joachim Lebrun, Co-Founder of T-REX Network and Lead Author of the ERC-3643 standard, said: "The T-REX Ledger was built to be the trusted multi-chain orchestration layer for institutional RWAs, but trust also means privacy. Integrating Zama's FHE Protocol directly into the T-REX Ledger means institutions can finally operate fully onchain without exposing their confidential data to the world. That is the missing piece for unlocking real institutional scale."
Dr. Rand Hindi, Co-Founder and CEO of Zama, added: "Our goal is to make Zama the confidentiality layer for public blockchains, enabling institutions and investors to operate onchain with the same level of privacy they expect offchain. This collaboration with T-REX Network demonstrates that confidentiality is not an optional feature for institutional blockchain adoption - it is foundational infrastructure. Together, we are enabling digital asset markets to scale securely, efficiently, and with trust."
Institutional confidentiality treated as shared infrastructure
By embedding the FHE layer into the ledger itself rather than delivering confidentiality as a bolt-on feature, the partners intend to make privacy a core piece of the tokenization stack. The announcement frames this approach as moving regulated institutions away from isolated private chains and toward interoperable public ecosystems where compliance, confidentiality, and identity live at the token level.
The project positions the T-REX Ledger as a neutral, interoperable compliance layer that connects ERC-3643 assets to compatible applications through the T-REX AppStore and offers a path for regulated assets to access liquidity across chains without sacrificing compliance controls. The integration with Zama is described as enabling confidential settlement and trade workflows at scale while retaining the cross-chain benefits of public ledgers.
Organizational context
According to the release, T-REX Network is the largest ecosystem for compliant RWA tokenization built on ERC-3643, with more than $32 billion in assets tokenized. T-REX's stated mission is to scale tokenization across blockchains without breaking compliance, using the T-REX Ledger as a cross-chain compliance reference layer and the T-REX AppStore to connect assets to natively compatible applications.
Zama is described as a cryptography company focused on building Fully Homomorphic Encryption solutions for blockchain, enabling confidentiality on public chains and supporting developers building confidential applications. The company was founded by Dr. Pascal Paillier and Dr. Rand Hindi and reportedly maintains a large team of FHE researchers and engineers.
