T-REX Network is a real-world asset tokenization project that is building its dedicated T-REX ledger using Polygon's CDK and AggLayer. The ledger is designed to serve as a shared compliance layer for interoperable blockchains, ensuring compliance in token issuance and transfers through embedded ERC-3643 standard rules. Tokeny, a subsidiary of Apex Group and creator of the ERC-3643 standard, provides support for the ledger's construction, while Apex serves as the initial on-chain transfer agent. Over 140 institutions support the ERC-3643 standard, and Tokeny's T-Rex Factory has facilitated the issuance of nearly 150 tokens with a cumulative value exceeding $32 billion.
