OpenZeppelin and T-REX Network announced on July 7, 2026 a strategic partnership to strengthen the infrastructure behind the ERC-3643 standard, used for regulated tokenized securities. The two companies are working on ONCHAINID v3, a modular identity layer based on the ERC-7579 standard and ERC-4337 account abstraction. Over $32 billion in assets have already been tokenized under this standard across more than 20 jurisdictions. The T-REX Ledger, designed as a cross-chain compliance framework via Polygon CDK, is expected to launch on mainnet in Q4 2026. Apex Group, an asset manager overseeing approximately $3.5 trillion in assets, has committed to deploying this infrastructure with the goal of tokenizing up to $100 billion in assets by June 2027.
