CMTA Launches CMTAT Confidential for Private Securities Tokenization

Swiss CMTA introduces CMTAT Confidential, leveraging Zama’s FHE to enable private balances and transfers for tokenized securities while retaining regulatory oversight.

Woofun AI reports that the Swiss Association for Capital Markets and Technology (CMTA) has launched CMTAT Confidential, integrating privacy features into its smart contract standard framework. Backed by the Zama Protocol, the upgrade ensures default privacy for investor account balances and transaction amounts within the existing CMTAT ecosystem used for equity and debt tokenization. The implementation preserves essential compliance controls, including whitelist systems and freezing mechanisms. Utilizing homomorphic encryption (FHE), the protocol allows smart contracts to process encrypted data without decryption, supplemented by multi-party computation and zero-knowledge proofs to maintain regulatory oversight. Geneva-based infrastructure firm Taurus developed the code, which has undergone security audits by OpenZeppelin.
