Blockchain solutions provider Digital Asset and the Depositary Trust and Clearing Corporation (DTCC) recently completed a pilot project to tokenize US Treasury collateral on the Canton network. The project involved 26 market participants and completed 100 transactions, with the aim of improving settlement speed, ensuring privacy and complying with legal requirements. In the pilot, participants converted US Treasury bonds (UST) into "digital twin" tokens for use in multiple scenarios, including trading, collateralization, and default processing. The system allows for immediate asset transfers when margin notifications are made, and all transactions are traceable and auditable. Even in the event of an investor default, relevant parties can quickly transfer assets according to the law to ensure the safety of transactions. This project showcases the technical advantages of the Canton network, particularly innovations in transaction privacy and legal compliance, driving the adoption of tokenized assets in financial marekt.
