PANews, March 21 news, according to Cointelegraph, according to an announcement dated March 20, the main clearing agency for US securities trading - the Depository Trust & Clearing Corporation (DTCC) has pledged to promote the ERC-3643 standard of Ethereum for permissioned security tokens. DTCC will join the ERC3643 Association, a non-profit organization dedicated to promoting the adoption of this standard, with the goal of "promoting and advancing the ERC3643 token standard". This support highlights the positive attitude of US regulators towards tokenization, after President Trump's pledge to make the US a "global crypto capital". It also indicates that the Ethereum blockchain network may play an important role in the permissioned security token ecosystem in the US.

ERC3643 Association Chairman Dennis O'Connell said in a statement: "DTCC will help lead the future of tokenization and support large-scale institutional adoption." ERC-3643 is also known as the T-REX protocol, and according to the ERC3643 Association website, it is "a set of open-source smart contracts that support the issuance, management and transfer of permissioned tokens... even on permissionless blockchains". It relies on a custom decentralized identity protocol to ensure that only users who meet pre-set conditions can become token holders.
