DTCC Launches Securities Tokenization Service, Initially Supporting 34 Securities DTCC's website shows its tokenization service is now live, initially supporting 34 securities, including select components of the Russell 1000, ETFs and US Treasuries. Tokens are backed 1:1 by the underlying securities held in custody by the Depository Trust Company (DTC), carry the same legal and ownership rights, and support round-the-clock network transfers between DTC-registered wallets. The service initially supports Canton Network's private network and DTCCs Besu, with Star and Rainbow Circles expected to do so.
