DTCC confirmed on Oct 28 that its Tokenization Service is live, posting "The DTCC Tokenization Service is now live, and this is only the beginning" with a link to the service page The_DTCC.
The service page says 34 securities are available to tokenize at launch, about $30 trillion in assets under custody at DTC, 1:1 backing by securities held at DTC, and 24/7 intra-chain peer-to-peer transfers between DTC-registered wallets DTCC Tokenization page.
WuBlockchain reported the launch scope as selected large-cap Russell 1000 constituents, ETFs and U.S. Treasuries, with the same legal and ownership rights as the underlying, initially on Canton Network and DTCC's Besu-based private network, with Stellar and Circle's Arc expected in 2027 WuBlockchain.
Cointelegraph framed it as the $114T+ custodian launching with 34 securities at launch Cointelegraph. The page itself carries no timestamp, so Oct 28 is the date the change was read, not a date DTCC printed.
