DTCC says commercial access to its Tokenization Service opens at the end of this month. In an update posted October 16, the post-trade giant described a launch of 25 initial securities, each backed one-to-one by a security held at its Depository Trust Company (DTC) unit, drawn from an eligible asset pool of roughly $30 trillion — about a quarter of what DTC holds in custody.
Some outlets have already described the service as launched. DTCC's own update, as reported by A-Team Insight and Crypto Briefing, points to the end of October, and we have not seen DTCC announce a go-live date. We will update this article when it does.
What Launches
The first 25 securities are select large-cap Russell 1000 stocks, select ETFs and a chosen set of Treasury bills, notes and bonds. The tokens carry the same CUSIP numbers, rights and investor protections as the book-entry securities they mirror, and DTC keeps the official books and records.
How It Works
Participants place conversion orders through a user interface or API between 2 a.m. and 6 p.m. ET on business days, with a processing target of 15 minutes or less. Once converted, tokens can move around the clock — but only within the same chain and only between DTC-registered wallets.
The service is built on DTCC's ComposerX application suite and its Compliance Aware Token Framework. Compliance rules sit in the token's smart contract code using the ERC-3643 standard, and the tokens are ERC-20 compatible. Crypto Briefing notes that a token on Canton cannot simply hop to a wallet on Besu at launch.
Networks, and Why Early Reporting Differed
At launch the service runs on Digital Asset's Canton Network and DTCC's own private Hyperledger Besu network. For 2027, DTCC plans support for two public networks: Stellar and Circle's recently launched Arc.
Reporting before the update — including The Block's October 8 briefing and the first version of this article — listed Stellar and DTCC's Collateral AppChain among the eligible networks. The October 16 update lists Canton and Besu at launch, with Stellar following in 2027. The Block had reported the AppChain as expected later this year; we have not seen DTCC place it in this launch.
Who Has Tested It
On July 15, more than 30 firms from traditional finance and digital asset markets converted DTC-held securities into tokens and used them in live trades in DTC's production environment. The workflows included collateral pledges, securities lending, Treasury and repo delivery-versus-payment, equity delivery-versus-payment, and central counterparty margin. The conversions ran on both Besu and Canton.
DTCC's industry working group, announced in May, has more than 50 members; BlackRock, JPMorgan and Goldman Sachs are among those reported as members. Working-group membership is not the same as using the service at launch, and the reporting we reviewed does not include a list of firms that will.
The Scale: What the Numbers Do and Don't Say
DTC holds about $114 trillion in custody. The whole tokenized real-world asset market is about $38.8 billion, per The Block's October 8 briefing — roughly 0.03% of that custody pool. The Block's illustration: if participants tokenized just 0.5% of the $114 trillion, that would add about $570 billion.
The initial eligible pool is smaller than the custody total. On the $30 trillion pool, the same 0.5% is about $150 billion (RWAToday arithmetic) — still nearly four times today's entire market. These are illustrations, not forecasts; nobody has said what share will actually be tokenized.
On efficiency, Digital Asset's Kelly Mathieson told Markets Media that institutions estimate the service could improve balance sheet efficiency by 30% to 50%. Those are industry estimates, not DTCC figures.
What It Is Not
Not a new asset. The tokens mirror securities already held at DTC. Not retail. Wallets must be DTC-registered, which limits use to DTC participants. Not on public chains at launch. Canton and Besu are the two networks. Not round-the-clock conversion. The conversion window is 2 a.m. to 6 p.m. ET; the 24/7 part is transfers. Not permanent authorization. Crypto Briefing reports DTCC has until late 2028 under its current SEC no-action framework to show the model works.
One nuance worth noting: DTCC itself describes its tokens as digital twins of the underlying securities, with DTC remaining the official record. That sits on the other side of the line Franklin Templeton CEO Jenny Johnson drew at TOKEN2049 between funds that use a blockchain as the real system of record and those that use it as a copy (our recap). It makes DTCC's design a useful test of how much that distinction matters to institutions in practice.
The 2027 Roadmap
DTCC's update lays out the next phase: public network support for Stellar and Arc; stronger security controls including single sign-on and maker-checker approvals; a consolidated stock record that merges book-entry and on-chain positions; more eligible DTC participants; the full Russell 1000, more ETFs and broader Treasury coverage; and, further out, digital cash integrations, on-chain netting for settlement and collateral, and expanded corporate action servicing for equities and ETFs.
What to Watch
The go-live confirmation itself. Which firms use the service first, and how quickly activity grows beyond the 30-plus that tested it. Whether tokens can ever move between Canton and Besu. And how the SEC's no-action framework is treated as the three-year clock runs.
