Twenty firms have signed up, and the custodian behind $114 trillion in assets is now open for business on-chain. On Wednesday, the Depository Trust Company (DTC) announced that its tokenization service is live. DTC is the settlement and custody arm of the Depository Trust & Clearing Corporation (DTCC). Eligible clients can now mint tokenized representations of securities that DTC holds for them.

That is a large sentence for a market that has spent years on pilots and press releases. I'd read it slowly. The details are narrower than the headline.

One caution on the $114 trillion figure: it describes what DTCC's custody business holds in total. It is not the amount that will be tokenized. Nobody has said what share of it will ever be minted, and the announcement doesn't claim otherwise.

What actually went live

The product is the DTCC Tokenization Service, or DTS. According to the company's announcement, as Cointelegraph reported, it converts securities between their conventional form and a tokenized one. The tokenized form can be moved to digital wallets. DTCC's position is that a holder of the token keeps the ownership rights and investor protections attached to the traditional entry.

The mechanics matter. DTS creates no new asset class. It adds a second wrapper to securities already sitting in DTC's vaults, stocks and exchange-traded funds among them. The underlying position stays put. The token represents it and does the travelling.

That design is conservative on purpose. A token that mirrors a position in an existing, regulated custody system inherits that system's legal footing. The trade-off: the token is only as independent as the ledger behind it. If DTC's records and the chain ever disagree, DTC's records win. Compliance officers will call that a feature. Anyone hoping for fully self-contained on-chain assets will call it a limitation.

Access is restricted to DTCC clients, so retail investors cannot deal with DTC directly. The plumbing has never worked that way. Ordinary investors will get exposure through brokers and platforms, if they get it at all.

Who signed, and who didn't say

DTCC named only some of the 20 clients that have signed agreements. The disclosed group splits roughly into three types:

  • Large banks: JPMorgan and Citi.
  • Trading and custody heavyweights: Citadel Securities, a market maker, and Fidelity Investments, a brokerage giant that also acts as a custodian.
  • Infrastructure and brokerage specialists: Alpaca, Clear Street, DriveWealth and Interchange Clearing, several of which sell brokerage plumbing to apps and smaller platforms.

The mix is sensible. Banks bring balance sheets, the market maker brings liquidity, and the infrastructure firms bring distribution to retail front-ends. Roughly half the roster, 12 of the 20, remains unnamed, so the picture is incomplete.

Signing an agreement is not the same as moving volume. DTCC hasn't published figures on how much will be minted, by whom, or when, and nobody has said which securities go first. Those are the numbers I'd chase over the next two quarters. An agreement costs nothing; a live mint does.

The road from no-action letter to launch

The regulatory groundwork came first. Back in December 2025, SEC staff sent the DTC subsidiary a no-action letter on its planned tokenization program. Translation: staff would not urge the Commission to pursue enforcement if DTC ran the program as described. That is staff-level comfort, not a rule, and it can be narrow. It binds neither the Commission's later views nor a future administration's. Still, it cleared the way for a project that would have been hard to ship under a cloud.

The schedule has held. In May, DTCC said it intended a full launch of tokenized securities trading in October 2026, after a pilot in July. Wednesday's announcement lands inside that window. For an institution whose reputation rests on not breaking things, hitting a stated month is worth a line.

Two chains now, more promised

The service currently runs on the Canton Network and on DTCC's own Besu private network. Canton is built for regulated institutions that want privacy between counterparties. Besu is an Ethereum-compatible client, deployed here in a permissioned setup that DTCC operates itself.

Neither is a public chain in the sense a DeFi user would mean. That is a design choice, and a predictable one. Permissioned networks let a custodian control who participates, which is close to a precondition for a regulated utility.

DTCC says more blockchain networks will be added in 2027 but hasn't said which. My read: that list will be the first real signal of how open the system intends to be. A roster of permissioned networks would keep tokenized Wall Street fenced off from the wider crypto economy. A public network on it would change the conversation.

That is speculation. DTCC has committed to nothing beyond the 2027 timeframe.

The interoperability problem

Two chains on day one already raise a practical question: can a token minted on one be used on the other? The announcement, as reported, doesn't say. If each network is its own closed pool, a firm minting on Canton may find its counterparty is on Besu, and the efficiency argument for tokenization weakens quickly. Faster settlement only helps when both sides of the trade can reach the same ledger, or when DTC can bridge them reliably.

This is not a criticism so much as the obvious next engineering test. Conversion between conventional and tokenized form is the easy part, since DTC controls both ends. Moving value between independent networks is where most tokenization pilots in the industry have struggled, and DTCC will be judged on it.

What to watch

Three things. First, whether the 20 signatories start minting, and in what size. Second, whether those tokens can settle against each other across firms and chains, or whether each participant ends up with an isolated pool. Third, the 2027 network additions.

The company calls this a "practical path" for tokenized securities adoption. Practical is the right word, and a modest one. The pipes are built. The biggest names have their hands on the valves. Whether anything meaningful flows through them is the open question heading into next year.
