by Jake ClaverQuick answer: DTCC Digital US Inc, part of the U.S. clearing and settlement giant DTCC, published two patent applications in March 2025: one for managing “digital liquidity tokens” on a distributed ledger, and one for hierarchical key management and delegated rights. Separately, DTCC unveiled a tokenized Collateral AppChain in April 2025. Together they show DTCC building tokenization infrastructure for regulated capital markets. These are patent filings and an in-development platform, not a shipped, live product.

When the company that clears most of the U.S. securities market files tokenization patents, it is worth reading the actual claims rather than the headlines. The Depository Trust and Clearing Corporation sits at the center of post-trade settlement, so its research direction is a useful signal of how tokenization might reach regulated markets, and where it might not.
This post works from the primary documents: two published patent applications on Google Patents, DTCC’s own platform announcement, and the Bank for International Settlements’ framing of tokenisation.
What DTCC Digital patented
Two applications, both assigned to DTCC Digital US Inc and naming the same inventor, George Daniel Doney, were filed on 20 November 2024 and published on 6 March 2025:
- US20250078162A1, “Systems, methods, and storage media for managing digital liquidity tokens in a distributed ledger platform.”
- US20250078065A1, “Method, apparatus, and computer-readable medium for confederated rights and hierarchical key management.”
A published application is a public record of what a company is trying to protect, not proof of a live system. It shows intent and design, which is exactly why it is worth reading carefully instead of over-reading.
What a digital liquidity token is, per the patent
The first patent describes “digital liquidity tokens” as instruments that represent liquidity functions between asset pairs on a distributed ledger. In the application’s own terms, the system covers tokenized asset pairs, automated market-making through token structures, fractional ownership using combinations of wrapped fungible and non-fungible tokens, and self-processing funds whose asset management is transparent on the ledger.
Put plainly, the filing is about packaging market-making and liquidity provision into on-ledger tokens so that liquidity providers can capture value and pricing stays continuous. That is a capital-markets plumbing idea, not a consumer product.
The Collateral AppChain
Alongside the patents, DTCC announced a tokenized real-time collateral management platform in April 2025, described on its Collateral AppChain page as a shared infrastructure layer for moving tokenized traditional and digital assets. The stated aim is near real-time, 24/7 collateral mobility across markets and time zones, so assets stop being trapped across institutions during margin calls.
DTCC said it is incorporating Chainlink’s Runtime Environment and data standard into the AppChain, with the platform expected to go live in Q4 2026. That is a development timeline, not a finished system, and it is worth stating that plainly.
The key-management patent and the custody problem
The second patent tackles a different problem: how to hold and delegate control of assets on a ledger without exposing the most sensitive keys. It describes a hierarchical wallet structure where an inactive “root wallet” can delegate signing authority to operational wallets and revoke or reassign that authority if one is compromised.
The application frames this as solving a “custody paradox,” the tension between keeping a wallet secure by rarely using it and keeping it useful by transacting often. For an institution moving tokenized collateral, recoverable and revocable control is arguably as important as the tokenization itself.
Why this matters
The BIS has argued that tokenisation could reshape the monetary and financial system by putting assets and their servicing logic on a shared ledger. DTCC’s patents and its Collateral AppChain are concrete examples of that idea being built by an incumbent market-infrastructure operator, from issuance-style tokenization through settlement and collateral movement.
A caveat for honest reading: the patents name no public cryptocurrency, and the AppChain’s disclosed technology partner is Chainlink. Do not read these documents as evidence for any specific token integration unless the source text says so. The tokenization-infrastructure story and any investment story are separate, and none of this predicts the price of anything.
Common questions
What is a DTCC digital liquidity token?
In DTCC Digital’s patent application US20250078162A1, a digital liquidity token is an on-ledger instrument representing liquidity functions between asset pairs, supporting automated market-making, fractional ownership through wrapped token combinations, and transparent, self-processing funds. It is a capital-markets infrastructure concept described in a patent, not a consumer token.
Who filed the DTCC digital liquidity token patents?
Both patent applications are assigned to DTCC Digital US Inc and name inventor George Daniel Doney. They were filed on 20 November 2024 and published on 6 March 2025.
What is the DTCC Collateral AppChain?
Announced in April 2025, the Collateral AppChain is DTCC’s tokenized collateral-management platform, designed as a shared infrastructure layer for near real-time, 24/7 movement of tokenized traditional and digital assets. DTCC is incorporating Chainlink’s Runtime Environment, and the platform is expected to launch in Q4 2026.
Do these patents mention a specific cryptocurrency?
No. The patents name no public cryptocurrency, and the AppChain’s disclosed technology partner is Chainlink. They should not be read as evidence for any particular token integration.
