The Depository Trust & Clearing Corporation, the backbone of US securities settlement, is building a blockchain-native collateral management platform powered by Chainlink. The system, called Collateral AppChain, is designed to address the cost, valuation, and long-term stability of global markets.
What DTCC is doing
Collateral AppChain integrates Chainlink’s Runtime Environment, known as CRE, to automate workflows that have traditionally relied on manual systems. Instead of people sorting through spreadsheets and making phone calls to confirm the price of a commodity in regular sessions, smart contracts automatically manage prices and returns.
The platform is designed to operate 24/7, a departure from the traditional financial world where collateral management is often constrained by business hours and geographic boundaries. The goal is long-term mobility on different blockchains and global markets.
DTCC revealed this on May 12, 2026, during what the company calls the Great Collateral Experiment. Collateral AppChain is expected to launch in Q4 2026.
Nadine Chakar, Managing Director of DTCC, created a partnership around the transformative potential of onchain interactive data. This vision is an area of development that many people involved in the environment, think that banks, asset managers, asset managers, can connect instead of everyone keeping their own systems.
This problem solves
The global market is now around $15 trillion. Collateral management today involves a combination of intermediaries, distributed data sources, and processes that were developed before the Internet era. When a bank needs to post collateral for an outbound transaction, the verification, calculation, and transfer can take hours or days.
This is not DTCC’s first foray into blockchain and Chainlink. The two organizations agreed on the Smart NAV initiative in 2024, which brought mutual fund net value asset data onchain. The original project appears to have served as proof of the deep integration now being released by Collateral AppChain.
Where this is related to the tokenization feature
The issue of using collateral is very important because it affects almost all aspects of corporate finance. Derivative markets, repo agreements, securities lending: all of these depend on proper management.
Chainlink’s CRE provides DTCC with access to reliable price feeds and centralized connectivity, especially pipelines that make multi-chain collateral possible. DTCC handles 99% of the US security every day, making it one of Chainlink’s most important acquisitions.
