The Depository Trust & Clearing Corporation, the backbone of U.S. securities settlement, is building a blockchain-native collateral management platform powered by Chainlink. The system, called Collateral AppChain, is designed to handle the pricing, valuation and settlement of assets in international markets 24 hours a day.
What DTCC is actually building
The Collateral AppChain integrates Chainlink’s Runtime Environment, known as CRE, to automate collateral workflows that have traditionally relied on manual processes. Instead of people mixing up spreadsheets and making calls to verify the value of assets across time zones, smart contracts handle pricing and settlement automatically.
The platform is designed to operate 24/7, a meaningful departure from the traditional financial world where collateral management is typically limited by business hours and geographic boundaries. The goal is near real-time movement of collateral across different blockchains and international markets.
DTCC unveiled the initiative on May 12, 2026, during what the company calls its Great Collateral Experiment. The Collateral AppChain is expected to launch in the fourth quarter of 2026.
Nadine Chakar, Managing Director of DTCC, framed the partnership around the transformative potential of unified onchain data. The vision is a shared infrastructure layer that multiple participants in the collateral ecosystem—think banks, asset managers, and custodians—can connect to, rather than each maintaining its own siled systems.
The problem this solves
The global collateral market is approximately $15 trillion. Collateral management today involves a maze of intermediaries, fragmented data sources, and processes designed for a pre-Internet age. When a bank needs to provide collateral for a derivatives trade, the chain of verification, valuation and transfer can take hours or even days.
This isn’t DTCC’s first foray into blockchain with Chainlink. The two organizations collaborated in 2024 on a Smart NAV initiative, which brought data on the intrinsic value of investment funds into the chain. That earlier project appears to have served as a testing ground for the deeper integration now being rolled out with the Collateral AppChain.
Where this fits into the tokenization wave
The use of collateral is particularly important because it touches almost every corner of institutional finance. Derivatives markets, repurchase agreements, securities lending: these all depend on efficient collateral management.
Chainlink’s CRE gives DTCC access to reliable price feeds and cross-chain communications, essentially the plumbing that makes a multi-chain collateral system feasible. DTCC processes 99% of US securities settlements every day, making it one of the most significant institutional endorsements Chainlink has secured.
