The Depository Trust & Clearing Corporation (DTCC) will use Chainlink infrastructure for its blockchain-based collateral management platform, extending previous work between the companies into one of Wall Street’s primary risk management functions.
The company said its AppChain Collateral will use Chainlink’s Execution Environment (CRE) and data standard to support collateral pricing, valuation, margining, optimization and settlement. AppChain is a Besu-based blockchain platform that facilitates asset tokenization and collateral management in real-time, 24/7.
DTCC’s platform aims to reduce delays and fragmentation in current collateral systems, where assets are often trapped between institutions and time zones. By tokenizing collateral and automating workflows via smart contracts, the system is designed to enable near real-time movement of collateral across traditional financial markets and blockchain networks.
“By leveraging tokenization and distributed ledger technology (DLT) to modernize collateral mobility, our goal is to enable 24/7, near real-time collateral management across global markets and blockchains,” said Nadine Chakar, DTCC Managing Director and Global Head of Digital Assets.
Chainlink will provide the data and orchestration layer. Its technology will help connect asset prices, valuations and collateral movements, while supporting eligibility checks, margin and settlement instructions. Chainlink is a decentralized oracle network that powers blockchains with real-world data such as prices, weather, and APIs, as blockchains cannot natively access external information on their own.
The platform operates in DTCC’s AppChain setup. DTCC unveiled the tokenized collateral platform last year, saying collateral mobility could become a key institutional use case for blockchain technology.
The tie-up with Chainlink builds on Smart NAV, a 2024 pilot project in which DTCC and Chainlink tested the integration of mutual fund net asset value data on blockchains.
JPMorgan, Franklin Templeton and BNY Mellon participated in the pilot, focused on tokenizing funds across multiple chains.
DTCC has also expanded its tokenization work beyond collateral. The company said earlier this month that more than 50 companies had joined a working group for The Depository Trust Company’s tokenization service, with limited production swaps planned for July and a launch planned for October.
DTCC subsidiaries processed $4.7 billion in securities transactions in 2025. Its depository subsidiary provided custody and asset management for securities issuances valued at $114 trillion.
