Depository Trust & Clearing Corporation (DTCC) will use Chainlink infrastructure for its blockchain-based collateral management platform, expanding previous work between firms into one of Wall Street’s core risk management functions.
The firm said its Collateral AppChain will use Chainlink’s execution environment (CRE) and data standard to support pricing, valuation, margining, collateral optimization and settlement. AppChain is a Besu-based blockchain platform that facilitates real-time, 24/7 asset tokenization and collateral management.
DTCC’s platform aims to reduce delays and fragmentation in current collateral systems, where assets are often stuck between institutions and time zones. By tokenizing collateral and automating workflows through smart contracts, the system is designed to enable near real-time movement of collateral across both traditional financial markets and blockchain networks.
“By leveraging tokenization and distributed ledger technology (DLT) to modernize collateral mobility, we aim to enable 24/7, near real-time collateral management across global markets and blockchains,” said Nadine Chakar, CEO of DTCC and Global Head of Digital Assets.
Chainlink will provide the data and orchestration layer. Its technology will help connect asset prices, valuations and collateral movement, while supporting eligibility checks, margins and settlement instructions. Chainlink is a decentralized oracle network that feeds blockchains with real-world data such as prices, weather, and APIs, since blockchains cannot natively access external information on their own.
The platform runs within DTCC’s AppChain setup. DTCC unveiled the tokenized collateral platform last year and said collateral mobility could become a key institutional use case for blockchain technology.
Chainlink’s partnership builds on Smart NAV, a 2024 pilot in which DTCC and Chainlink tested adding mutual fund net asset value data to blockchains.
JPMorgan, Franklin Templeton, and BNY Mellon participated in the pilot, which focused on tokenizing funds across multiple chains.
DTCC has also been expanding 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 operations planned for July and a launch planned for October.
DTCC’s affiliates processed $4.7 trillion in securities transactions in 2025. Its depository subsidiary provided custody and asset services for securities issuances valued at $114 trillion.
