DTCC, the post-trade infrastructure provider behind the US securities clearing system, will use Chainlink's Runtime Environment and data standard to run its Collateral AppChain — a Besu-based blockchain that tokenizes collateral and automates pricing, valuation, margining and settlement. The platform is designed to move assets 24/7 across both traditional markets and blockchain networks, replacing workflows that today leave collateral trapped across institutions and time zones.
The integration extends a 2024 Smart NAV pilot in which DTCC, JPMorgan, BNY Mellon and Franklin Templeton pushed mutual fund net asset value data on-chain via Chainlink. DTCC managing director and global head of digital assets Nadine Chakar framed the build-out as a structural modernisation push, not a point experiment.
Why it matters
DTCC's subsidiaries processed $4.7 quadrillion in securities transactions in 2025, and its depository provided custody and asset servicing for $114 trillion in securities. Putting Chainlink's oracle layer inside that pipeline means real-world price, valuation and eligibility data gets pushed directly into automated collateral workflows — the kind of plumbing that until now has lived in batched, hours-old reconciliation cycles. Chakar said the goal is "24/7, near real-time collateral management across global markets and blockchains."
For Chainlink, the deal is one of its highest-profile enterprise validations to date, threading its data and orchestration stack into a system that touches almost every major US securities transaction.
Market impact
The Chainlink integration is one thread of a broader DTCC tokenization push. The company said earlier this month that more than 50 firms had joined a working group for a separate tokenization service, with limited production trades slated for July and a full launch targeted for October.
