DTCC builds blockchain-based collateral system with Chainlink integration
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 the Collateral AppChain, is designed to handle asset pricing, valuation, and settlement around the clock across international markets. What DTCC is actually building The Collateral AppChain integrates Chainlinks Runtime Environment, known as CRE, to automate collateral workflows that have historically relied on manual processes. Instead of humans shuffling spreadsheets and making phone calls to verify asset values across time zones, smart contracts handle the pricing and settlement automatically. The platform is designed to operate 24/7, a meaningful departure from the traditional finance world where collateral management is typically constrained by business hours and geographic boundaries. The goal is near-real-time collateral movement across different blockchains and international markets. DTCC unveiled the initiative on May 12, 2026, during what the firm calls its Great Collateral Experiment. The Collateral AppChain is slated to launch in Q4 2026. Nadine Chakar, DTCCs Managing Director, framed the partnership around the transformative potential of unified onchain data.
