Chainlink collaborates with DTCC on 24/7 collateral management via new AppChain

The Depository Trust & Clearing Corporation announced on May 12, 2026 that it will integrate Chainlink’s Runtime Environment into its new Collateral AppChain platform, aiming to bring round-the-clock, near real-time collateral management to financial markets that currently run on systems built decades ago.

To put DTCC’s scale in perspective: it processed $4.7 quadrillion in securities transactions during 2025 and holds custody of $114 trillion in assets from investors across more than 150 countries.

What the Collateral AppChain actually does

The Collateral AppChain is built on Hyperledger Besu, a permissioned blockchain, and will use Chainlink’s Runtime Environment to handle orchestration and data feeds across the platform. In practice, that means Chainlink’s infrastructure will coordinate the flow of information between different blockchains and financial systems.

Automated workflows will cover the full collateral lifecycle: eligibility checking, valuation, margin calculation, optimization of which assets to post where, and final settlement. The goal is to compress what currently takes hours or days into something that runs continuously, around the clock.

DTCC has set a target launch window of Q4 2026 for the platform.

Why this partnership makes sense for both sides

In 2024, Chainlink participated in a Smart NAV pilot alongside JPMorgan, BNY Mellon, and Franklin Templeton, which explored delivering mutual fund net asset value data onto blockchain networks.

DTCC’s decision to build on Hyperledger Besu rather than a public blockchain reflects the institutional reality: permissioned systems with known participants are still the comfort zone for regulated financial entities. But the Chainlink integration is designed to bridge that permissioned environment with the broader blockchain ecosystem, meaning the AppChain does not have to exist in isolation.
