DTCC Pilots Near-Instant Repo Settlement Using The Graph Protocol

Key Facts

1DTCC piloted near-instant repo settlement (T+5 seconds) using blockchain rails.
2The Graph's (GRT) subgraphs were utilized to power the critical data layer for the experiment.
3The project, known as the 'Great Collateral Experiment,' aims to improve collateral management efficiency.

The Depository Trust & Clearing Corporation (DTCC) has successfully piloted a blockchain-based system to settle repo transactions in just 5 seconds. Known as the 'Great Collateral Experiment,' the project utilized The Graph (GRT) subgraphs to power its critical data indexing layer. This initiative aims to modernize financial market infrastructure by shifting from traditional settlement cycles to near-instant blockchain-based processes. By drastically reducing transaction times, the system significantly lowers counterparty risk and enhances overall market liquidity. The involvement of DTCC, a cornerstone of global finance, provides major institutional validation for the utility of The Graph in real-world applications. This pilot marks a significant step forward in integrating decentralized protocols within mainstream institutional financial operations.
