Chainlink partnered with DTCC at SIBOS 2026 to enhance collateral management systems and support greater mobility for tokenized securities. Sergey Nazarov and Nadine Chakar discussed how the DTCC Collateral AppChain, an application-specific blockchain, could create new opportunities for digital securities. Discussions also centered on Chainlink’s Fulcrum technology, which enables cross-chain securities financing. Chainlink’s recent tweet presented the collaboration as potentially significant for the interaction between traditional finance and digital assets, while the broader initiative is expected to modernize financial infrastructure and improve longstanding collateral-management inefficiencies.
