About Cobalt

Harnessing the potential of distributed ledger technology, Cobalt delivers a private peer-to-peer network that significantly reduces post-trade cost and risk for financial market participants.

Legacy infrastructure is duplicative, inefficient and unfit for today’s market. A single trade creates multiple records for all parties. Cobalt’s technology leverages blockchain-derived concepts of encryption, digital signatures and consensus to deliver a single, immutable record for each trade. By creating a shared view of trade data, Cobalt frees up back and middle office resources from multiple layers of reconciliation.

With no legacy infrastructure to protect, Cobalt is taking a fresh approach to post-trade technology. This is the future of financial services infrastructure: signed, sealed, delivered.
