Use Cases

SETL's OpenCSD platform can be used in a variety of implementations - both private and co-operative.


Mutual Funds

The maintenance of registers for mutual funds is currently handled in a disparate and bespoke manner depending upon the jurisdiction and the arrangements of the fund management company. OpenCSD could be used to standardise and streamline ownership, issue and redemption records.


Cross Border

Securities which currently trade across different jurisdictions and exchanges are often subject to settlement in local silo's based on currency or technical inflexibility. This can fragment liquidity. OpenCSD provides for the possibility of cross border, multicurrency, settlement operating round the clock.


Private Equity

A bank facilitates both issuers and investors in private equity. As part of that service it maintains a register of investors for each company. OpenCSD provides a fully functional settlement destination which allows for changes in security ownership. It maintains a 'golden record' of transactions and balances and a full history of the company from its inception.


Commercial Invoices

Factoring and discounting of invoices for commercial entities forms an important part of the liquidity environment - particularly for smaller companies. An organised settlement location would allow for a more efficient, less risky and more liquid market to emerge.

OpenCSD is designed to support any kind of arrangement that requires an ownership register and a means of changing that register.

Financial Services Ready

OpenCSD is designed to work within regulated financial environments.


OpenCSD maintains a complete and cryptographically provable record of transactions and balances


Blockchain technology provides for both data and functionality to be distributed for resilience and security.


OpenCSD works with industry standard Global Legal Entity Identifiers and ISO standard messaging.


SETL employs the latest cryptographic techniques in both its blockchain implementations and its messaging and membership structure.

Billions of Transactions

SETL's highly optimised blockchain engine is capable of processing billions of transactions per day across nodes in multiple locations. Capacity is effectively unbounded as SETL's interoperating ledger architecture can distribute the load of transaction processing across co-operating distributed chains.

Interoperable Ledgers

Assets recorded on one ledger can be transferred to another SETL subject to the permissions of the ledger operators. This allows co-operative but private configurations to be maintained - such as a sub-registry held by a custodian against a nominee holding at a CSD.
