OpenCSD Blockchain Payment Settlement Technology? promises to offer simple, unified, and immediate blockchain settlements and payments. Find out how it works today in our review.

What is

SETL is a London-based institutional payment and settlement infrastructure based on blockchain technology.

The company was launched in July 2015 with the goal of creating a multi-asset, multi-currency institutional payment and settlements infrastructure on the blockchain. Using SETL, market participants can move cash and assets directly between each other, leading to the immediate and final settlement of market transactions.

SETL’s system maintains a permissioned, distributed ledger of owners and transaction records, simplifying the process of matching, settlement, custody, registration, and transaction reporting.

Today, SETL is capable of processing approximately 1.4 billion transactions per day. That platform is available to clients in the form of SETL OpenCSD, which allows market participants to run permissioned registry services for payments, settlement, and clearing of cash and other financial instruments.

How Does SETL Work?

SETL is the blockchain, and SETL OpenCSD is the customer-facing solution. SETL’s blockchain is at the heart of OpenCSD.

That blockchain is capable of processing billions of transactions per day. The highly optimized engine processes these transactions 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.

SETL also emphasizes interoperable ledgers, allowing the platform to sync with existing solutions. Assets recorded on one ledger can be transferred to another SETL subject to the permissions of the ledger operators. This means co-operative and private configurations can be maintained – like a sub-registry held by a custodian against a nominee holding a CSD.

SETL Features

SETL’s OpenCSD emphasizes all of the following features:


SETL OpenCSD provides users with the tools they need to maintain a membership. This, in turn, allows for the interaction between owners and issuers, with identity and permissioning built in.

Every aspect of SETL is designed to be customizable. Users can use the API to build their own apps that extend the functions of the SETL platform.

Use Cases for SETL

Our description of SETL has been fairly technical so far. Obviously, it helps to learn where SETL OpenCSD can be used. The platform can be customized and adapted to a range of financial industries:

Mutual Funds:

SETL can be used for mutual funds. The OpenCSD platform can standardize and streamline ownership, issue, and redemption records.

Private Equity:

OpenCSD provides a fully functional settlement destination allowing for changes in security ownership, helping to maintain a “golden record” of transactions and balances and a full history of the company from its inception.

Cross Border:

SETL facilitates cross-border, multi-currency settlement operations around the clock, opening the door to cross-border finance.

Commercial Invoices:

Organized settlement locations allow for a smoother, less risky commercial invoicing process.

Financial Services:

SETL OpenCSD can be adapted to work with all types of financial services. The platform is specifically designed to work within regulated financial environments. That means users enjoy compliance, resilience, standards, and security when running SETL OpenCSD. Compliance is achieved through a complete and cryptographically provable records of transactions and balances. Meanwhile, SETL’s standards include industry standards like Global Legal Entity Identifiers and ISO standard messaging.
