Samsung SDS Wins Korea Securities Depository Contract to Build Token Securities Platform

Samsung SDS said Wednesday it had won a contract from the Korea Securities Depository to build and operate a token securities, or STO, platform.

STOs are digital securities issued and managed on blockchain-based systems that allow assets to be recorded and traded electronically. Demand for tokenizing real-world assets has been rising, boosting expectations for market expansion. In response, the Korea Securities Depository has been strengthening STO issuance and management functions by linking its electronic securities account system with distributed ledger data.

Samsung SDS has built relevant capabilities through earlier projects, including STO functional analysis consulting in 2024 and the construction of a test-bed platform in 2025. Under the latest contract, the company plans to build a full-scale STO system by February 2027 that can process live transactions and support stable service operations.

The system will include a total volume management platform to track STO issuance and distribution in real time, with the aim of improving transaction transparency. Samsung SDS will also build broader IT infrastructure, including a gateway system, an operating and management framework for blockchain nodes, and a distributed ledger system.

Lee Jung-heon, vice president of Samsung SDS's Strategic Marketing Office, said the project would support the growth of the STO market and help create a flagship case in digital assets.

Separately, Samsung SDS earlier this year created a Digital Asset Consulting Group under the Financial Consulting Team in its Strategic Marketing Office. The unit is responsible for business strategy and sales related to digital assets such as STOs and stablecoins.
