Samsung SDS is evaluating stablecoin infrastructure and other digital-payment business models with Dunamu, the operator of South Korean cryptocurrency exchange Upbit, as the Samsung IT-services company seeks to expand its digital-asset infrastructure work.
The initiative is exploratory rather than a product launch. Samsung SDS has not announced a stablecoin, commercial payment service, implementation partner roster or deployment timetable. It has also not specified which company would perform any regulated issuing, custody, exchange or settlement role.
Samsung SDS chief executive Junehee Lee described the direction during the company’s second-quarter earnings call on July 30. In its official English call script, the company said Samsung SDS, Samsung Securities and Samsung Card together acquired a 4% stake in Dunamu in May and characterized the investment as strategic.
The partnership starts with infrastructure capabilities
Samsung SDS said it intends to combine its IT services, cloud and security capabilities with Dunamu’s blockchain expertise. The company also said it has worked on the Korea Securities Depository’s tokenized-securities platform and completed end-to-end validation of a stablecoin process, from issuance through settlement, with domestic financial institutions.
Those statements establish technical work and corporate intent, but not a live service. The call script does not identify the financial institutions involved in the validation, the token or blockchain used, transaction values, measured performance or whether real customer funds moved. The validation should therefore be understood as company-described infrastructure testing rather than evidence of commercial payment volume.
Yonhap News Agency reported from the earnings call that Lee identified stablecoin infrastructure, financial systems integration for virtual assets and AI-based next-generation payments among the opportunities under consideration. He said the companies plan to discuss cooperation and make potential business models more concrete.
For payment providers, that language leaves the eventual position in the value chain open. Samsung SDS could supply systems integration, cloud hosting, security controls or transaction-processing components without becoming a token issuer or consumer-facing wallet operator. Dunamu could contribute blockchain and exchange infrastructure, but the companies have not assigned responsibilities publicly.
Issuance-to-settlement testing is only a starting point
An end-to-end stablecoin process must coordinate more than token transfers. A commercial system would need rules for reserve funding and redemption, customer and transaction screening, wallet or account controls, liquidity management, reconciliation with bank money and procedures for failed or disputed transactions.
Merchant use would add another operational layer. Payment acceptance requires pricing, conversion, refunds, settlement timing and a clear description of what the merchant ultimately receives. None of those design choices is disclosed in the earnings materials.
The collaboration is distinct from Samsung Electronics’ separate plan to add native stablecoin support to Samsung Wallet. The wallet announcement concerns a potential consumer interface, while Samsung SDS is discussing enterprise digital-finance infrastructure with Dunamu. The companies have not said that the two initiatives will be connected.
Regulatory design will shape any rollout
South Korea is still developing a broader framework for stablecoin issuance and circulation. That makes regulated-role allocation a central question for any future service. Technology providers can build issuance and settlement systems, but a commercial model also needs legally accountable entities for reserves, redemption, safeguarding and compliance.
The strategic investment gives Samsung SDS and Dunamu a basis to develop those options together. For now, however, the supported conclusion is limited: Samsung SDS has identified stablecoin and AI-based payment infrastructure as potential business areas and plans to refine cooperation with Dunamu. It has not announced an issued asset, completed integration, active payment corridor or merchant rollout.
