Samsung SDS builds stablecoin infrastructure with Dunamu before Korean law, after $408 million stake. Bank of Korea wants bank-led consortia. Fintech groups resist.
Samsung SDS is in talks with Dunamu, the company behind the Upbit exchange, to build stablecoin infrastructure and tokenized securities systems, chief executive Lee Jun-hee said during the company's second-quarter earnings call on July 30. The companies also plan AI-based payment tools, Lee said.
Neither company can issue a won-pegged stablecoin today. South Korea does not have a stablecoin law. The Financial Services Commission said July 29 it is merging 10 pending crypto and stablecoin bills into a single Digital Asset Basic Act. It has not set a filing date. The central unresolved question is who can issue. The Bank of Korea wants a bank-led consortium holding at least 51% ownership. The FSC and fintech groups have opposed that.
Samsung isn't alone in this bet. Samsung SDS bought a stake in Dunamu jointly with Samsung Securities and Samsung Card in May for about $408 million. Hana Bank invested $670 million in the same company earlier. Mirae Asset took control of rival exchange Korbit and rebranded it Digital X. OKX Ventures and Korea Investment & Securities bought into Coinone. None of these deals wait for the law. All of them lock in exchange stakes or infrastructure access before licensing terms exist.
Samsung SDS frames the Dunamu stake as strategic rather than financial, Lee said. The two companies plan to combine Dunamu's blockchain operating experience with Samsung SDS's IT services, AI, cloud, and security stack. Lee said Samsung SDS already has relevant groundwork from a tokenized-securities platform built with the Korea Securities Depository and end-to-end testing of stablecoin issuance-to-settlement. Samsung SDS's earnings presentation called the May investment part of a "full-scale digital asset business collaboration."
Samsung SDS did not respond to a request for further detail. Dunamu declined to comment.
Samsung SDS's Q2 2026 revenue reached 3.72 trillion won, about $2.68 billion. That was up 5.9% from a year earlier, per the company's earnings release. Operating profit rose 0.7% to 232 billion won. Cloud revenue, the segment most relevant to any Dunamu buildout, climbed 17% to 779 billion won.
Until Korea decides who can issue a won stablecoin, Samsung SDS and Dunamu are building toward a product with no confirmed legal path to market. The FSC wants its unified bill finished sometime in 2026. The same bank-versus-fintech dispute that has stalled the legislation twice remains unresolved.
