Digital Asset Expansion Drives Strategy
The Samsung companies said the investment aims to strengthen business cooperation.
They also said the digital asset market is creating new revenue opportunities. This includes areas linked to stablecoins and tokenized securities.
The companies identified a won-denominated stablecoin as one possible growth area. Stablecoins are digital tokens that track the value of a fiat currency. A won stablecoin would track South Korea’s national currency. Samsung Securities plans to work with Dunamu on virtual asset services.
The company also named security token offerings as a focus area. Security tokens are digital tokens linked to regulated financial assets.
