The problem
Korea’s retail crypto frenzy ran ahead of its market structure: thin local order books, fragile smaller exchanges, and no trusted default venue where millions of first-time traders could buy and sell safely in won.
How it works
Dunamu launched Upbit in October 2017 with deep KRW pairs and a fast mobile app, then layered custody, wallets and blockchain infrastructure (including the Giwa chain) around the exchange. It secured Korea’s first virtual-asset service provider qualification in 2021, cementing its regulated-leader status.
Pain points
Illiquid pre-2017 domestic venues, hacks and freezes at smaller exchanges, and retail users navigating unclear compliance and tax treatment on their own.
Business model
Transaction fees on spot trading volume, with custody, infrastructure and partner services on top — a model that prints money in bull markets and compresses hard in downturns.
Challenges
Extreme dependence on trading-fee cycles, ever-tightening Korean exchange regulation and listing scrutiny, plus execution risk on the giant Naver merger —including keeping liquidity and users from drifting to Bithumb during integration.
Funding

Latest — May 2026
Hana Bank agreed to buy a 6.55% stake in Dunamu for about 1 trillion won (~$670M), becoming its fourth-largest shareholder, with joint plans around won-pegged stablecoins and blockchain-based finance — a bank-validation signal six months after Naver Financial’s $10.3B all-stock acquisition agreement, one of Asia’s largest fintech deals of 2025.
