OKX Ventures has taken a ~20% stake in Coinone, one of South Korea's largest crypto exchanges, becoming a joint third-largest shareholder alongside Korea Investment & Securities — each now holds 19.6%.

The stake is part of a 160B KRW (~$106M) package of new and existing shares. Founder & CEO Cha Myung-hoon stays the top individual shareholder at 27.8% with full management control; Com2uS Holdings & affiliates hold 25%.

Beyond capital it's a technology deal: Coinone will integrate OKX's matching engine, custody system and wallet technology to sharpen trading infrastructure, compliance and institutional services. OKX CEO Star Xu noted Cha's white-hat security background fits OKX's engineering-first culture.
