KakaoBank is developing blockchain infrastructure for a won‑pegged stablecoin called "Kakao Coin," recruiting backend developers with smart‑contract and token‑standards expertise and key management capabilities. The bank is partnering with Korea Investment & Securities and Lucent Block to build security token offering (STO) products and systems. These moves follow amendments to South Korea’s Electronic Securities Act and Capital Markets Act that enable an STO market from H1 2026; the industry has estimated the STO market could be worth up to $287 billion by 2030. Kakao Group has formed a stablecoin task force while rivals Naver and Dunamu advance their own stablecoin and wallet initiatives.
