South Korea's financial technology powerhouse Toss is making bold moves into Web3 territory with plans to develop its own blockchain mainnet and cryptocurrency ecosystem. According to Bitcoin News, the company which serves 30 million users (nearly 60% of South Korea's population) has established a dedicated Stablecoin Task Force led by Chief Business Officer Kyuha Kim. The initiative includes developing a proprietary layer one blockchain and native digital currency to integrate across its existing payment, banking, and securities platforms. Toss has been actively recruiting blockchain engineers since February 2026, posting roles covering everything from wallet systems to cryptographic signing and regulatory compliance. The company filed trademarks for 24 Korean won stablecoin names in June 2025, including "TOSSKRW," signaling serious intent to launch localized digital currency solutions. With consolidated revenue of approximately $1.4 billion in 2024 and plans for a U.S. IPO targeting a $10 billion valuation, Toss's Web3 expansion represents one of the most significant mainstream financial institutions entering the blockchain space this year.
