South Korea's leading fintech platform Toss is positioning itself at the forefront of Web3 adoption with ambitious blockchain infrastructure plans that could reshape digital finance for its 30 million users. According to Bitcoin.com, the company is developing a proprietary Layer 1 blockchain mainnet and native cryptocurrency to integrate across its comprehensive financial ecosystem spanning banking, payments, and securities trading.
The strategic initiative includes 24 Korean won-pegged stablecoin trademarks filed in June 2025, including the flagship "TOSSKRW" brand, signaling serious intent to bridge traditional finance with decentralized protocols. With regulatory clarity still pending under South Korea's Digital Asset Basic Law, Toss faces a crucial architectural decision between Layer 1 and Layer 2 approaches. The company's aggressive hiring of blockchain engineers since February 2026 and plans for an integrated Web3 wallet within its existing super app demonstrate how established fintech players are preparing for the convergence of traditional and decentralized finance.
