South Korea's financial super-app Toss is making significant strides into Web3 territory by developing its own Layer 1 blockchain mainnet and native cryptocurrency, as reported by Blockmedia. The company, which serves approximately 30 million users representing nearly 60% of South Korea's population, has been strategically positioning itself for the decentralized economy by filing 24 Korean won stablecoin trademarks in June 2025, including "TOSSKRW." According to Bitcoin News, the fintech powerhouse has been actively recruiting blockchain engineers since February 2026, focusing on critical areas like wallet systems, cryptographic signing, and financial compliance. The ambitious initiative includes developing an integrated Web3 wallet directly within Toss's existing app ecosystem, eliminating the need for separate downloads while supporting virtual asset storage, transfers, and tokenized securities management. This comprehensive approach signals Toss's commitment to bridging traditional finance with Web3 infrastructure as they target a U.S. IPO valuation above $10 billion in 2026.
