Toss Considers Launching Native Cryptocurrency and Custom Blockchain

South Korean fintech giant Toss, operated by Viva Republica with 30 million registered users and $1.8 billion in 2025 revenue, is considering launching its own Layer 1 or Layer 2 blockchain and native cryptocurrency to support its stablecoin strategy. Corporate development director Seo Chang-whoon frames the move as essential infrastructure for a Money 3.0 era, aiming to complete a borderless financial super app by 2026. The decision is being shaped by South Korea's pending Basic Law on Digital Assets, which will codify strict stablecoin requirements including 100% reserve backing and may favor bank-led consortia. Industry observers see the second half of 2025 through first half of 2026 as an explosive growth window for Korean stablecoins, making Toss's blockchain architecture choice strategically critical for its next phase of expansion.
