Toss Parent Viva Republica Building Proprietary L1 Blockchain

South Korean fintech leader Viva Republica, the operator of the popular financial super-app Toss, is expanding its digital infrastructure by building a proprietary layer one (L1) blockchain mainnet. According to a report published by Blockmedia on April 6, 2026, the company is developing both the blockchain and a native cryptocurrency to integrate directly into its existing suite of payment, banking, and securities services.

In addition to the mainnet development, the company has signaled its intent to bolster its digital asset capabilities by filing 24 trademarks related to stablecoins. These filings suggest that Viva Republica is positioning itself to play a central role in the regional Web3 ecosystem, aiming to bridge traditional financial services with decentralized ledger technology. By internalizing its blockchain infrastructure, Toss intends to streamline its cross-service operations and provide a more cohesive digital asset experience for its user base. The initiative represents a significant shift for the company as it seeks to leverage blockchain technology to enhance its platform's functionality across its diverse financial product offerings.
