Toss and KOMSCO Join Forces to Build Blockchain Payment Infrastructure

On April 23, 2026, Toss (Viva Republica), a leading domestic fintech company, and the Korea Minting and Security Printing Corporation (KOMSCO) announced that they have signed a strategic memorandum of understanding (MOU) to build a next-generation payment infrastructure based on blockchain. This collaboration was initiated to proactively respond to changes in the digital financial environment by combining Toss's vast user base of 30 million with KOMSCO's public payment network.

This agreement will serve as an opportunity to advance payment infrastructure while simultaneously verifying the potential of new payment methods.

The MOU signing ceremony took place on April 22, 2026, at the Toss Sinnonhyeon office in Seocho-gu, Seoul. Key executives from both companies, including Toss CEO Lee Seung-gun and KOMSCO President Sung Chang-hoon, attended the event to discuss plans for introducing payment systems utilizing blockchain technology and the future cooperation roadmap.

Synergy Between Private Fintech and Public Infrastructure

As of July 2025, Toss has secured 30 million cumulative subscribers, leading the private financial services market with services such as simple transfers and credit inquiries. On the other hand, KOMSCO manages key public sector infrastructure, operating 'chak,' a public payment platform for local currencies in 83 local governments nationwide and digital Onnuri gift certificates, with over 2 million users.

• Enhancing user accessibility and payment convenience by linking local government currencies with the Toss app
• Advancing payment infrastructure for digital Onnuri gift certificates and expanding usage through private apps
• Strengthening the security of payment systems and managing transparent fund flows using blockchain technology

In the mid-to-long term, the two companies agreed to jointly promote pilot projects using token-based payment methods such as deposit tokens and stablecoins. Through this, they plan to verify technical applicability in real payment environments and establish a foundation for providing customized payment services optimized for individual consumption patterns.

This collaboration goes beyond simple system linkage to discover next-generation payment models and build a shared infrastructure. In particular, the full-scale introduction of blockchain technology into public services is expected to increase the efficiency of payment processes, prevent security incidents, and contribute to building social trust in digital finance.

Strategic Asset Comparison and Market Outlook

The collaboration between the two companies is drawing market attention as a combination of their respective core assets. The meeting of Toss's innovative financial interface technology and KOMSCO's public infrastructure operation know-how is expected to present a new standard for the digital payment market, which will become clearer through detailed comparative indicators to be released in the future.

Market experts evaluate this partnership as one of the most influential collaboration models between the domestic fintech industry and a public institution. Analysis suggests it could act as a catalyst to accelerate the full-scale introduction of digital assets like stablecoins into everyday payments.

Key points to watch moving forward are the specific results and user acceptance of the pilot projects utilizing deposit tokens and stablecoins. If these technical attempts successfully take root in actual retail payment settings, the expansion of blockchain-based payment infrastructure in Korea is expected to accelerate further.
