Blockchain-based payments and settlement infrastructure company Suho IO unveiled a next-generation foreign exchange (FX) settlement model using stablecoins.

Suho IO on Feb. 4 hosted the Seoul Digital Money Summit 2026, or SDMS 2026, for financial leaders at the Conrad Seoul in Yeouido.

SDMS is an annual event hosted by Suho IO for global financial leaders. It continues discussions on institutional digital asset trading infrastructure, including stablecoins, central bank digital currencies (CBDCs) and deposit tokens.

This year's event, held under the theme "Korean stablecoin infrastructure innovation that financial leaders need to know," looked at policies, technology, pilot cases and how systems work, going beyond sharing trends centered on Korea's stablecoin market. About 150 people attended, including officials from domestic and foreign traditional financial institutions and digital asset companies. Suho IO also debuted a new project related to its next-generation stablecoin-based FX settlement infrastructure.

Shin Seung-hwan (신승환), a partner at Boston Consulting Group (BCG) who joined as a speaker, said stablecoins are rapidly spreading as payments and settlement infrastructure alongside rapid growth in the global digital asset market. He also said Korea has differentiated opportunities in cross-border remittances and digital asset finance, given its advanced existing payments infrastructure.

Park Ji-su (박지수), CEO of Suho IO, delivered a presentation and shared results from Project Namsan, a domestic stablecoin pilot. Based on a pilot involving about 2,000 foreign tourists from September last year to the present, he said it confirmed about a 70 percent reduction effect, including lowering retail FX exchange fees from about 1 percent to an average of about 0.3 percent. He also said merchants were able to settle instantly without additional fees, improving operational efficiency.

He then unveiled Ezys, a next-generation stablecoin-based FX settlement infrastructure, and conducted a live demonstration. Ezys is an FX settlement infrastructure that applies an auction-style matching method that automatically executes trades on the most favorable terms by comparing real-time quotes from multiple financial institutions after users enter desired exchange and remittance conditions. It is currently used in various fintech services under Project Namsan.

The on-site demonstration showed a process in which a dollar stablecoin is automatically matched in real time with an institution offering the best exchange-rate terms and settled immediately through TikoPay, a stablecoin-based payment app for foreign tourists. TikoPay was used in the Project Namsan pilot, and payment transactions generated in the app are processed through Ezys' settlement engine. Suho IO plans to expand the TikoPay payment service to about 200 merchants at major hubs including Gangnam, Seongsu and Euljiro within this month.

Park said the summit addressed stablecoins from multiple perspectives such as pilots and infrastructure rather than stopping at concepts or outlooks. He said he aims to present the possibility that stablecoins can be used in Korea's financial infrastructure through Ezys, an FX settlement infrastructure being introduced domestically for the first time.
