Japan's SBI Digital Practice and South Korea's Kyobo Life have completed a proof of concept for converting a yen-denominated stablecoin representation directly into a won-denominated one without first routing the transaction through the U.S. dollar.
The project began in July and ran in Canton Network's test environment, according to Kyobo's Sept. 17 announcement. The companies used test tokens to model the transfer, foreign-exchange and settlement steps for institutional funds moving from Japan to South Korea.
A dry run, not a live payment rail
The distinction between a proof of concept and a live transfer matters. Crypto.news reports that no actual institutional money or production stablecoins moved during the demonstration.
Kyobo said the test also examined real-time transaction tracking and how digital assets arriving from overseas, along with their associated settlement funds, could be handled inside South Korea. The insurer argues that removing the intermediate dollar conversion could shorten processing and lower foreign-exchange costs. It did not publish comparative figures measuring those savings.
The companies are still exploring what comes next
Kyobo and SBI said they plan to explore more cooperation involving digital-asset exchange, asset management and transaction-based business models between Japan and South Korea. They did not give a date for a production service.
That leaves the project as a technical and operational demonstration rather than a new cross-border payment product. It shows how a direct yen-to-won route could be structured on Canton, while live deployment still depends on regulated assets, supporting financial infrastructure and further commercial work.
