Two of Ripple's key partners in Asia have completed a proof-of-concept that could reshape how institutional money moves between Japan and South Korea, without touching the U.S. dollar.
SBI Group and Kyobo Life Insurance completed the Japan-South Korea stablecoin-based cross-border proof-of-concept project, performing a direct transfer between Japanese yen (JPY) and Korean won (KRW) stablecoins without relying on the U.S. dollar as an intermediary currency.The test ran on the Canton Network (@CantonNetwork) test environment starting in July 2026.
The test has drawn attention in Ripple circles because both firms have ties to Ripple, although Ripple's technology was not part of this specific pilot.
The pilot modeled a transaction path where a yen-denominated stablecoin could be swapped directly for its won-denominated counterpart, cutting out the usual intermediate step of converting yen into dollars and then dollars into won.The Canton Network test environment handled institutional transfer, foreign exchange, settlement, tracking, and reconciliation processes.
It is important to note the scope of what was demonstrated. Only test tokens were used; no real stablecoins or institutional funds changed hands during the exercise.Kyobo Life said the results demonstrated the "technical feasibility and efficiency" of stablecoin-based institutional transfers, arguing that fewer currency-conversion steps could shorten processing time and lower transaction costs. The company did not publish any figures quantifying those savings, so the efficiency claim remains qualitative for now.
The entire exchange ran on Canton Network, a blockchain built specifically for regulated financial institutions that need configurable privacy and permission controls when moving assets and settlement data. That design matters because insurers and banks generally cannot operate on fully public blockchains where transaction details are visible to anyone.
Kyobo Life called the project South Korea's first cross-border institutional stablecoin test by an insurer, though that characterization comes from Kyobo Life and has not been presented as a finding by a regulator.
Both parties stated that the model is expected to reduce time, costs, and exchange rate risks in cross-border institutional fund transfers. The project also proved an operational model for safely handling digital assets transferred from overseas and their associated settlement funds domestically. SBI and Kyobo Life plan to further cooperate in the Web3 ecosystem, including Japan-South Korea digital asset exchanges, asset management, and new business models based on transaction structures.
SBI is separately building Project Musubi, a Japan-Korea stablecoin payment network with Korean firm Nodeinfra, distinct from the Kyobo Life pilot. The two efforts point toward the same destination: a working stablecoin corridor between Japan and South Korea, but they remain separate tracks moving at their own pace.
