Kyobo Life Insurance and Japan’s SBI Group have completed a cross-border proof-of-concept testing a direct yen-to-won stablecoin-based institutional settlement structure on Canton Network without routing the transaction through the U.S. dollar. The pilot covered transfer, foreign exchange, settlement and transaction tracking, but it used test tokens in a test environment rather than real institutional funds or live stablecoins.
The project, conducted with SBI Digital Practice, tested whether blockchain infrastructure could simplify institutional transfers between Japan and South Korea by directly converting a yen-denominated stablecoin representation into a won-denominated equivalent. The companies also examined real-time transaction tracking and an operating model for handling transferred digital assets and related settlement funds in South Korea.
Key Findings
- Kyobo Life and SBI Group completed a Japan–South Korea stablecoin-based cross-border proof-of-concept that began in July 2026.
- The pilot was conducted with SBI Digital Practice using Canton Network’s test environment.
- The companies tested direct conversion between yen- and won-denominated stablecoin representations without first routing the transaction through the U.S. dollar.
- The proof-of-concept covered institutional transfer, foreign exchange, settlement and real-time transaction tracking.
- Test tokens were used rather than real institutional funds or live stablecoins, and no commercial launch date has been announced.
What Happened?
Kyobo Life said on September 17 that it had completed a Korea–Japan stablecoin-based cross-border proof-of-concept with Japan’s SBI Group after beginning the project in July.
The test was conducted with SBI Digital Practice, an SBI Group company, using Canton Network’s test environment. According to Kyobo Life, the project examined the full process of transferring, converting and settling institutional value across the two countries.
The central test involved directly converting a yen-denominated stablecoin representation into a won-denominated stablecoin representation rather than first converting yen into U.S. dollars and then dollars into won.
The companies used test tokens to model the process. That distinction is critical: the project demonstrated a technical and operational structure, but it was not a live transfer of institutional money and should not be described as the commercial launch of a Japan–South Korea stablecoin settlement corridor.
How the Yen-to-Won Structure Was Tested
The proof-of-concept focused on a transaction path from Japan to South Korea and examined whether a more direct currency-conversion structure could be created using tokenized representations of yen and won.
In a structure that uses the dollar as an intermediary, yen can first be converted into U.S. dollars before the dollar position is converted into Korean won. That creates an additional foreign-exchange step between the two local currencies.
Seoul Economic Daily reported that the proof-of-concept instead used test tokens to verify a structure in which a yen-denominated stablecoin could be converted directly into a won-denominated stablecoin without routing through the dollar.
Kyobo Life said the test indicated the potential to shorten processing times and reduce costs by simplifying intermediary foreign-exchange procedures. Those are findings from a proof-of-concept, however, rather than measured savings from a commercial production system.
The Pilot Covered More Than a Token Transfer
The project was broader than sending a test token between two blockchain addresses.
Kyobo Life and SBI examined the institutional workflow around the transaction, including fund transfer, currency conversion and settlement. They also tested whether transaction information could be viewed and tracked in real time using blockchain infrastructure.
The companies additionally examined an operating model for handling digital assets transferred from overseas and their related settlement funds within South Korea.
This broader scope matters for institutional finance because transferring a digital token is only one component of a cross-border transaction. Institutions also need operational processes around foreign exchange, settlement, reconciliation, transaction records and control of the assets involved.
Why Canton Network Was Used
The proof-of-concept used the test environment of Canton Network, blockchain infrastructure designed around financial-institution use cases.
Electronic Times reported that the project was conducted jointly with SBI Digital Practice and used Canton Network’s test environment to verify the cross-border institutional transfer, conversion and settlement structure.
For this project, Canton provided the blockchain environment in which the companies could model the movement and conversion of tokenized value while examining the surrounding institutional workflow.
The test adds another institutional use case for blockchain-based financial infrastructure. However, the use of Canton’s test environment should not be interpreted as evidence that a production Korea–Japan stablecoin settlement corridor is currently operating on the network.
Why Bypassing the Dollar Matters
The most distinctive part of the pilot is the direct yen-to-won structure.
When a cross-border transaction uses an intermediary currency, additional conversion steps can add operational complexity, processing time and exposure to costs associated with those conversions.
The Kyobo–SBI proof-of-concept tested whether tokenized representations of the two local currencies could create a more direct route between them.
Newsis reported that the companies tested direct exchange between yen- and won-denominated stablecoin representations and also examined real-time transaction tracking and the domestic handling of transferred digital assets and related settlement funds.
This does not establish that blockchain settlement is automatically cheaper or faster than existing financial infrastructure. It shows that the companies tested a structure designed to remove an intermediary dollar-conversion step and identified potential efficiency benefits for further evaluation.
This Was Not a Live Stablecoin Payment
The distinction between a proof-of-concept and a production financial service is central to the announcement.
The yen- and won-denominated tokens were used to represent the proposed stablecoin structure inside a test environment. The proof-of-concept should therefore not be presented as evidence that live commercial yen and won stablecoins moved between Kyobo Life and SBI Group.
There is also no announced customer-facing service, production transaction volume or commercial launch date associated with the September 17 result.
The result demonstrates that the companies completed the planned technical and operational test. Whether the model can progress into real-value institutional settlement is a separate question that would require another stage of development.
What Would Be Needed for Commercial Deployment
Moving from test tokens to live institutional settlement would require more than the transaction path demonstrated in the proof-of-concept.
A production system would need to operate within the applicable regulatory and financial frameworks in Japan and South Korea, while the relevant stablecoin, foreign-exchange and settlement infrastructure would need to support real transactions.
Operational questions would also need to be resolved around issuance and redemption, liquidity, custody, compliance, transaction limits and the legal treatment of the assets and settlement process.
Kyobo Life has indicated that the potential usefulness of the tested structure depends on the development of the relevant regulatory framework and financial infrastructure. The companies have not provided a timetable for a commercial transition.
Kyobo Life and SBI Plan Further Web3 Cooperation
The proof-of-concept is not expected to be the end of the companies’ work together.
Financial News reported that Kyobo Life and SBI Group plan to expand their Web3 financial cooperation, including work related to digital-asset foreign exchange between South Korea and Japan, links with asset management and exploration of new business models.
Those areas remain prospective. The companies have not announced a production service, commercial product specifications or a launch schedule for a live Korea–Japan stablecoin settlement system.
A future move involving real-value transactions would therefore represent a materially different stage from the proof-of-concept announced on September 17.
Why It Matters
The significance of the Kyobo–SBI pilot lies less in transaction size than in the institutional workflow it attempted to reproduce.
A major South Korean insurer and a Japanese financial group tested how tokenized currency representations could be incorporated into cross-border transfer, foreign exchange, settlement and transaction tracking without relying on the U.S. dollar as an intermediary currency.
That makes the project relevant to the broader development of blockchain-based financial infrastructure in Asia, particularly as financial institutions examine how tokenized money could interact with existing cross-border payment and settlement processes.
At the same time, the proof-of-concept does not establish commercial viability, regulatory readiness or superiority over existing payment infrastructure. Those questions would require a production deployment and measurable transaction data.
What to Watch Next
- Whether Kyobo Life and SBI progress from test tokens to a production pilot involving real institutional value.
- Regulatory and infrastructure developments in Japan and South Korea that could support yen- and won-denominated tokenized settlement.
- Whether the companies identify issuers or infrastructure providers for any future live currency-backed tokens.
- Whether a future deployment provides measurable data on settlement time, foreign-exchange costs and transaction volumes.
- Further integration between the tested settlement model, digital-asset foreign exchange and institutional asset management.
The Bottom Line
Kyobo Life and SBI Group have completed a proof-of-concept testing a direct yen-to-won tokenized settlement structure on Canton Network without using the U.S. dollar as an intermediary currency.
The project is notable because it examined the broader institutional process around cross-border transfer, foreign exchange, settlement and transaction tracking rather than a token transfer in isolation.
But the boundary is equally important: this was a test-environment proof-of-concept using test tokens, not the launch of a live stablecoin payment corridor. A move into real-value institutional settlement would represent the next materially different stage of the project.
