Kinexys as the settlement layer

The disclosure names the bank, the platform, and a launch window. The service is designed for corporate clients. No throughput targets or pilot parameters appeared in the Yonhap account.

Cross-border blockchain payment services have reached market with comparable disclosure before. Transaction volume, once the service goes live, is the number that will show whether the Kinexys channel generates real corporate flow. The planned launch is next month, Yonhap said.
