KB Kookmin, the largest bank in South Korea, plans to roll out a cross-border payment service for corporate clients that leverages JPMorgan's Kinexys blockchain network in August. This marks a significant milestone as it will be the first instance of a South Korean bank utilizing Kinexys for international trade transactions. The service will be accessible through the bank's branches in South Korea and Singapore, initially focusing on dollar transactions across ten nations, including the United States, India, Saudi Arabia, and the UAE.
