KB Financial Group completed a pilot programme testing stablecoin-powered offline payments and cross-border remittances through the Kaia blockchain ahead of South Korea’s proposed digital asset framework.

A Kaia spokesperson told Cointelegraph the pilot enabled a won stablecoin to be converted into a US dollar stablecoin and transferred to a bank account in Vietnam in under three minutes with an 87% reduction in fees compared with the SWIFT network.

The experiment also included offline QR code payments at Seoul-based coffee chain Hollys, allowing users to make purchases without installing a cryptocurrency wallet.
