KB Financial Group, the parent company of South Korea’s largest bank KB Kookmin, has concluded a pilot program for a stablecoin denominated in South Korean won. The project tested the stablecoin’s full lifecycle — from issuance and merchant settlement to international remittance — leveraging the Kaia blockchain platform alongside partners KG Inicis and OpenAsset.
The pilot showcased a notable reduction in remittance costs and transaction time. In one case, the won stablecoin was converted into a US dollar stablecoin and transferred to a bank account in Vietnam within three minutes. This transfer lowered fees by approximately 87% compared to the traditional SWIFT network, the global messaging system used by banks for international payments.
Offline payments were also trialed at a Seoul-based coffee chain, Hollys, where customers used QR codes to pay with the won stablecoin without installing any cryptocurrency wallets. This approach underlines the potential for user-friendly, blockchain-based payments integrated into everyday commerce.
South Korea’s leading financial institutions are increasingly engaging with stablecoins as the technology gains traction. Notably, Shinhan Card recently partnered with the Solana Foundation to explore similar stablecoin payment solutions, reflecting a growing regional trend toward digital currency experimentation within established financial channels.
KB Financial plans to formally launch stablecoin services once the country enacts clear digital asset regulations. However, progress is stalled amid regulatory disagreements over stablecoin issuance authority. The Bank of Korea favors granting issuance control primarily to banks, whereas the Financial Services Commission cautions that stringent rules could hinder fintech innovation. Discussions on the country’s Digital Asset Basic Act are not expected to advance until after upcoming local elections.
This pilot positions KB Financial at the forefront of South Korea’s transition toward integrating blockchain technology into conventional finance, highlighting both the efficiencies stablecoins can bring to cross-border transactions and the challenges posed by regulatory uncertainties.
