KB Financial Group, the parent company of South Korea’s largest bank, KB Kookmin, announced the successful completion of a technical proof-of-concept for a won-denominated stablecoin. Executed on the Kaia blockchain, the pilot managed end-to-end issuance, offline retail payments, and international remittances.
Collaborating with payment processor KG Inicis and fintech firm OpenAsset, KB Financial tested real-world cross-border utility. During the pilot, the won-backed stablecoin was converted into a digital dollar asset via Kaia’s on-chain liquidity before being delivered directly to a fiat bank account in Vietnam.
The entire cross-border transaction took less than three minutes. According to a Kaia spokesperson, this blockchain-driven approach achieved an 87% fee reduction compared to the traditional SWIFT banking network, which typically requires several days to clear.
For the everyday retail trial, KB integrated the technology into kiosks at the popular Seoul-based coffee chain Hollys. Customers made purchases simply by scanning a QR code at checkout. A key breakthrough of the demonstration was that users could automatically trigger blockchain smart contracts without needing to install or manage a dedicated cryptocurrency wallet.
With over $266 billion in assets, KB Financial is preparing for a full commercial rollout once South Korea’s pending Digital Asset Basic Act establishes an official framework. However, the legislation remains stalled over regulatory disputes regarding whether banks or fintech firms should hold majority ownership over stablecoin issuance. Deliberations are unlikely to resume before the nation’s upcoming June local elections.
