Korea's biggest bank just ran a won stablecoin end-to-end
KB Financial Group, parent of KB Kookmin, completed a proof of concept covering the full lifecycle of a won-denominated stablecoin, from issuance through offline payments, merchant settlement, and overseas remittance.
The retail test ran at a Hollys coffee kiosk, keeping the normal checkout while moving back-end settlement to blockchain. A cross-border leg converted the won stablecoin to a dollar stablecoin via
@KaiaChain's on-chain liquidity, then paid out to a Vietnamese bank account in three minutes, down from days, cutting fees roughly 87% versus traditional rails.
KB Kookmin is South Korea's largest bank, with about $266 billion in assets. It wants to launch the moment Korea's digital asset law lands.
