South Korea's largest financial group KB completes Korean won stablecoin payment verification: cross-border remittance compressed to 3 minutes via Kaia, with fees reduced by 87%

South Korea's largest financial group, KB Financial, announced today (17th) that it has completed a full-process technical proof-of-concept (PoC) for a Korean won stablecoin spanning issuance, offline payments, merchant settlement, and overseas remittance, with cross-border remittance fees reduced by approximately 87%. (Background: South Korea's four major banks will meet with Tether and Circle executives this week to discuss the issuance and application of USD/KRW stablecoins) (Background: Kakao Group announced the launch of a stablecoin "anti-bank alliance," targeting payments, remittances, and capital markets) Announced that it has partnered with electronic payment provider KG Inicis, Layer 1 public chain Kaia, and digital asset solutions company OpenAsset to complete a technical proof-of-concept (PoC) covering the full process of Korean won stablecoin payments. KB Financial Group of Korea officially announced today (17th) that this verification covers four major components: Korean won stablecoin issuance, offline payments, merchant settlement, and overseas remittance, integrating financial services that were previously scattered across different systems into a single workflow. The consumer-side operating experience remains virtually unchanged, while the underlying settlement architecture has been fully switched to automated smart contract execution. The offline payment scenario was demonstrated using the self-service ordering kiosks of coffee chain brand Hollys. Consumers do not need to install any digital wallet—they can simply scan a QR Code to complete payment; on the backend, smart contracts automatically trigger the settlement process, with merchant collection and reconciliation completed on-chain without manual intervention. This design deliberately lowers the technical barrier for consumers. KB Financial's logic is: if users don't even need to install an App, then blockchain is just a "faster, cheaper behind-the-scenes pipeline" to ordinary users, rather than a new product they need to learn. Cross-border remittance is the most compelling figure in this PoC. The verification process is as follows: first, the Korean won stablecoin is exchanged for a USD stablecoin via Kaia's on-chain liquidity, then transferred into an actual bank account through a local Vietnamese partner. The entire process takes no more than 3 minutes, with fees approximately 87% lower than traditional SWIFT wire transfers. By comparison, current SWIFT cross-border remittances typically take 1 to 3 business days, involve commissions taken by multiple correspondent banks along the way, and have an opaque fee structure. Kaia plays the role of a liquidity hub in this verification. Its predecessor Klaytn has in recent years actively transformed into Asia's cross-border payment infrastructure, having completed a Korea-Vietnam cross-border stablecoin pilot in April this year; this collaboration with KB represents a scaled-up continuation of that effort. KB Financial explicitly stated that one purpose of this PoC is to "be able to launch services immediately the moment regulations come into effect." South Korea's "Digital Asset Basic Act" is currently stalled due to disputes over stablecoin issuance eligibility, with the Bank of Korea insisting that only banks be allowed to issue Korean won stablecoins; the legislative timeline is estimated to be pushed back to late 2026 or even early 2027. In other words, what KB Financial is doing is: building the system and getting the processes running during the regulatory gap period, so that once regulations pass, services can launch directly and seize the first-mover advantage. This "preparatory" strategy also implies that KB is internally relatively optimistic about the ultimate direction of regulation. But competitors are equally swift. Kakao Group recently announced the launch of its own Korean won stablecoin initiative, targeting three major scenarios—payments, remittances, and capital markets—directly confronting the bank alliance head-on. Before regulations take effect, the Korean won stablecoin market has already quietly entered the positioning phase.
