The company confirmed it is working with [Avalanche](https://coinlaw.io/avalanche-avax-statistics/), a global blockchain network, and OpenAsset to enable stablecoin usage across its card systems. The planned system introduces a **hybrid payment model** where users can connect a stablecoin wallet to their credit card. This allows them to **choose between stablecoin payments and traditional credit transactions** using a single card. The infrastructure is designed to operate on a **public blockchain**, supporting the full payment lifecycle including: - **Stablecoin wallet top ups**. - **Payments at merchants**. - **Settlement processes**. The company emphasized that the system goes beyond experimentation and is aimed at **real world deployment**, signaling a major step toward mainstream adoption of digital assets in everyday payments. ## How the Hybrid Payment System Works? The hybrid model is built to maintain the familiar experience of credit card usage while introducing the benefits of digital assets. According to earlier disclosures, the system will **prioritize stablecoin balances** in the linked-wallet when making payments. If the stablecoin balance is insufficient, the remaining amount will be automatically **charged to the [credit card](https://coinlaw.io/credit-card-vs-debit-card-statistics/)**, ensuring uninterrupted transactions. This approach helps reduce friction for users by: - **Preserving existing card benefits such as rewards and ease of use**. - **Lowering the barrier to entry for [stablecoin adoption](https://coinlaw.io/stablecoin-statistics/)**. - **Offering flexibility between traditional finance and digital assets**. ## Built for Future Financial Services KB Kookmin Card noted that the payment model is designed to be **expandable**, allowing integration with a wider range of financial services in the future. These may include additional features tied to: - **Advanced settlement systems**. - **Expanded digital asset services**. - **Broader blockchain network integrations**. The company also plans to **continue expanding partnerships with global blockchain networks**, reinforcing its long term commitment to digital finance innovation. ## South Korea’s Growing Stablecoin Push The move comes as South Korea actively works toward establishing a **[regulated stablecoin market pegged to the Korean won](https://coinlaw.io/south-korea-stablecoin-launch-banks-tech-unite/)**. Policymakers are currently drafting the **Digital Asset Basic Act**, which is expected to provide a legal framework for stablecoin issuance and usage. The initiative is part of a broader effort led by President Lee Jae myung to **protect monetary sovereignty** in an increasingly digital financial landscape. As regulations take shape, major banks, fintech firms, and payment providers are preparing to **launch stablecoin-based products**, positioning themselves ahead of anticipated approval. ## CoinLaw’s Takeaway In my experience, this is one of the clearest signals yet that **stablecoins are moving from theory to everyday utility**. What I find particularly important is how KB Kookmin Card is not forcing users to change behavior. Instead, it blends stablecoins into something people already trust and use daily. I believe this hybrid approach could be the **turning point for mass adoption**, especially in markets like South Korea where digital infrastructure is already strong. If executed well, it may set a blueprint for how traditional finance and blockchain can truly work together. Definition of Layer 1.
