Lambda256, the blockchain subsidiary of Dunamu, says it has completed a proof of concept designed to test whether South Korea’s existing card payment infrastructure can be connected to stablecoin-based payments. The project was carried out with the Korea Credit Finance Association and nine card issuers.
Testing the card-to-stablecoin link
According to Lambda256, the joint pilot focused on a technical question: whether the systems already used by card issuers for member services, merchants, payment approvals, settlements and fraud detection could operate alongside a stablecoin payment environment. Rather than examining a single step in the process, the test was set up to cover the full payment and settlement cycle.
The company said the scope included stablecoin issuance and distribution, payment approvals, cancellations and refunds, and settlement procedures. It also extended to the use of policy support funds and card points, as well as on-chain anti-money laundering checks and fraud detection.
Use of SCOPE and CLAIR
For the blockchain side of the pilot, Lambda256 used its SCOPE platform together with CLAIR, its on-chain compliance platform. The company said both systems were upgraded during the project to meet operational requirements from the card industry and were then tested for integration with card issuers’ existing systems.
Lambda256 said the work resulted in an on-chain execution framework covering several operational elements needed for payments infrastructure. These included the creation and transmission of blockchain transactions, gas fee processing, transaction status monitoring, and procedures for cancellations, refunds, settlements and technical failures. It also said the project improved integration flexibility for individual issuers.
What the pilot results suggest
Based on the outcome, Lambda256 said the test supports the feasibility of a standardized platform service that could still allow tailored systems for individual issuers. In its description of the model, card issuers would keep control over core business functions such as payment methods, user interface, approvals, settlements and merchant management, while Lambda256 would manage the on-chain execution layer.
Chief executive Jung Eui-jung said the project was significant because it reduced technical uncertainty around issuer participation in stablecoin payments and settlement processes. The company also said it intends to continue providing technical support for on-chain execution.
Regulatory and operational backdrop
Lambda256 said it will also push for recognition of payment, distribution and settlement roles in future stablecoin regulation. The company framed the latest project as part of a broader effort to adapt blockchain infrastructure for financial-sector use.
It previously obtained SOC 2 Type II certification, which it said validated its ability to operate blockchain infrastructure services in financial and enterprise environments. The latest proof of concept does not by itself establish commercial rollout plans, but it does provide a technical test case for how stablecoin payments might be integrated into existing card networks while leaving issuers in control of customer-facing and settlement functions.
