• Joint proof of concept to validate infrastructure, technology, governance, and compliance systems for stablecoin-based corporate fund settlement
• Testing financial institutions' settlement role and operations — from on-chain settlement to KRW conversion (off-ramp) and AML/FDS (fraud detection system) checks

SEOUL, July 7, 2026 — Lambda256, a blockchain technology subsidiary of Dunamu, today announced that it has begun a proof of concept (PoC) with Kbank and KSNET to test a digital asset off-ramp and on-chain AML/FDS technology. The three companies held a project kickoff meeting on July 6 at Lambda256's Seoul office and will carry out the joint PoC over approximately five months.

The PoC focuses on whether financial institutions can operationally run an off-ramp-linked settlement model that converts stablecoin payment proceeds into Korean won. Beyond verifying digital asset transfer, payment, and settlement functions, the participating bank and payment specialist will jointly examine the settlement process, operating structure, compliance requirements, and roles and responsibilities among the participating institutions. The project aims to help define the operational standards financial institutions will need as Korea's regulatory framework for digital assets continues to take shape.

Each company brings its own area of expertise to the project. Kbank, as the banking partner, will manage the off-ramp operating framework, including foreign exchange (FX) application, KRW disbursement, anti-money laundering (AML) controls, and suspicious transaction reporting (STR). KSNET, a payment specialist that has long operated merchant payment and settlement services, will connect stablecoin payment infrastructure with KRW settlement for merchants, with a particular focus on validating operating policies flexible enough for real-world merchant environments. Lambda256 will support the on-chain settlement execution layer through its digital asset orchestration platform SCOPE and on-chain compliance platform Clair, testing the platforms' effectiveness within a financial institution environment.

The PoC will use USDC and cover the full operational workflow: FX application at the point of payment, settlement request generation, AML/FDS screening, payment approval, on-chain settlement execution, and post-disbursement transaction monitoring and STR filing. The project will also examine practical requirements such as the flexibility of operating policies, the boundaries of responsibility among participating institutions, and auditability.

"In the stablecoin era, the core competitive advantage is not simply the ability to use digital assets, but having the systems in place for financial institutions to operate them safely and transparently," said Charles Chung, CEO of Lambda256. "Lambda256 will continue to advance SCOPE and Clair as an integrated digital asset operating platform connecting on-chain execution with compliance, and will keep laying the groundwork for financial institutions to adopt digital asset services with greater confidence."

"For digital assets to take stable root in the real-world payment ecosystem, robust compliance infrastructure that protects merchants and consumers is essential," said Hankook Park, CEO of KSNET, which is also participating in the project. "Drawing on the settlement expertise we have built in the payments market, we will work with Lambda256 and Kbank to successfully validate a reliable stablecoin off-ramp model."

Separately, Lambda256 previously became the first company in Korea's blockchain industry to obtain SOC 2 Type II certification, validating the infrastructure operating capabilities required for financial and enterprise environments.
