BTQ Technologies Corp. (NASDAQ: BTQ) announced it has been selected to provide post-quantum cryptography security technology for South Korea's first bank-led Korean won stablecoin proof-of-concept.

The quantum technology company will supply its Quantum Secure Stablecoin Settlement Network (QSSN) and provide strategic advisory support for the initiative involving iM Bank, a South Korean commercial bank, and Finger Inc., BTQ's Korean strategic partner.

The proof-of-concept will be built on the Kaia mainnet, a blockchain network created through the merger of Klaytn and Finschia. Klaytn was originally developed by Kakao, while Finschia is associated with LINE, connecting the project to messaging and digital platform ecosystems in Korea and Japan.

"Post-quantum migration requires more than a cryptographic upgrade. It requires coordination across infrastructure, implementation, and institutional stakeholders," said Olivier Roussy Newton, CEO of BTQ Technologies. "BTQ is providing both strategic advisory support and QSSN as the post-quantum security architecture, while helping lead coordination across the three-way partnership."

The initiative aims to validate infrastructure for Korean won stablecoin issuance and distribution, including real-time reconciliation between bank reserves and blockchain-issued supply. The system will integrate post-quantum cryptography alongside existing ECDSA cryptographic frameworks to address future quantum computing threats while maintaining operational continuity.

BTQ's QSSN uses a dual-signature design that allows existing infrastructure to operate in parallel with post-quantum cryptography signatures aligned with standards from the U.S. National Institute of Standards and Technology. The company stated that QSSN was previously highlighted in the U.S. Post-Quantum Financial Infrastructure Framework as a model architecture.

iM Bank is a subsidiary of DGB Financial Group and traces its roots to Daegu Bank, established in 1967 as Korea's first regional bank. Finger Inc. has provided financial IT solutions since 2000 and was reportedly the first company in Korea to deliver smartphone banking services.
