VANCOUVER, BC, Oct. 1, 2025 - BTQ Technologies Corp., a global quantum technology company focused on securing mission-critical networks today, announced the world's first large scale trial of a quantum secure stablecoin settlement network, alongside a coordinated Proof of Concept applying post-quantum cryptography to partial banking networks to develop PQC services. In partnership with Finger Inc. Group (KOSDAQ:163730), the program will validate the Quantum Secure Stablecoin Network ("QSSN") for high-volume settlement with issuer controls and compliance features, while introducing PQC services to banking environments incrementally so existing customer and merchant experiences remain unchanged.

Finger joins Danal as an early participant in BTQ's QSSN pilot, which is expected to expand with additional partners and progress from PoC to commercialization in line with QUINSA guidelines and industry initiatives such as PQFIF. As Korea's largest banking-solutions developer serving all major financial institutions, Finger strengthens the institutional foundation of the QSSN ecosystem and aligns with the country's evolving regulatory focus on bank-led stablecoin security. With Finger representing the banking channel and Danal, Korea's leading mobile billing company, representing the commercial channel, BTQ is now positioned across both sides of the market to deliver post-quantum security solutions and support future commercialization.

Regulation, PQC readiness, and standards alignment

• Regulatory momentum: Supervisors and market infrastructures are moving to post-quantum cryptography to mitigate harvest-now decrypt-later risk. Banks need a migration path that preserves today's customer experience.
• Standards alignment: QSSN's design aligns with global standardization efforts for quantum-secure digital money, including initiatives advanced through QUINSA, and has been highlighted by U.S. PQFIF as an architecture that supports issuer controls and compliance-ready integrations.
• Operational continuity: The PoC focuses on partial networks to prove that PQC can be introduced incrementally with merchant-class throughput and latency, keeping mobile and online banking interfaces unchanged for customers and staff.
• Pilot to commercialization: QSSN pilots with Finger and Danal are structured to transition from PoC to controlled production deployments, subject to partner readiness and applicable approvals.
• Standards to policy: Workstreams are designed to align with QUINSA guidance and complementary industry forums such as PQFIF, supporting pathways for policy and potential legislative incorporation where appropriate.

QSSN is BTQ's quantum-secure settlement layer for stablecoins, tokenized deposits, and other digital money instruments. It provides:

• Post-quantum cryptography for long-term security;
• Issuer-level controls such as mint/burn permissions, velocity limits, and blacklist/whitelist rules;
• Compliance-ready hooks to support existing regulatory workflows;
• Drop-in integration that preserves current user and merchant flows.
• QSSN pilots currently include Danal and Finger, with additional ecosystem participants expected as the program advances toward commercialization in line with QUINSA guidance and PQFIF industry practices.
