BTQ Technologies Corp. (BTQ) has announced that its Quantum Secure Stablecoin Network (QSSN) has been highlighted by the U.S. Post-Quantum Financial Infrastructure Framework (PQFIF) as a model for quantum-secure tokenized deposits. Concurrently, the Quantum Industrial Standard Association (QuINSA) has unanimously advanced QSSN as a global standard initiative, placing it on the ITU / ISO / ETSI / IEEE track.
QSSN is a framework that upgrades privileged issuer controls with post-quantum signatures. It is designed to protect stablecoins and deposit tokens against quantum threats without disrupting user workflows. The approach involves co-signing privileged actions with both today’s standard keys and a post-quantum signature, providing a standards-based path to meet U.S. quantum-resilience mandates without a system overhaul.
The PQFIF’s recognition of QSSN signals that quantum-secure controls are moving from concept to implementation in U.S. financial infrastructure. BTQ is steering the technical design and standardization roadmap, aiming to be a key architect of globally harmonized, interoperable quantum-secure communications standards. The company is targeting Q4 2025 for pilot projects with stablecoin issuers, with the goal of expanding into the $280 billion stablecoin market.
This development aligns with a broader push for quantum resilience in financial infrastructure. It is aligned with NIST PQC standards, Korea’s Quantum Technology Industry Act, and EU quantum network initiatives, reinforcing BTQ’s role in cross-border interoperability for digital assets.
