Innovative Quantum-Secure Cryptocurrency Wallets Unveiled
Krown Technologies LLC, in partnership with Quantum eMotion Corp. (TSXV: QNC) (OTCQB: QNCCF) (FSE: 34Q0), a leader in quantum cybersecurity, has made significant strides in developing two revolutionary quantum-secure cryptocurrency wallets: the Qastle Quantum Hot Wallet and the Excalibur Quantum Cold Wallet. This initiative represents a crucial advancement in protecting digital assets from the potential risks posed by quantum computing.
Excalibur Cold Wallet: A New Benchmark in Security
The Excalibur cold wallet, which is compact and designed like a thumb drive, is setting a new standard for cryptocurrency storage with its universal compatibility and quantum-secure design. Utilizing QeM’s Quantum Random Number Generator (QRNG), Excalibur can reduce the risk of financial loss by up to 98% when compared to conventional cold wallets. Recent efforts have been directed towards refining its design and gearing up for large-scale production after successful prototype evaluations. “Excalibur represents the most secure method for storing digital assets, without question,” stated James Stephens, CEO of Krown Technologies.
Qastle Hot Wallet: Enhanced Security for Online Transactions
The Qastle Quantum Hot Wallet is being engineered to provide quantum-level security for online transactions and real-time asset management. It aims to seamlessly integrate with blockchain ecosystems while employing QeM’s Entropy-as-a-Service (EaaS) and post-quantum cryptographic techniques to shield users from potential quantum attacks that could exploit traditional hot wallets. Recent developments include the incorporation of advanced post-quantum algorithms like SLHDSA and ML-KEM, which ensure strong signatures and secure backups. Qastle is well-positioned to satisfy the increasing demand for secure and user-friendly hot wallets in decentralized finance (DeFi) and other sectors.
A Partnership Driving Technological Advancement
The enhanced collaboration between Krown Technologies and QeM, supported by a strategic alliance with Esposito Intellectual Enterprises (EIE) announced on April 23, 2025, is accelerating the commercialization and visibility of these innovative quantum-secure wallets. EIE, a global holding company with over 115 entities and more than 200 joint ventures across various industries, will utilize its extensive media, marketing, and industry networks to enhance the adoption and commercialization of Krown Technologies’ Qastle and Excalibur wallets. This integration aims to expand their reach across different sectors and boost their visibility through strategic partnerships and celebrity endorsements.
This collaboration also capitalizes on QeM’s recent successful quantum simulation project, which confirmed the robustness of its Sentry-Q cryptographic framework against quantum threats, including Grover’s algorithm. This project further solidifies QeM’s standing in quantum cybersecurity and underscores Krown’s commitment to advancing secure blockchain solutions. “Krown Technologies and Quantum eMotion are transforming the landscape of digital asset security,” remarked Dr. Francis Bellido, CEO of Quantum eMotion. “The progress made with Qastle and Excalibur reflects our collective ambition to establish a quantum-secure future for blockchain technologies.”
Future Developments on the Horizon
Krown Technologies is currently in the final stages of designing the Qastle wallet, with prototype testing set for the third quarter of 2025. Meanwhile, production of Excalibur is ramping up to meet global demand, with broader availability anticipated in early 2026. Both wallets are designed to address the growing concerns regarding quantum vulnerabilities in cryptocurrency, especially in light of recent research from Google indicating that quantum computers may be able to breach traditional encryption more easily than previously thought.
