The future of digital asset security is taking a revolutionary leap forward, thanks to a powerful collaboration between Krown Technologies LLC and Quantum eMotion Corp. (QeM). Together, they are advancing the development of two cutting-edge, quantum-resistant cryptocurrency wallets: the Qastle Quantum Hot Wallet and the Excalibur Quantum Cold Wallet. These innovations represent a critical response to the looming threat quantum computing poses to traditional cryptographic systems.
As quantum technology evolves, so too does the risk to blockchain and digital wallets that rely on classical encryption. Standard cryptographic algorithms—such as RSA and ECC—could be broken by sufficiently powerful quantum computers using Shor’s algorithm. This vulnerability has sparked a global race to develop quantum-safe solutions. Krown Technologies and QeM are now at the forefront, combining advanced quantum cybersecurity with real-world blockchain applications.
Excalibur Quantum Cold Wallet: Redefining Offline Security
The Excalibur Quantum Cold Wallet is engineered to become the gold standard in offline cryptocurrency storage. Compact and portable—designed like a standard thumb drive—it supports universal compatibility across devices and operating systems. But what truly sets it apart is its quantum-secure architecture, powered by QeM’s proprietary Quantum Random Number Generator (QRNG).
Traditional cold wallets generate cryptographic keys using pseudo-random number generators (PRNGs), which are deterministic and potentially predictable. In contrast, Excalibur leverages true randomness derived from quantum mechanics—the most unpredictable physical process known. This eliminates vulnerabilities tied to weak entropy, reducing the risk of monetary loss by up to 98% compared to conventional cold wallets.
Recent development milestones include rigorous prototype testing, firmware optimization, and design refinements aimed at ensuring durability, ease of use, and mass manufacturability. With production scaling on the horizon, Excalibur is positioned to become the go-to solution for high-net-worth individuals, institutional investors, and anyone serious about long-term digital asset protection.

Qastle Quantum Hot Wallet: Securing Real-Time Transactions
While cold wallets protect assets at rest, the Qastle Quantum Hot Wallet addresses the urgent need for quantum-resistant security in active environments. Designed for seamless integration with DeFi platforms, exchanges, and everyday blockchain interactions, Qastle brings enterprise-grade protection to online transactions.
Unlike traditional hot wallets vulnerable to remote attacks, Qastle integrates post-quantum cryptographic algorithms—specifically SLHDSA (Stateful Hash-Based Digital Signature Algorithm) and ML-KEM (Module-Lattice Key Encapsulation Mechanism)—both of which are under evaluation by NIST for standardization in post-quantum cryptography.
Additionally, Qastle leverages QeM’s Entropy-as-a-Service (EaaS) platform to continuously feed high-quality, quantum-derived randomness into key generation and encryption processes. This dynamic entropy source ensures that even if a system is compromised, attackers cannot reproduce or predict cryptographic keys.
The wallet is being developed with a strong focus on user experience—offering intuitive interfaces, multi-chain support, and real-time security alerts—making quantum-level protection accessible without sacrificing convenience.
A Strategic Alliance Accelerating Market Adoption
Behind these technological breakthroughs lies a strategic expansion of collaboration between Krown Technologies, Quantum eMotion, and Esposito Intellectual Enterprises (EIE). Announced in April 2025, this partnership significantly boosts the commercial reach and public visibility of both Qastle and Excalibur.
EIE, a global holding company with over 115 subsidiaries and 200+ joint ventures spanning more than 25 industries, brings unparalleled access to media networks, marketing infrastructure, and celebrity influencer channels. Through targeted campaigns and cross-sector integration—from fintech to luxury goods—EIE is driving mainstream awareness and accelerating adoption of quantum-secure wallets.
This alliance also capitalizes on QeM’s recent success in completing a quantum simulation project that validated the resilience of its Sentry-Q cryptographic architecture against known quantum attack models, including Grover’s algorithm—a quantum search method capable of weakening symmetric encryption over time.
The simulation confirmed that keys generated using QRNG technology resist brute-force attacks far more effectively than those based on classical entropy sources. This scientific validation strengthens investor confidence and underscores the urgency of transitioning to quantum-safe solutions before large-scale quantum computers become operational.

Frequently Asked Questions (FAQ)
What makes a wallet "quantum-secure"?
A quantum-secure wallet uses cryptographic methods resistant to attacks from quantum computers. This includes leveraging true quantum randomness (via QRNG) and implementing post-quantum algorithms like ML-KEM and SLHDSA that cannot be easily broken by quantum techniques such as Shor’s or Grover’s algorithms.
How does QRNG improve wallet security?
Traditional wallets rely on software-based random number generators that can be predictable. QRNG uses the inherent unpredictability of quantum physics to generate truly random numbers, making cryptographic keys virtually impossible to guess or reproduce—drastically reducing the risk of theft.
Can I use Qastle for DeFi transactions?
Yes. The Qastle Quantum Hot Wallet is specifically designed for real-time blockchain interactions, including DeFi trading, staking, and smart contract execution. Its integration with post-quantum encryption ensures your active assets remain protected even in high-risk online environments.
Is Excalibur compatible with all cryptocurrencies?
Excalibur is being developed with universal blockchain compatibility in mind. It will support major cryptocurrencies like Bitcoin, Ethereum, and various ERC and BEP tokens, with plans to expand to emerging chains as needed.
When will these wallets be available?
Prototype testing has been completed successfully, and both wallets are progressing toward large-scale production. With EIE’s commercialization support, consumer availability is expected within the next 12–18 months.
Do I need technical expertise to use these wallets?
No. Despite their advanced backend technology, both Qastle and Excalibur are designed with user-friendly interfaces. Whether you're a novice or an experienced crypto holder, setup and daily use will be straightforward and intuitive.
