Krown Technologies and Quantum eMotion Launch Qastle - The First Hot Wallet Secured by Quantum Entropy and Post-Quantum Encryption

Positioning both companies to disrupt a market expected to exceed $100 billion by 2033

Monroe, Louisiana and Montreal, Quebec--(Newsfile Corp. - November 3, 2025) - Krown Technologies, Inc. ("Krown") and Quantum eMotion Corp. (TSXV: QNC) (OTCQB: QNCCF) (FSE: 34Q0) ("QeM") today announced the global launch of Qastle, the world's first quantum-secured hot wallet to leverage Quantum Entropy-as-a-Service and Post-Quantum Cryptography to safeguard digital assets against emerging cyber and quantum-based threats. Qastle is now live and available to users worldwide at https://qastlewallet.com.

Redefining Security in the Hot-Wallet Market

Hot wallets remain the most commercially active segment of the $12.6B global crypto-wallet industry — a sector projected to grow past $100B by 2033. However, their permanent internet connectivity has historically made them the most targeted wallets for key theft, phishing-based drain attacks, and exploit-driven compromises.

Qastle disrupts this paradigm by integrating continuous, on-demand quantum entropy, delivered via QeM's EaaS cloud infrastructure, combined with post-quantum cryptographic key protection. This architecture provides randomness and key security exceeding the capabilities of both traditional software-based random number generators and conventional hardware modules.

The Quantum Advantage — Delivered Over the Cloud

Qastle derives its security foundation from QeM's QRNG2 true-entropy engine, accessed securely through Entropy-as-a-Service rather than embedded local hardware. The system generates non-deterministic, physics-rooted randomness for wallet seed creation, session keys, signing flows, and ongoing key refresh cycles.

This ensures:

• Seeds and keys that cannot be predicted, cloned, or reconstructed
• Continuous resistance to both classical and quantum-computing-enabled attacks
• Compatibility with both mobile and desktop environments

Qastle further integrates post-quantum encryption safeguards to future-proof transactions and identity against the anticipated "Q-Day" decryption event.

"We didn't just launch another wallet — we launched a new security era," said James Stephens, Founder & CEO of Krown Technologies. "Qastle brings quantum-grade security to everyday users, without complexity. It is the first hot wallet designed to stay secure both now and in the post-quantum future."

"This launch demonstrates the scalability and market readiness of our quantum entropy platform," said Francis Bellido, CEO of Quantum eMotion. "Qastle proves that quantum cybersecurity is no longer theoretical. It is commercial, it is accessible, and it is here today."
