Krown Technologies & Quantum eMotion Announce the Official Launch of Qastle - The World's First Quantum-Secured Hot Wallet for the Masses, on November 1st, 2025

By: Newsfile

Monroe, Louisiana and Montreal, Quebec--(Newsfile Corp. - October 8, 2025) - Krown Technologies, Inc. and Quantum eMotion Corp. (TSXV: QNC) (OTCQB: QNCCF) (FSE: 34Q0) ("QeM") are proud to announce the global release of Qastle, the world's first quantum-secured hot wallet designed for everyday use. Following extensive development and successful final testing, Qastle will officially launch on November 1st, 2025.

Unlike any wallet before it, Qastle is universally available-on iPhone, Android, tablets, browser extensions, laptops, desktops, and virtually every platform where digital assets are stored and transacted. With this groundbreaking release, secure digital asset storage is no longer limited to the technically elite; it is now accessible to everyone, everywhere, and without compromise. It is the safest hot wallet in the world.

A First-of-Its-Kind Breakthrough

Qastle represents the first time that post-quantum cryptography (PQC) and quantum random number generation (QRNG) are combined in a hot wallet built for the mainstream. With hackers and state actors racing toward exploiting the coming era of quantum computing, Qastle stands as a fortress against tomorrow's threats today.

The launch also marks a significant milestone for both companies: Qastle represents the first positive cash flow channel for Krown Technologies and Quantum eMotion.

James Stephens, Founder & CEO of Krown Technologies, said:

"Qastle isn't just another wallet-it's the dawn of a new era in blockchain security. On November 1st, the world will see what true quantum protection looks like, and it will be available in everyone's pocket, on every device they own."

Francis Bellido, CEO of Quantum eMotion, added:

"Qastle is the culmination of years of research and collaboration, marrying QeM's pioneering QRNG technology with Krown's blockchain innovation. This launch proves that quantum-safe security is not just theoretical-it is real, scalable, and ready for mass adoption."
