How entropy-as-a-service boosts wallet security for the quantum era

Understanding the Future of Hot Wallets

Qastle brings a new level of security to the hot wallet experience while ensuring that users do not have to change their habits. As the hot wallet market continues to grow, projected to reach $100 billion by 2033, the risks associated with hot wallets are becoming increasingly serious. Their constant connection to the internet makes them attractive targets for hackers, leading to concerns about key theft and phishing attacks.

As quantum computing technology advances, a worrying strategy known as “harvest-now, decrypt-later” has surfaced, where cybercriminals capture encrypted data now with the intention of decrypting it with future quantum capabilities. Notable figures in the crypto community, including Ethereum co-founder Vitalik Buterin, have alerted users about the potential obsolescence of current encryption methods, such as elliptic curves, which underpin much of today's cryptocurrency security.

Qastle: A Quantum-Ready Solution

Entering the market just as these concerns peak, Qastle is the first hot wallet to offer quantum-secured protection without altering the user experience. The app maintains a familiar interface while strengthening security where vulnerabilities typically arise, eliminating the need for complex setups or new hardware that might dissuade users.

Qastle relies on Quantum eMotion’s QRNG2 technology, which offers increased randomness for the creation of keys, session management, and signing processes. Many existing wallets depend on software-based randomness, which can be predictable and therefore insecure. In contrast, Qastle harnesses quantum-generated entropy, providing a robust layer of protection against attacks both now and in the future, utilizing quantum-resistant algorithms seamlessly in the background.

Building Confidence and Utility

Krown Network, which underpins Qastle, combines innovative technology with external validation to build user trust. It is working through ISO 27001, SOC 2, and AWS Well-Architected assessments—important for high-value users and organizations evaluating custody options.

Moreover, Qastle is more than just a hot wallet; it’s part of an expanding roadmap. Users can already download the wallet and enjoy its core features, with plans to launch further functionalities on January 3, when the Krown Network's mainnet goes live. Features such as staking, validation, and on-chain transfers will soon connect the wallet to a larger framework, fostering greater utility.

🚀 Upcoming Launch: KrownDEX, a revolutionary quantum-secured decentralized exchange powered by QEM_Corp’s QRNG2 Entropy Engine, is set to launch on January 3, 2026!

The app has generated thousands of downloads shortly after its release and is available across major app platforms like Android, the Chrome Web Store, and the Apple App Store/iOS.

As the stakes for hot wallet users rise with evolving cyber threats, Qastle strives to advance security measures without complicating user interactions. This innovative approach seeks to merge today’s user experience with the protection required for the realities of tomorrow’s digital landscape.
