Krown Technologies is developing EXCALIBUR, a cold wallet designed to bring quantum entropy, native authentication and connected hardware into a more complete digital-asset ownership experience.

The aim is not simply to create another storage device. EXCALIBUR is being developed as part of Krown’s wider self-custody architecture, connecting secure hardware, wallet authentication, transaction workflows and future Krown ecosystem products in a more deliberate way.For digital assets, self-custody is only as strong as the systems that protect access, keys and authorization. EXCALIBUR is being built around that principle.

Quantum Entropy at the Foundation

Krown’s partnership with Quantum eMotion (TSXV:QNC NYSE:QNC FSE:34Q0) supports the planned integration of its QRNG2 technology into EXCALIBUR.

That matters because randomness plays a foundational role in cryptographic key generation. In wallet security, the quality of entropy can influence the strength of the keys protecting digital assets. By incorporating quantum-generated randomness into the planned architecture, EXCALIBUR is being designed with security at the foundation, not added as an afterthought.

This reflects the wider direction of the Krown ecosystem: building digital-asset infrastructure for a world where ownership, authentication and long-term protection need to be taken seriously.

Native Authentication and Connected Hardware

The EXCALIBUR roadmap includes planned integration with QwickAuth, alongside fingerprint and facial recognition.

Those features are being designed to support a more controlled and intentional self-custody experience. Cold-wallet security should not only be about keeping assets offline. It should also make authorization clear, deliberate and difficult to misuse.

Krown is also developing EXCALIBUR with connectivity to Krown Watch for transaction workflows. That connection points to a broader product vision where secure storage, wearable access and user authorization can work together across Krown hardware.

The device itself is being designed as a distinctive black-on-black handheld cold wallet, giving EXCALIBUR a physical identity that matches the seriousness of its role inside the ecosystem.

From Prototype Package to Physical Validation

The EXCALIBUR prototype handoff package is now prepared.

The next phase is supplier integration, physical prototyping and validation as Krown works toward production. That stage is important because the product now moves from design architecture into the practical work of hardware development.

This is where decisions around components, manufacturing, ergonomics, authentication, transaction flows and security implementation begin to take physical form.

Krown will share further progress as development advances.

Why EXCALIBUR Matters

Self-custody remains one of the most important ideas in digital assets, but it is also one of the most demanding.

People want direct control over their assets. They also need the tools protecting that control to be carefully designed, understandable and secure enough for the value they are responsible for.

EXCALIBUR is being developed for that responsibility.

It sits alongside Krown Network, Qastle Wallet, Krown Watch and the wider Krown ecosystem as part of a broader move toward digital ownership that is more personal, more secure and more practical.

Qastle Wallet supports everyday access. Krown Watch brings Web3, AI and digital ownership closer to daily life. EXCALIBUR is being developed for the cold-wallet layer, where protected key storage and deliberate authorization become central.

Together, those products reflect Krown’s ambition to build a connected, quantum-secure ownership experience across software, hardware and infrastructure.

Direct Control, Designed With Security First

The ambition behind EXCALIBUR is clear: give people direct control over their digital assets through thoughtfully designed hardware and a security architecture built from the foundation up.

That means taking entropy seriously.

It means treating authentication as part of the ownership experience.

It means connecting hardware products in ways that support real user workflows.

And it means building self-custody tools for people who want more than access. They want control they can trust.
