Krown plans quantum-secured cold wallet EXCALIBUR

Krown Technologies said Sept. 9 it has finalized development and plans production of EXCALIBUR, a cryptocurrency cold wallet built with Quantum eMotion’s QRNG2 technology. The device is designed to combine quantum randomness, biometric authentication and native QwickAuth as Krown pushes deeper into self-custody security.

Why it matters: - EXCALIBUR is being positioned as a dedicated self-custody wallet that aims to make advanced crypto security easier to use. - The product combines quantum randomness, authentication and hardware controls in one device. - Krown is targeting a growing need for stronger protection of private keys as digital asset security becomes more important.

What happened: - Krown Technologies Inc. announced finalized development and planned production of EXCALIBUR on Sept. 9, 2026. - EXCALIBUR is a cryptocurrency cold wallet being developed with quantum random number generation technology from Quantum eMotion Corp. - The wallet is designed to give digital asset owners direct control over their private keys through a dedicated hardware experience. - James Stephens, Krown Technologies CEO, said the goal is to make advanced protection practical and easy to use.

The details: - EXCALIBUR is built around Quantum eMotion’s QRNG2 technology. - QRNG means quantum random number generator. - Quantum eMotion’s technology uses electron quantum tunneling to generate entropy for cryptographic key generation. - The planned security architecture also includes private-key isolation, authentication and transaction authorization. - The companies’ strategic agreement, announced in April 2026, gave Krown an exclusive worldwide license to commercialize QRNG2 technology across blockchain, decentralized finance, wallets and related applications. - Quantum eMotion describes quantum entropy as a foundation that works alongside classical and post-quantum cryptography. - Planned product features include native QwickAuth integration, biometric authentication, on-device transaction review and Krown Watch interoperability. - The biometric package includes a thumb-oriented fingerprint sensor and a camera intended to support facial recognition. - The device is planned with a dedicated display for reviewing transaction details before authorization. - The hardware design includes a black-on-black enclosure, physical controls, USB-C connectivity and a built-in microphone. - The production roadmap includes prototype assembly, hardware and software integration, security evaluation and manufacturing validation. - Final specifications, supported assets, pricing and commercial availability will be announced after those milestones are completed. - Krown says the product is intended to bring quantum randomness into an everyday self-custody experience.

Between the lines: - The announcement shows Krown leaning on Quantum eMotion’s QRNG2 as a differentiator in wallet security. - The company is also signaling that EXCALIBUR is meant to be more than a software wallet, with hardware-first controls and transaction review built in. - Security claims will ultimately depend on the full cryptographic design, not just the randomness source.

What's next: - Krown will move through prototype assembly, integration, security review and manufacturing validation. - The company will disclose final specs, supported assets, pricing and launch timing once development milestones are complete. - Krown and Quantum eMotion are continuing to commercialize QRNG2 across blockchain and wallet applications under their licensing deal.

The bottom line: - Krown is betting that quantum randomness plus biometric hardware can create a more usable cold wallet for self-custody investors.
