Wisekey’s subsidiaries Wisesat and Sealsq launch new satellite with SpaceX, so that the very first Depin can become out of space and make the communication of the Quantum-Safe Space Adving possible

SEALSQ and WISESAT lay the foundation for a new generation of cyber resilient, quantum-ready space systems, which worldwide digital confidence of a job to redefine a job

Geneva, Switzerland, 23 June 2025 – Wiskey International Holding Ltd (“Wiseeyy”) (Six: Wihn, Nasdaq: WKE), a leading global cyber security, Blockchain and IoT Company, announces his last generation Saite Saite today “) Satellite 3 Aboard SpaceX has announced. Mission, June 23 at 11:18 PM Cest from Vanderberg, California. This mission represents a breakthrough in spaces -based cyber security and decentralized infrastructure, which marks the first satellite to enclose Kwantum Rootkey from Sealsq’s Corp. (Nasdaq: Laes) (“Sealsq”), another subsidiary of Wiseey.

The new satellite includes advanced technology with which Sealcoin token can exchanges directly from space, in collaboration with Hedera. Note that Sealcoin AG, also a subsidiary of Wiseey, focuses on decentralized physical internet with Depin technology and the development of the Sealcoin platform. This innovation establishes the first decentralized physical infrastructure network (Depin) of the world, launched from a job to transform the role of satellites in decentralized finances and safe digital identity.

At the same time, the mission is a crucial step forward when securing space communication through the implementation of cryptography after the quantum (PQC). PQC is crucial for protecting satellite communication against future threats of quantum computers, which is expected to make the current coding methods such as RSA outdated. Ensuring data integrity and confidentiality is essential in the space environment and PQC supplies quantum -resistant algorithms that can be integrated into existing systems, so that a seamless transition and protection can be brought against both current and emerging risks.

This satellite architecture supports the integration of PQC within a hybrid framework that enables safe communication between orbital and land -based infrastructure. By entering PQC algorithms directly in satellite hardware, the cryptographic processing is isolated from critical systems, which improves security and the vulnerabilities is minimized. This approach also makes safe, important generation, distribution and management, essential functions for trusted data exchange between satellites and earth stations possible.

The cryptographic algorithms that are tested on board follow the latest standards under development by the US National Institute of Standards and Technology (NIST), so that the technology is tailored to global efforts for future -proof digital infrastructure. With this mission, Wisesat and Sealsq show how PQC can not only be used in terrestrial networks, but also extended to a job for the coming years of critical communication.

Carlos Moreira, founder and CEO of Wiseeyy, noted: “This launch is not only a milestone for decentralized infrastructure in the room, but also a strategic step in the direction of making space communication communication-quantum result. By the embedded topping of the blocking-based on-basated-based-based way to make with the space tension, and space technology change. “

The representation of Wisesat at the launch was David Fergusson, administrative director of Wiseey, and executive director, M&A at Generational Equity. At Mr. Fergusson was Jon Templeman, CEO of Savior Products and a pioneer in battery technology. Mr. Templeman’s newest innovation is an industrial ‘shock and vibration management system’ for use on all vehicles of cars to missiles, increasing the lifespan and reducing material costs.

Mr. Fergusson noted: “Wisesat’s groundbreaking innovation, in which the progress of cryptography after quantum is excited, continues to set a precedent for the future of trusted communication and data transfer. And it is an honor to be in his own law in this historical launch by Jon Templeman, whose progress technology will be in front of his own law, whose progress has been in front of whose progress, whose progress has been in progress

The latest satellite launch is part of a growing Wissat -Constellation that provides sovereign, safe and scalable satellite services for IoT, digital identity and trusted data transfer. The launch strengthens the capacities of Europe in space and cyber security and promotes technological independence and leadership in the age of Kwantum Computing.
