Davos, Switzerland – January 20, 2025 –– WISeKey International Holding (“WISeKey” or the “Company”), a leading global cybersecurity, AI, and IoT company, today announced that its subsidiary SEALCOIN AG, a leader in blockchain and IoT innovation, launches the presale of SEALCOIN, the first-ever Post-Quantum Cryptography (PQC) Token. The announcement was made during the Web3 Hub Davos 2025, where Carlos Moreira, Founder of SEALCOIN AG and CEO of WISeKey SA, delivered a keynote speech.

Mr. Moreira participated in the fireside chat, “Future-Proofing Security: Innovations in Post-Quantum Technology and IoT,” held on January 20, 2025. During his speech, Mr. Moreira emphasized the transformative potential of SEALCOIN in securing IoT transactions through the integration of post-quantum cryptography and sustainable blockchain technology. Designed as a Hybrid Transactional Internet of Things (TIoT) token, SEALCOIN delivers unparalleled post-quantum security, trust, and efficiency, overcoming scalability challenges and safeguarding billions of interconnected devices in the digital economy.

“Launching SEALCOIN at Davos, a hub of global collaboration, underscores its significance in shaping the future of secure IoT transactions. By combining post-quantum cryptography and blockchain innovation, SEALCOIN ensures a scalable and resilient ecosystem to meet the demands of tomorrow’s digital world,” said Mr. Moreira.

With the advent of quantum computing, traditional encryption methods are becoming obsolete. SEALCOIN integrates post-quantum cryptographic algorithms, such as FALCON and ML-DSA 87 (formerly known as Dilithium 5), ensuring resilience against quantum-based attacks. This positions SEALCOIN as a secure, forward-looking solution for IoT ecosystems, particularly in critical industries like healthcare, logistics, and smart cities. SEALCOIN’s hybrid model balances scalability and decentralization, while its energy-efficient design minimizes environmental impact. The token seamlessly integrates into IoT ecosystems, providing trust and transparency for billions of connected devices.

The presale offers accredited investors and strategic partners a unique opportunity to join this groundbreaking initiative. Attendees at Davos will witness live demonstrations of SEALCOIN’s real-world applications, including its role in secure IoT data exchange, device authentication, and transaction verification within a post-quantum-ready blockchain framework.
