WISeKey Joins the Hedera Council Network of Strategic and Community Partners

Geneva, Switzerland – September 4, 2026 — WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY), a global leader in cybersecurity, digital identity and IoT, today announced that it has joined Hedera Council’s network of Strategic and Community Partners.

The growth of Hedera Council’s network of Strategic and Community Partners continues, with the addition of two new partnerships, WISeKey and SpaceDev. This partnership program leverages the skills, networks and resources of industry leaders to drive real-world adoption of Hedera. 

Hedera Council’s latest collaborations expand Hedera’s capabilities for secure, decentralized infrastructure for real-world use cases, while enhancing Hedera’s technical offerings. Hedera’s latest Strategic Partner is WISeKey, a global expert in cybersecurity, digital identity and IoT solutions. As Hedera’s fourth Strategic Partner, WISeKey joins the Global Blockchain Business Council, Halborn and the Institutes RiskStream Collaborative.

Accelerating Authentication and Digital ID on Hedera

Based in Switzerland, WISeKey is strongly embedded in Web3 infrastructure, offering secure authentication and identification solutions for IoT, blockchain and AI. SEALCOIN AG, one of WISeKey’s established subsidiaries, focuses on the development of the SEALCOIN platform, which enables the autonomous exchange of verified, high value data secured by post-quantum cryptography. 

“Becoming a Strategic Partner of the Hedera Council reinforces WISeKey’s commitment to building trusted infrastructure for an increasingly connected and autonomous world,” said Carlos Moreira, Founder and CEO of WISeKey Group.  By combining WISeKey’s expertise in digital identity, cybersecurity, PQC-secure semiconductors and space-based IoT with Hedera’s enterprise-grade distributed ledger technology, we can accelerate the deployment of trusted digital ecosystems where devices, machines and organizations can identify, authenticate and transact securely at global scale. This partnership is an important step in turning decentralized technologies into real-world infrastructure for the digital economy.”

This strategic partnership builds on an existing use case in the Hedera ecosystem. Earlier this year, the Hashgraph Group launched the QAIT Q-Day Security Assessment Platform on the SEALCOIN Quantum Marketplace. The platform was designed to help enterprises, governments and critical infrastructure operators evaluate, monitor and mitigate cybersecurity risks associated with the emergence of quantum computing. 

Jonathan LLamas, Chief Product and Strategy Officer at SEALCOIN AG, added: “SEALCOIN was created around a simple premise: billions of connected devices and autonomous machines will increasingly need to transact with each other without sacrificing identity, security or trust. Hedera has been an active contributor to this vision, with a dedicated team of experts from its ecosystem working alongside us in the development of the SEALCOIN platform. By combining trusted device identity with Hedera’s scalable distributed infrastructure, we are building the foundations for machines to authenticate, exchange value and transact autonomously at global scale. This Strategic Partnership is a natural continuation of that collaboration and an important step toward making trusted machine-to-machine commerce a reality.”
