WISeKey Joins Hedera Council as Strategic Partner

Geneva, Switzerland, September 4, 2026, WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY), a leading global provider of cybersecurity, digital identity, and IoT solutions, has joined the Hedera Council’s network of strategic and community partners. This move marks the addition of two new partnerships, WISeKey and SpaceDev, to the growing network.

The collaboration between WISeKey and Hedera aims to expand the capabilities of secure, decentralized infrastructure for real-world applications. WISeKey, based in Switzerland, is a global expert in cybersecurity, digital identity, and IoT solutions. As Hedera’s fourth strategic partner, WISeKey will leverage its expertise to enhance the technical offerings of the Hedera platform. The partnership also includes WISeKey’s subsidiary, SEALCOIN AG, which focuses on developing the SEALCOIN platform, a solution enabling 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,” stated Carlos Moreira, Founder and CEO of WISeKey Group. “By combining WISeKey’s expertise in digital identity, cybersecurity, post-quantum 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 a global scale.”

This strategic alliance 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. This 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, commented: “SEALCOIN was created with the vision that 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 a 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.”
