/EIN News/ -- SEALCOIN Unveils Major Milestones: From Satellite-Powered IoT Transactions to
Launch of Marketing Campaign Ahead of Token Sale

Geneva, Switzerland, May 22, 2025 –WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company, today announces that its subsidiary SEALCOIN AG, developing a decentralized platform powering secure, autonomous, real-time transactions between IoT devices, unveils a series of major milestones as it accelerates toward its upcoming token launch this summer.

Following months of development and testing, SEALCOIN AG has released the latest version of its WhitePaper, which includes an upgraded tokenomics model to better align with long-term network incentives and security. This refined structure enhances both utility and governance for the upcoming TIOT token, ensuring sustainable growth and increased value for all stakeholders.

In parallel, the Minimum Viable Product (MVP) of the SEALCOIN platform has been officially launched. Fully integrated with Hedera’s public DLT infrastructure, the platform has entered its beta testing phase, with selected users onboarding to trial real-time, peer-to-peer device transactions.

Building on the success of its first technical Proof-of-Concept (PoC) in July 2024, SEALCOIN has reached a new milestone: a successful device-to-device transaction over satellite, completed in April 2025 in collaboration with WISeSat. This achievement proves SEALCOIN’s capability to execute secure microtransactions between remote IoT devices, even without terrestrial connectivity, marking a pivotal leap for decentralized infrastructure in off-grid environments.

Key Use Cases Gaining Traction Include:

• Energy Trading: allows smart meters to autonomously buy and sell energy between peers.
• Device-as-a-Service (DaaS): enables hardware to monetize excess computing resources like CPU or GPU.
• Smart Home Automation: facilitates direct value exchange between household devices.
• Data Marketplace: creates a framework where verified, high-value IoT data can be exchanged securely and transparently.

With these foundational achievements now in place, SEALCOIN is excited to announce the launch of its global marketing campaign as it enters the final stretch toward its public token launch.
