WISeKey's SEALCOIN Subsidiary Accelerates Space-Based Blockchain Infrastructure Following Strategic $4 Million Investment Commitment
New Funding from The Hashgraph Group and WISeKey Supports Expansion of the QAIT-Powered Space Economy and Next-Generation Satellite Transactions
Geneva, Switzerland --June 10, 2026 -- WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY), a global leader in cybersecurity, digital identity and IoT, today announced that its subsidiary SEALCOIN which focuses on decentralized physical internet with DePIN technology and houses the development of the SEALCOIN platform secured $4 million strategic investment, including a $1 million commitment from The Hashgraph Group (THG) and a $3 million commitment from WISeKey, with the objective to accelerate the integration of the SEALCOIN ecosystem into the rapidly emerging space economy.
The investment comes at a time when global attention is increasingly focused on the commercialization of space infrastructure. As discussions surrounding the anticipated SpaceX IPO continue to highlight the growing economic significance of satellite networks and space-based services, SEALCOIN is advancing a complementary vision: creating the blockchain-powered transaction layer that enables machines, devices, satellites, and autonomous systems to securely exchange data, services, and value.
The newly committed capital is intended to support the planned continued development of the SEALCOIN ecosystem, powered by QAIT, issued by the QAIT Association, the dedicated utility token designed for machine-to-machine and space-related blockchain transactions.
"Space infrastructure is becoming a foundational layer of the global digital economy," said Carlos Moreira, Founder and CEO of WISeKey and SEALCOIN. "As satellites increasingly connect machines, sensors, autonomous vehicles, and critical infrastructure worldwide, there is a growing need for trusted digital identities, secure settlement mechanisms, and autonomous transaction capabilities. The SEALCOIN platform has been created to capture this opportunity and enable value creation across this new layer."
Building the Economic Layer for the Space Economy
SEALCOIN aims to combine satellite communications, blockchain technology, digital identity, cybersecurity, and Internet of Things (IoT) infrastructure to create a trusted framework for autonomous machine interactions.
The ecosystem is designed to support a broad range of emerging use cases, including:
-- Satellite-to-device transactions -- Autonomous machine payments -- Space-based IoT connectivity -- Digital asset settlement across satellite networks -- Trusted location and telemetry services -- Decentralized infrastructure applications (DePIN) -- Autonomous logistics and mobility systems
The additional funding is expected to further strengthen integration between the WISeSat satellite constellation, secure SEALSQ semiconductor technology, decentralized identity infrastructure, and the transaction layer, facilitated by the adoption of the QAIT Association's token.
Celebrating the Success of SPACEDROP and the First Community of Space Economy Pioneers
SEALCOIN also took the opportunity to recognize the thousands of participants who joined the recently completed SPACEDROP campaign.
Over several weeks, more than 45,000 participants interacted directly with the WISeSat satellite constellation (another subsidiary of WISeKey, focused on space technology for secure satellite communication, specifically for IoT applications) engaging with all 19 operational satellites and helping validate real-world satellite-to-blockchain communications, infrastructure performance, and user engagement mechanisms.
What began as a community campaign evolved into one of the first large-scale public demonstrations of a blockchain-enabled space infrastructure network. WISeKey appreciates the support it has received from these early adopters, whose participation helped test and strengthen critical components of the ecosystem.
"Our community became our first generation of space economy users," said Mr. Moreira. "By interacting with the constellation, validating connectivity, and actively engaging with our infrastructure, they contributed directly to the development of services that will support future machine-to-machine and space-based transactions."
From Space Infrastructure to Space Commerce
The commercial space industry is entering a new phase.
While satellites and launch systems have traditionally captured the spotlight, attention is increasingly shifting toward the digital services and economic systems that will operate on top of this infrastructure.
"The growing excitement around the commercial space economy confirms what we've believed from the beginning: connectivity alone is not enough. The future requires a trusted economic layer that enables machines, satellites, sensors, and autonomous systems to transact securely and autonomously. With the support of WISeKey, The Hashgraph Group, and our global community, we are accelerating the deployment of that vision through SEALCOIN and its Machine Economy," said Jonathan LLamas, Chief Product & Strategy Officer at SEALCOIN AG.
With strategic support from WISeKey and The Hashgraph Group, the continued expansion of the WISeSat constellation, the launch of the QAIT utility token by the QAIT Association, and an engaged global community of early adopters, SEALCOIN is positioning itself to become a key transaction layer for the future space economy.
"At The Hashgraph Group, we believe the next frontier for the decentralized economy isn't just agentic -- it's orbital. The autonomous space economy is the next trillion-dollar frontier, and we are actively building the trust infrastructure with SEALCOIN on Hedera, leveraging QAIT to settle secure autonomous machine-to-machine transactions in space and between space and Earth at the speed of light, while unlocking a new market with no terrestrial ceiling." Stefan Deiss, Co-Founder & CEO of The Hashgraph Group.
As space connectivity becomes increasingly integrated into everyday infrastructure, SEALCOIN's mission remains clear: enabling trusted digital identities, secure autonomous transactions, and machine-driven economic activity across Earth and beyond.
