WISeKey’s SEALCOIN raises $4M from WISeKey and Hashgraph to build space-based DePIN layer

SEALCOIN AG, the WISeKey subsidiary focused on decentralized physical infrastructure, has secured a $4 million strategic investment commitment to accelerate its space-based blockchain transaction layer. The round includes a $1 million commitment from The Hashgraph Group (THG) and a $3 million commitment from WISeKey International Holding, aimed at integrating the SEALCOIN ecosystem more deeply into the emerging space economy.

The newly committed capital will fund continued development of the SEALCOIN platform, which is powered by QAIT, a utility token issued by the QAIT Association and designed for machine-to-machine and space-related blockchain transactions. SEALCOIN seeks to fuse satellite communications, blockchain, digital identity, cybersecurity, and IoT infrastructure into a unified framework for secure, autonomous machine interactions across satellite networks and terrestrial endpoints.

The ecosystem targets use cases such as satellite-to-device transactions, autonomous machine payments, space-based IoT connectivity, digital asset settlement over satellite links, and DePIN-powered logistics and mobility systems. The funding is expected to deepen integration between the WISeSat satellite constellation, SEALSQ secure semiconductor tech, decentralized identity infrastructure, and the QAIT-based transaction layer. “Space infrastructure is becoming a foundational layer of the global digital economy,” said Carlos Moreira, Founder and CEO of WISeKey and SEALCOIN.

The investment follows SEALCOIN’s SPACEDROP campaign, where more than 45,000 participants interacted with WISeSat’s 19 operational satellites to validate satellite-to-blockchain communications and user engagement flows. According to Moreira, “Our community became our first generation of space economy users,” helping to test connectivity and services that underpin future machine-to-machine and space-based transactions on the network.

The Hashgraph Group, which operates within the Hedera ecosystem, positions the deal as a bet on orbital infrastructure as the next phase of the decentralized economy. “At The Hashgraph Group, we believe the next frontier for the decentralized economy isn't just agentic – it's orbital,” said Stefan Deiss, Co-Founder & CEO of The Hashgraph Group, noting that SEALCOIN on Hedera aims to use QAIT to settle autonomous machine transactions in space and between space and Earth. As commercialization of satellite infrastructure accelerates and attention shifts toward on-orbit services and transaction layers, SEALCOIN is positioning itself as a key economic rail for the space-based machine economy.
