SEALCOIN AG, a subsidiary of WISeKey focused on decentralized physical infrastructure, has secured a $4 million strategic investment commitment to accelerate the blockchain transaction layer. The round includes a $1 million commitment from Hashgraph Group (THG) and a $3 million commitment from WISeKey International Holding, with the goal of integrating the SEALCOIN ecosystem more deeply into the emerging space economy.
The newly committed capital will fund the continued development of the SEALCOIN platform, powered by QAIT, a token issued by the QAIT Association and designed for machine-to-machine and space-related blockchain transactions. SEALCOIN seeks to integrate satellite communications, blockchain, digital identity, cybersecurity and IoT infrastructure into a unified framework for secure and autonomous automated interactions across satellite networks and terrestrial endpoints.
The ecosystem’s goals are use cases such as satellite-to-device transactions, autonomous automated payments, space-based IoT connectivity, digital asset settlement via satellite links, and DePIN-powered transportation and logistics systems. The financing is expected to deepen the integration between the WISeSat satellite constellation, the secure semiconductor technology SEALSQ, the decentralized identity infrastructure, and the QAIT-based transaction layer. “Space infrastructure has become an essential layer of the global digital economy,” said Carlos Moreira, Founder and CEO of WISeKey and SEALCOIN.
This investment comes on the heels of SEALCOIN’s SPACEDROP campaign, where more than 45,000 participants interacted with 19 operational WISeSat satellites to validate satellite-to-blockchain communications and user engagement flows. “Our community is becoming the first generation of space economy users,” according to Moreira, helping to test connectivity and services that support future machine-to-machine and space transactions on the network.
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 Hashgraph Group, we believe the next frontier of the decentralized economy isn’t just proxy — it’s orbital,” said Stefan Diess, co-founder and CEO of Hashgraph Group, noting that SEALCOIN on Hedera aims to use QAIT to settle autonomous machine transactions in space and between space and Earth. As the commercialization of satellite infrastructure accelerates and attention shifts toward orbital services and transaction layers, SEALCOIN is positioning itself as a key economic railway to the space machinery economy.
