WISeSat.Space announced at Paris Space Week the Launch this fourth quarter with a World First: SEALCOIN Exchange from Space Opening the Way for Blockchain Transactions in Orbit
MWN-AI** Summary
WISeKey International Holding Ltd has made a groundbreaking announcement during Paris Space Week, revealing the impending launch of its Low Earth Orbit (LEO) satellite in the fourth quarter of 2025. This satellite will facilitate the first-ever satellite-enabled blockchain transaction using SEALCOIN, a significant advancement in decentralized IoT ecosystems.
The initiative aims to revolutionize how value exchanges occur in environments lacking terrestrial infrastructure. By integrating satellite communications with IoT technology, SEALCOIN enables secure microtransactions directly from off-grid devices. The process begins with an IoT device initiating a transaction, which is cryptographically signed for authenticity. The transaction is then transmitted via the WISeSat satellite constellation to a second device connected to a terrestrial network, where it is validated and recorded on the Hedera blockchain. This streamlined method ensures secure and efficient machine-to-machine exchanges, with potential applications in sectors such as smart agriculture and autonomous logistics.
The launch is just the first phase of SEALCOIN's ambitious roadmap towards a “Satellite-as-a-Service” model. Future developments will incorporate SEALCOIN technology directly at the silicon level within satellites, enhancing autonomous space infrastructure that participates in decentralized digital economies. WISeKey’s CEO, Carlos Moreira, emphasized the importance of this launch, describing it as a significant step towards a borderless and secure IoT economy.
WISeKey’s commitment to advancing technology at the crossroads of cybersecurity, blockchain, IoT, and space sets the stage for substantial future applications. With the upcoming satellite launch, WISeKey aims to strengthen its leadership and create a more resilient global IoT economy, extending reach and enhancing connectivity in even the most remote locations.

WISeSat.Space announced at Paris Space Week the Launch this fourth quarter with a World First: SEALCOIN Exchange from Space Opening the Way for Blockchain Transactions in Orbit.
Geneva, Switzerland and Paris, France September 16 , 2025 – WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company, today announced that its subsidiary SEALCOIN AG will achieve a historic milestone in late-2025 with the launch of a new WISeSat Low Earth Orbit (LEO) satellite supporting the first-ever satellite-enabled blockchain transaction using SEALCOIN.
SEALCOIN Demonstrates Satellite-Enabled IoT Transactions Using WISeSat LEO Constellation
Pushing the Frontiers of TIoT with Secure, Decentralized Microtransactions Beyond Terrestrial Limits
This breakthrough marks a world first: the ability to conduct a secure value exchange directly from space, enabling a new era of decentralized IoT economies that extend beyond terrestrial infrastructure.
Building on a recently unveiled Proof of Concept (PoC), SEALCOIN has successfully demonstrated the integration of blockchain-based value exchange with IoT devices through satellite communications. By leveraging the WISeSat LEO constellation and the FOSSA IoT platform, SEALCOIN enables microtransaction-driven data exchanges between fully off-the-grid IoT devices, each cryptographically signed at the source to guarantee integrity and trust.
How it Works
- Off-Grid Device Initiates the Transaction
A remote IoT device without terrestrial connectivity creates a blockchain transaction, signing it securely inside its onboard Secure Element to ensure authenticity and integrity. - Satellite Relay to a Connected Peer
The signed transaction is sent via the WISeSat constellation to a second IoT device with terrestrial network access. - Verification and Blockchain Execution
The receiving device validates the transaction and submits it directly to the Hedera network for settlement, acting as a trusted bridge between the off-grid device and the blockchain. - Data Returned Through Space
Once the transaction is confirmed on-chain, the second device transmits the requested data back to the originating off-grid device via satellite, completing the secure, autonomous machine-to-machine exchange.
This first-of-its-kind demonstration proves the feasibility of secure, decentralized, satellite-enabled data transactions between machines in remote or infrastructure-deficient regions. Potential applications span smart agriculture, environmental monitoring, autonomous logistics, and defense systems—sectors where reliable connectivity is critical but often unavailable.
Roadmap: From Proof of Concept to “Satellite-as-a-Service”
The upcoming satellite launch represents Phase One of SEALCOIN’s space integration roadmap. Future iterations will embed SEALCOIN capabilities directly within satellites at the silicon level using Secure Element technology, creating a foundation for autonomous, spaceborne infrastructure that actively participates in decentralized digital economies.
“Our goal with SEALCOIN has always been to make transactional IoT borderless, scalable, and secure,” said Carlos Moreira, CEO of WISeKey Group. “With this milestone, we’ve expanded that vision into space, opening the door to solutions for regions with no cellular or terrestrial coverage. This launch sets the stage for a new economy—secure, decentralized, and space-enabled.”
Toward a Borderless, Resilient IoT Economy
SEALCOIN’s modular architecture supports a plug-and-play integration model, allowing interoperability with diverse sensors and satellite operators. This flexibility positions SEALCOIN as the backbone for a truly global, device-to-device IoT economy—resilient by design, autonomous in execution, and borderless in scope.
The upcoming launch will further strengthen WISeKey’s leadership at the intersection of cybersecurity, blockchain, IoT, and space technology. This next-generation satellite model will enhance the current constellation with advanced technological innovations, incorporating features such as:
This next-generation satellite model is designed to significantly enhance the capabilities of the current constellation through a series of advanced technological innovations.
