SEALCOIN develops infrastructure for the machine economy, leveraging Hedera network and post-quantum cryptographic expertise
Zug, Switzerland – April 22, 2026 — WISE KEY INTERNATIONAL HOLDINGS LIMITED (“WISeKey”) (SIX: WIHN, NASDAQ: key). “Space Drop”an early access onboarding initiative that allows users to interact directly with the SEALCOIN ecosystem before a wider rollout.
Unlike traditional Web3 airdrops designed to stimulate short-term speculation, Spacedrop is a structured onboarding experience focused on familiarizing participants with the real SEALCOIN infrastructure. Through a series of Soul-Bound Tasks, Points, and Tokens (SBTs), users can explore how identity, device logic, and decentralized settlement work within a live, satellite-connected environment.
Spacedrop provides an early demonstration of SEALCOIN’s machine-to-machine architecture, which combines hardware-based identity, certificate-based authentication, satellite connectivity, and Hedera’s decentralized ledger technology. The program is designed to build understanding and engagement with the platform’s core systems before any broader ecosystem or token expansion. This includes learning about the transaction layer of the network, where QAIT acts as the original settlement mechanism for interactions across devices and services.
SEALCOIN lies at the intersection of Hedera’s IoT, AI, and decentralized technology and is designed to enable secure and autonomous interactions between digital devices and services. It combines hardware-based identity, certificate-based authentication, and programmable settlement mechanisms to support real-world use cases across industries such as energy, telecommunications, mobility, and space infrastructure.
As part of the ecosystem, SEALCOIN offers QAIT as its native settlement token, designed to enable secure machine-to-machine transactions across devices, agents and services. QAIT supports core network functions such as transaction settlement, device setup (PoSy), and interactions within vertical markets, embedding the exchange of value directly into real-world infrastructure usage. Wider access to the ecosystem features and functionality powering the token will be activated gradually in connection with the upcoming network launch.
The installation of WSESAT satellites creates the first operational infrastructure within this market. Once certified and registered, satellites become independent economic actors able to price and settle services without human intervention. Participants can engage with satellite infrastructure on-chain, making the platform’s architecture tangible through interaction rather than theory. Satellites have already evolved beyond communication. Thanks to SEALCOIN’s built-in proxy capabilities, they can interact with the network and issue on-chain proofs (SBTs) directly to participants, along with game mechanics.
Spacedrop differentiates SEALCOIN from typical Web3 projects by shifting away from speculative airdrop models towards a real, structured, infrastructure-driven product built on satellite connectivity and secure device identity.
“Spacedrop reflects our commitment to building real infrastructure before market narratives,” he said. Carlos Moreira, Founder and CEO of WISeKey. “At SEALCOIN, we are not providing another token-based model, but rather a foundation for secure, autonomous interactions between devices on a global scale. By combining satellite connectivity with decentralized technologies and device-based identity, we are enabling a new machine economy where trust, security, and real-world usage come first. Spacedrop gives users an early and direct way to experience how this vision works in practice.”
A key differentiator of the ecosystem is its focus on hardware and protocol-level security, including post-quantum cryptography (PQC) developed in collaboration with SEALSQ and the broader WiseKey ecosystem. This approach enables devices to verify themselves and interact securely, even in environments where future quantum computing capabilities may challenge traditional cryptographic systems.
“Spacedrop is designed as a qualification layer in the SEALCOIN ecosystem, not as a reward mechanism,” he said. Jonathan Lamas, Chief Product and Strategy Officer at SEALCOIN. “We wanted users to experience how the network works, from identity to interaction flows, before any broader rollout. This approach allows us to build a community aligned with true adoption, integration, and long-term ecosystem development, rather than short-term incentives.”
Since launching in a closed environment, Spacedrop has quickly gained traction, with over 17,500 wallets registered within the first week. The campaign targets Web3 users, developers in DePIN, AI, and IoT, as well as enterprise and corporate observers evaluating next-generation infrastructure for autonomous systems.
Kamal Yousfi, President of the Hashgraph AssociationThe Swiss non-profit dedicated to accelerating the widespread adoption of the Hedera Network added, “We are excited about the progress SEALCOIN has made since our involvement in 2024 and with today’s Spacedrop announcement, where everyone can experience a new world of autonomous machine-to-machine transactions on Hedera as the core infrastructure of trust.”
Importantly, Points and SBTs earned through Spacedrop do not represent tokens, financial rights, or guaranteed future allocations. The initiative is positioned strictly as an engagement and education layer within SEALCOIN’s broader go-to-market strategy, which focuses on enterprise adoption, infrastructure deployment, and gradual ecosystem expansion. QAIT, as the ecosystem’s native utility token, is designed exclusively to support network operations.
