WISeKey’s SEALCOIN Platform Confirms Integration of QAIT Token Following Market Launch

Geneva, Switzerland – May 29, 2026 – WISeKey International Holding Ltd. (NASDAQ: WKEY), through its SEALCOIN platform, today confirmed that the QAIT token, launched by the independent QAIT Association, will serve as the utility token utilized within the SEALCOIN ecosystem.

The QAIT token became available for trading on major cryptocurrency exchanges, including Binance, KuCoin, Gate.io, and MEXC, on May 28, 2026.

SEALCOIN is designed to enable trusted, autonomous machine-to-machine (M2M) transactions, allowing connected devices to securely identify, authenticate, and transact with one another without human intervention. Through the use of decentralized trust technologies, digital identities, and secure transaction protocols, the platform supports the development of a scalable and certifiable machine economy.

The integration of QAIT into the SEALCOIN platform supports a broad range of emerging use cases across industries, including smart cities, industrial IoT, connected vehicles, robotics, healthcare devices, energy infrastructure, logistics, and satellite communications.

As the Physical Internet evolves, billions of connected devices will increasingly require the ability to exchange value and services autonomously. SEALCOIN provides the infrastructure to facilitate these interactions through secure digital identities, trusted transaction validation, and post-quantum cybersecurity technologies developed by the WISeKey group.

Potential applications include autonomous vehicles paying charging stations directly, industrial equipment procuring services automatically, medical devices securely exchanging authorized data, logistics networks coordinating resources dynamically, and connected infrastructure optimizing energy consumption in real time.

The QAIT token is issued and governed independently by the Switzerland-based QAIT Association, which is responsible for the token economy and governance framework. SEALCOIN serves as the technology platform that utilizes the token for transaction-related functions within its ecosystem.

Carlos Moreira, Founder and CEO of WISeKey, noted, “The launch of QAIT is an important milestone for the trusted digital infrastructure being developed across the WISeKey Group. By combining cybersecurity, post-quantum semiconductors, satellite connectivity, and machine-to-machine transactions, we are building the foundations for a secure and autonomous digital economy.”

Jonathan LLamas, Chief Product & Strategy Officer of SEALCOIN added, “QAIT brings an economic layer to the SEALCOIN ecosystem, enabling devices to securely exchange value, services, and data autonomously. This is a key step toward making machine-to-machine commerce practical and scalable across real-world industries.”
