SEALSQ and SEALCOIN AG Unite to Future-Proof AI Agents with Post-Quantum Security

Geneva, Switzerland, Oct. 01, 2025 (GLOBE NEWSWIRE) --   

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced a breakthrough initiative with SEALCOIN AG (SEALCOIN), which focuses on decentralized physical internet with DePIN technology and house the development of the SEALCOIN platform and a subsidiary of SEALSQ’s parent company WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), to protect Artificial Intelligence (AI) agents from the looming threats posed by quantum computing. Building on its pioneering expertise in Post-Quantum Cryptography (PQC) and trusted semiconductor technologies, SEALSQ is introducing a new suite of solutions designed to safeguard AI operations and decision-making processes against adversarial quantum attacks.



Today’s cryptographic systems are under threat from the rise of quantum computing. Even the most secure digital identities and transactions risk becoming vulnerable. To address this, SEALCOIN AG is embedding quantum-resistant cryptography into every layer of its agent infrastructure, from identity certificates and wallet authorizations to smart contract execution. In partnership with SEALSQ, and leveraging the upcoming QS7001 secure element, this collaboration future-proofs AI Agents from the ground up. SEALSQ’s post-quantum secure AI framework integrates NIST-recommended PQC algorithms with its secure element chips and embedded cryptographic modules, ensuring confidential inference through homomorphic encryption optimized for SEALSQ hardware, robust identity and authentication with post-quantum digital identities, trusted execution environments that defend against both classical and quantum-level attacks, and scalable deployment across IoT, autonomous vehicles, smart infrastructure, defense, and healthcare.

“AI is only as trustworthy as the systems that protect it,” said Carlos Moreira, CEO of SEALSQ. “With this launch, SEALSQ provides the missing link between artificial intelligence and post-quantum cybersecurity, ensuring that AI agents remain reliable partners for humanity, even in the quantum era.”

This announcement coincides with the release of Episode 6 in SEALCOIN AG’s educational video series on Secure AI Agents, titled “Future-Proofing with Post-Quantum Security.” The series explores foundational principles of secure agent autonomy, including cryptographic identity, trusted transactions, decentralized execution, and now, quantum-resilient infrastructure ().

Over the past six episodes, SEALCOIN AG’s Secure AI Agent series has charted the journey from principle to practice for truly autonomous and trustworthy AI Agents. Starting with the foundation that autonomy without security is an illusion, the series explored why AI Agents need cryptographic identity and verifiable transactions to prevent spoofing and manipulation. It then showcased the core infrastructure SEALCOIN provides, verifiable certificates, controlled wallets, smart contracts, and immutable records, and illustrated how these elements come together in real-world agent-to-API interactions to enable secure, end-to-end autonomy. The series highlighted the transformative impact of this architecture, opening the door to new business models like autonomous procurement, AI-driven commerce, and machine-to-machine markets, before concluding with how SEALCOIN AG and SEALSQ are future-proofing agents with post-quantum security to ensure their trust and autonomy endure well into the quantum era.

Clarifying SEALCOIN AG’s Role: Enabling AI Infrastructure, Not AI Solutions

As enthusiasm around artificial intelligence continues to surge, SEALCOIN AG takes a transparent stance. We are not developing AI models or selling AI-based solutions, our focus is on delivering the underlying infrastructure that empowers AI Agents to operate securely and autonomously.

Our technology provides the essential building blocks: verifiable identity, cryptographic wallets, decentralized execution, and post-quantum resilience. It’s the digital equivalent of supplying shovels to gold miners, empowering developers, platforms, and enterprises to build meaningful AI use cases on trusted foundations. This sets SEALCOIN apart by grounding our value in verifiable, enabling technology.
