SEALSQ Corp. has taken a big leap in safeguarding the future of blockchain and digital payment ecosystems by implementing post-quantum cryptography (PQC) not only in the hardware but also in the protocol layers. With quantum computing gradually becoming capable of performing tasks in the real world, the company is mainly intent on creating crypto-agile infrastructures that can resist threats from quantum computing to the current encryption systems.
Although these quantum computers are still in their infancy, the threat of their capability to break many of the most popular cryptographic schemes in use today, such as RSA and elliptic curve encryption, is causing many in the business to worry. SEALSQ is taking a much longer-term approach to this problem and is therefore including quantum-resistant algorithms that have been suggested by the US National Institute of Standards and Technology (NIST), namely CRYSTALS-Kyber for quantum-resistant key exchanges and CRYSTALS-Dilithium for quantum-resistant digital signatures.
The algorithms are being integrated into secure hardware components such as trusted platform modules and secure elements to provide secure key generation, storage, and protection from being stolen or compromised. By using secure hardware to protect blockchain private keys, SEALSQ is hoping to provide stronger security for their customers from today’s cybersecurity threats as well as those of the future from quantum computing.
In addition to the secure hardware, SEALSQ is also improving the integrity of blockchain transactions through the use of PQC digital signatures.

The company is also collaborating with Swiss blockchain platform WeCan to apply these technologies in financial use cases. The integration leverages PQC, secure multiparty computation, zero-knowledge proof systems, and advanced consensus techniques to bring privacy, compliance, and resilience to distributed environments.
Further expanding on this, SEALSQ is developing an expansion of their security solution to machine-to-machine environments through the development of SEALCOIN.AI. This allows autonomous machines and AI agents to securely interact and transact with one another. This solution is applicable to a variety of verticals, such as energy, mobility, space communications, and more, facilitated by satellite communications through WISeSat.Space.
“Quantum computing represents both a challenge and an opportunity,” said Carlos Creus Moreira, Founder and CEO of SEALSQ. “By embedding post-quantum cryptography directly into semiconductors, blockchain protocols, and space-based infrastructure, we are taking a proactive approach to this shift, ensuring that trust in digital systems is not only preserved, but significantly strengthened. Our strategy is to integrate security at every layer of the technology stack, from hardware to decentralized networks, so that governments, enterprises, and critical industries can operate with confidence in the quantum era.”
SEALSQ uses a layered approach to lead in quantum-resilient security. This helps organizations protect their digital assets and transactions against a complex threat landscape.
