Our business

XAIN's specializes in cybersecurity, blockchain technology and machine learning solutions for enterprise clients.

Open Development

Developments to the XAIN protocol are overseen by our foundation, which is accountable to the public, research partners and enterprise stakeholders. We thus keep our protocol open source, meaning that anyone can openly access and verify the code. We believe that information transparency is paramount and strive to provide complete documentation for our users and clients. This includes a wiki, research papers and developer resources.


We believe in a solutions-oriented approach to development; that’s why we work closely with our industry clients and research partners to develop software integrations and innovative functionalities with real-world applications. We work closely with our clients from proof of concept phase to enterprise scale roll-outs.

User-Centric Approach

We adopt a user-centric approach to software development. That’s why our protocol is designed to place the user in full control of their data, thus enabling user-specific access control schemes and the individualization of privacy settings in IoT networks. Our approach allows enterprises to comply with privacy regulations and enhance customer trust through greater transparency.
