ZengoX is a research group composed of researchers from academia and industry.Our goal is to take threshold cryptography all the way from theory to your mobile device (or any consumer software/hardware). We combine deep knowledge in applied cryptography and distributed systems security to push forward the usage and limits of Multiparty Computation (MPC).

Research Grants

Cryptography, security and research is at the heart of what we do. Zengo^x has received research grants from some of the leading projects in the crypto world. In addition, we received an R&D grant from the Israel Innovation Authority. We are committed to working hand-in-hand with all the builders of digital assets in order to provide the best native support and experience.
