We're changing how people and companies thrive in the digital world.

Our Mission

In the future, every human and device will be able to protect their data flows (from chat messages to business contracts to digital money) while asserting identity when necessary. Banking will be contextual, available from the nearest device. Self-agency, self-sovereignty.

Our Values

We believe that every development team should be able to leverage the power of blockchain technology. We believe that companies and individuals should be able to protect their data and identities in the digital world. We believe that the balance between privacy and regulation / social stability lies in embracing self-sovereign, censorship-resistant identity for humans and for machines.
