What should I expect working here?
You will be challenged and always learning. This project spans concepts of distributed systems, heavy-duty cryptography, UI/UX challenges of simplifying complex information, cross-chain communication, and much more.

You will be encouraged to think about world economies and what it takes to build a universal privacy layer for all crypto assets. You will build tools to bring equality to the global economy so that everyone has access to complete financial sovereignty.

We value kindness, curiosity, and the willingness to learn and to teach. 😊
