Open-source is one of the major concepts in the cryptocurrency space as the whole industry basically grew up on it. Nowadays, building a crypto project without publishing at least a part of your code on GitHub is considered to be bad manners.

We are proud to say that our core wallet technology is open-source. You can view the libraries (for Android and Web) that we use to generate private keys and sign the transactions. 

We use these libraries in our apps and in the web version of the wallet. You are welcome to see and review it anytime via this link.
