Our work

Our value lies in a strong technological background which allows us to
spread our know-how in blockchain further.

Strong member of Blockchain

Our team of blockchain engineers led by Josef Gattermayer, Ph.D., assistant professor at CTU, shares their expertise globally. Besides providing open-source solutions to the development community, we contribute to conferences like Devcon, where we also provided the official conference app.

Trusted by the Best

Assigned official development grants by three key blockchain foundations – Ethereum Foundation, Tezos Foundation and KIN Foundation.

Our open-source DevKits

Our mission to bring blockchain closer to developers is realised here.

We love that we made it possible to call Ethereum smart contracts directly from the Swift language. Since our open source release of the library and code generator, iOS developers can work with Ethereum smart contracts as with another SDK. 

Another contribution to the community we are proud of was made with our PoC app using Tezos DevKit with step-by-step tutorials of how to use its TezosSwift library. 

Executive team

With years of experience under our belt, we are ready for any challenge.
