Decentralizing Bitcoin development, Starting in Africa.

Btrust Builders (formerly Qala Africa) is Btrust's engineering training arm. We support developers through structured learning, mentorship, open-source contribution programs, and long-term opportunities.

Our goal is to help developers move from learning about Bitcoin to contributing to its software and infrastructure.

We start in Africa and work toward a more globally distributed Bitcoin contributor ecosystem.
