Bitcoin Cash builder community

Build. Learn. Collaborate.

Training and exploring the peer-to-peer electronic cash ecosystem with developers, students, designers, and entrepreneurs.

A structured space to build on Bitcoin Cash.

BCH Builders Lab is an evolution of the BCH Builders Meetup. Through meetups, build sessions, hackathons, and community collaborations, we're creating a consistent environment where developers can learn what's possible with BCH and turn that knowledge into working applications.

Build

Hands-on experimentation.

Prototypes, integrations, and open-source projects shipped, not just discussed.

Learn

Explore what's possible.

BCH infrastructure, developer tools, APIs, SDKs, and emerging technologies mapped and demystified.

Collaborate

Meet the builders.

Developers, contributors, and ecosystem projects across Nigeria, Africa, and beyond.
