Isaack Njama, software engineer at @Minmo will lead a hands-on workshop at the #BtrustDeveloperDay. In this session, participants will discover just how quickly they can create a Tando-like bitcoin off-ramp experience using the Minmo API. Isaack will guide developers through the full process, from setting up a user and an agent, creating API keys with the right permissions, and designing a simple interface that can initiate off-ramp swaps, to understanding the escrow, settlement, and dispute tracking systems that support Minmo’s infrastructure. By the end of the workshop, attendees will have built their own functioning micro-offramp with a custom UI, connected to Minmo’s agent network and escrow system. With over four years of experience building reliable systems in TypeScript and Rust, Isaack brings deep technical expertise and a passion for community-driven development. At Minmo, he develops open-source tools that support grassroots Bitcoin adoption, and his contributions to Fedimint have advanced secure custody solutions for communities around the world. As an engineering fellow at Btrust Builders and a co-organizer of BitDevs Nairobi 🇰🇪, he works to grow the local Bitcoin developer community while making the Lightning Network and Bitcoin protocols accessible through clear, practical education. His commitment to sharing knowledge through technical writing and collaborative development ensures that his work not only builds tools, but also expands financial freedom and strengthens decentralized systems. 👉 RSVP today to secure your spot:
