There are a lot of developers opening PRs. But who’s reviewing them? 👀 If you’re looking to contribute to open source without writing code, head over to Pull Reviews. Find a PR from another builder, take a look, leave useful feedback, and help move the project forward. Your next contribution might just be a review. 👉 pullos.dev/pr-reviews

Abraham (@abeeujah) is a developer based in Nigeria 🇳🇬, whose Bitcoin open-source journey began through @BitDevsKaduna. He built his knowledge through @ChaincodeLabs’ protocol development seminars, the @FreeRoutingAf Kaduna Lightning Developer Bootcamp, and Bitcoin Core Principles by @libdesatoshi. He also completed the 2026 BOSS Challenge and was featured by @btrust_builders as one of eleven African participants whose journeys stood out. With the starter grant, Abraham will focus on testing, protocol libraries, and developer tooling across rust-bitcoin and rust-lightning, strengthening the building blocks developers use for Bitcoin and Lightning applications.

Their work, alongside that of recipients in Nigeria 🇳🇬 and Kenya 🇰🇪, spans @bitcoincoreorg, mining ⛏️ infrastructure, Lightning⚡, wallet libraries, and privacy-preserving payments. Meet the recipients and learn about their work:

Two ways to convert your Bitcoin on Lightning with Tapnob: 1. Create an invoice on Tapnob → pay it from any Lightning wallet → your linked bank account gets credited. 2. Use your Tapnob Lightning Address → send sats to your address → they’re automatically converted and settled to your linked bank account. Which is your favorite?

From understanding Lightning to making it work. ⚡ Sessions 13 & 14 of Rust for Bitcoin 2.0 took participants deeper into the Lightning Network and its role within the Bitcoin ecosystem. With @200OKDeveloper, @megasley and @damola21mm guiding the sessions, participants explored key Lightning concepts and worked hands on with Polar, LNURL, and LUD-05, moving from understanding the technology to interacting with it in practice. The sessions also featured practical Lightning transactions, giving participants direct experience with sending and receiving Lightning payments and a clearer understanding of how Lightning based applications work. Two sessions of practical learning that brought participants closer to the program’s bigger goal: moving from learning Bitcoin technologies to building and contributing to the Bitcoin ecosystem. #TheBuidlGrid #RustForBitcoin

Yes, @hack4_freedom is free to participate. 🎉 Your workshop and event costs are covered, so you can focus on what really matters: learning, building and contributing. But this is a developer-focused programme. Hack4Freedom is for women developers in Kenya with a technical foundation who are curious about Bitcoin, Lightning, Nostr, eCash and open-source development. You’ll learn from experienced contributors and educators, get hands-on with the technology, collaborate with other developers and put your skills to work during the hackathon. So, if you’re a developer looking to deepen your technical knowledge and explore freedom technologies, this opportunity is for you. 📅 Sept. 22 – Oct. 5, 2026 📍 Nairobi, Kenya Apply here: app.evento.so/e/evt_thLRxQBL… #Hack4Freedom #DadaDevs #BitcoinDevelopment
