Bitcoin Dev Kit

Abiodun is a software engineer and Bitcoin open-source contributor based in Lagos, Nigeria. His work focuses on wallet infrastructure in the @bitcoindevkit ecosystem. @_abiodunAwoyemi is a secondary maintainer of bdk-tx, a transaction-building library in the BDK ecosystem. His contributions have covered many areas that directly affect wallet safety and reliability. These include fee calculation fixes, anti-fee-sniping support, Payjoin examples, CPFP fee-bumping support, locktime handling, BIP353 payment support reviews, PSBT creation, BIP322 message signing, and continuous integration improvements. With the long-term grant, Abiodun will continue strengthening BDK and BDK-TX. His work will focus on making Bitcoin transaction construction safer, more predictable, and easier for developers to use. Abiodun also co-organizes @BitDevsLagos 🇳🇬, helping create space for technical Bitcoin discussion and contributor growth in Nigeria.

BDK (@bitcoindevkit) contributor Thunderbiscuit (@thunderB__) is now on stage at @btcplusplus Consensus Edition talking about Compact Block Filters for users and wallet devs!

Nice repo from @thunderB__ that will download all compact block filters (be careful doing this on mainnet because it will be 12GB!) and store them in a db so you can run queries and analyze the data h/t @btcplusplus Toronto github.com/thunderbiscuit…

Today, we wrapped up the week 5 study group session of the Bitcoin CLI live cohort. ⚡ This week, participants took a deeper dive into Bitcoin Script by exploring Pay-to-Script-Hash (P2SH) transactions and script-based timelocks. The cohort learned how P2SH makes it possible to embed more complex spending conditions into Bitcoin transactions, including multisignature and SegWit scripts. They also explored how timelock opcodes like CheckLockTimeVerify (CLTV) and CheckSequenceVerify (CSV) can be used to control when bitcoin can be spent, enabling more advanced and flexible transaction workflows. Through hands-on technical exercises, partner discussions, and collaborative learning, participants gained practical experience writing and working with these more advanced Bitcoin scripting features.

Async payjoin sessions are now persisted to SQLite, so interrupted payjoin sessions can be resumed. The release also includes internal refactoring that improves readability and makes adding new commands easier and less prone to errors and updates the Wallet API to v3.1.0. 🚀

This release introduces experimental support for creating silent payment transactions and adds support for BIP-353 DNS payment instructions. It also adds UTXO locking through new wallet commands.

📢 Version 4.0.0 of BDK CLI has been released! Massive thanks to all the contributors that made this release possible and especially to @tvpeter for being the bdk-cli maintainer and delivering this milestone. github.com/bitcoindevkit/…

Too few people understand the bdk_chain crate deeply, so @_oleonardolima hosted a deep dive at Casa21 with our fellows and grantees. We went through how @bitcoindevkit models chain data, transaction graphs, anchors, checkpoints, spks, seen-at timestamps, and the indexing logic that lets wallets reason about transactions without depending on a single backend. These sessions are part of our monthly in-person technical deep dives, where we fly Vinteum fellows and grantees to São Paulo for a week of focused work: reading specs, reviewing PRs, studying architectures, finding bugs, and contributing together. In-person protocol work is powerful.

📣 BDK Wallet 3.1.0 was released this month! github.com/bitcoindevkit/… 3.1.0 introduces new ways to have even more control over the signing process, as well as bug fixes and improvements.

Love to see Peach using our latest and coolest libraries! github.com/bitcoindevkit/…

Cross-platform bitcoin wallets are becoming easier to build with Flutter and bdk-dart. In this talk, @john_osezele showed how developers can build Bitcoin apps for iOS and Android using the @bitcoindevkit's Dart bindings, using a reference wallet to demonstrate core functionality. A highlight shared is that bdk-dart is currently integrated with the @BULLBITCOIN_ mobile wallet.

NEW major versions of BDK Bindings are released! They use BDK 3.0 under the hood, and we have mobile users covered across even more languages too with BRAND NEW bindings for React Native and Dart/Flutter. github.com/bitcoindevkit/…

The BDK Foundation is happy to announce two new corporate members for Q2 2026 - @SatoshiPacioli and @mempool ! A big thanks to our new and continuing members @spiralbtc, @OpenSats, @AnchorWatch, @CleanSpark_Inc, and @ProtonPrivacy for their support. bitcoindevkit.org/blog/2026_q2_n…

Meet Loupe, an AI-powered vulnerability scanner for open-source bitcoin projects. Attackers already use AI to find weaknesses. Maintainers should do the same. Bitcoin Core, BDK, LDK, rust-bitcoin, Cashu, Jade, bitcoinj, and SRI are already onboard. spiralbtc.substack.com/p/meet-loupe-a…

@spiralbtc A thing of beauty should always get a closer look :-)

📣 BDK Wallet 2.4 was released today! This release focuses on back porting migration support and event system enhancements from the 3.0 release. For those not ready to move to 3.0 see what's new in 2.4 here: github.com/bitcoindevkit/…

📣 BDK Wallet 3.0 was released two weeks ago but forgot to announce it, so here you go! See all the details here: github.com/bitcoindevkit/…
