The Bitcoin Dev Kit
BDK

A modern, lightweight, descriptor-based wallet library written in Rust!
Project Homepage | Documentation
About
The bdk
libraries aims to provide well engineered and reviewed components for Bitcoin based applications.
It is built upon the excellent rust-bitcoin
and rust-miniscript
crates.
⚠ The Bitcoin Dev Kit developers are in the process of releasing a
v1.0
which is a fundamental re-write of how the library works. See for some background on this project: https://bitcoindevkit.org/blog/road-to-bdk-1/ (ignore the timeline 😁) For a release timeline see theBDK 1.0 project page
.
Architecture
The project is split up into several crates in the /crates
directory:
wallet
: Contains the central high levelWallet
type that is built from the low-level mechanisms provided by the other componentschain
: Tools for storing and indexing chain datapersist
: Types that define data persistence of a BDK walletfile_store
: A (experimental) persistence backend for storing chain data in a single file.esplora
: Extends theesplora-client
crate with methods to fetch chain data from an esplora HTTP server in the form thatbdk_chain
andWallet
can consume.electrum
: Extends theelectrum-client
crate with methods to fetch chain data from an electrum server in the form thatbdk_chain
andWallet
can consume.
Fully working examples of how to use these components are in /example-crates
:
example_cli
: Library used by theexample_*
crates. Provides utilities for syncing, showing the balance, generating addresses and creating transactions without using the bdk_walletWallet
.example_electrum
: A command line Bitcoin wallet application built on top ofexample_cli
and theelectrum
crate. It shows the power of the bdk tools (chain
+file_store
+electrum
), without depending on the mainbdk_wallet
library.example_esplora
: A command line Bitcoin wallet application built on top ofexample_cli
and theesplora
crate. It shows the power of the bdk tools (chain
+file_store
+esplora
), without depending on the mainbdk_wallet
library.example_bitcoind_rpc_polling
: A command line Bitcoin wallet application built on top ofexample_cli
and thebitcoind_rpc
crate. It shows the power of the bdk tools (chain
+file_store
+bitcoind_rpc
), without depending on the mainbdk_wallet
library.wallet_esplora_blocking
: Uses theWallet
to sync and spend using the Esplora blocking interface.wallet_esplora_async
: Uses theWallet
to sync and spend using the Esplora asynchronous interface.wallet_electrum
: Uses theWallet
to sync and spend using Electrum.
Minimum Supported Rust Version (MSRV)
This library should compile with any combination of features with Rust 1.63.0.
To build with the MSRV you will need to pin dependencies as follows:
cargo update -p zstd-sys --precise "2.0.8+zstd.1.5.5"
cargo update -p time --precise "0.3.20"
cargo update -p home --precise "0.5.5"
cargo update -p proptest --precise "1.2.0"
