Although there is *some* code to handle multipath keys inside bdk,
it's all untested, and from a few quick tests it
seems that it's pretty easy to find buggy edge cases.
Better to deny multipath descs for now, and revisit the
decision once we work on supporting multidescriptor wallets.

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 the bdk_core_staging repo where a lot of the component work is being done. The plan is that everything in the bdk_core_staging repo will be moved into the crates directory here.

Architecture

The project is split up into several crates in the /crates directory:

bdk: Contains the central high level Wallet type that is built from the low-level mechanisms provided by the other components
chain: Tools for storing and indexing chain data
file_store: A (experimental) persistence backend for storing chain data in a single file.
esplora: Extends the esplora-client crate with methods to fetch chain data from an esplora HTTP server in the form that [bdk_chain] and Wallet can consume.
electrum: Extends the electrum-client crate with methods to fetch chain data from an electrum server in the form that [bdk_chain] and Wallet can consume.

Fully working examples of how to use these components are in /example-crates

Minimum Supported Rust Version (MSRV)

This library should compile with any combination of features with Rust 1.57.0.

To build with the MSRV you will need to pin dependencies as follows:

# log 0.4.19 has MSRV 1.60.0+
cargo update -p log --precise "0.4.18"
# tempfile 3.7.0 has MSRV 1.63.0
cargo update -p tempfile --precise "3.6.0"
