The Bitcoin Dev Kit

BDK

A modern, lightweight, descriptor-based wallet library written in Rust!

Crate InfoMIT or Apache-2.0 LicensedCI StatusAPI DocsRustc Version 1.63.0+Chat on Discord

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 1.0 project page.

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:

  • example_cli: Library used by the example_* crates. Provides utilities for syncing, showing the balance, generating addresses and creating transactions without using the bdk Wallet.
  • example_electrum: A command line Bitcoin wallet application built on top of example_cli and the electrum crate. It shows the power of the bdk tools (chain + file_store + electrum), without depending on the main bdk library.
  • example_esplora: A command line Bitcoin wallet application built on top of example_cli and the esplora crate. It shows the power of the bdk tools (chain + file_store + esplora), without depending on the main bdk library.
  • example_bitcoind_rpc_polling: A command line Bitcoin wallet application built on top of example_cli and the bitcoind_rpc crate. It shows the power of the bdk tools (chain + file_store + bitcoind_rpc), without depending on the main bdk library.
  • wallet_esplora_blocking: Uses the Wallet to sync and spend using the Esplora blocking interface.
  • wallet_esplora_async: Uses the Wallet to sync and spend using the Esplora asynchronous interface.
  • wallet_electrum: Uses the Wallet 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:

# zip 0.6.3 has MSRV 1.64.0
cargo update -p zip --precise "0.6.2"# time 0.3.21 has MSRV 1.65.0
cargo update -p time --precise "0.3.20"# jobserver 0.1.27 has MSRV 1.66.0
cargo update -p jobserver --precise "0.1.26"# home 0.5.9 has MSRV 1.70.0
cargo update -p home --precise "0.5.5"

The Bitcoin Dev Kit
BDK
A modern, lightweight, descriptor-based wallet library written in Rust!
Crate InfoMIT or Apache-2.0 LicensedCI StatusAPI DocsRustc Version 1.63.0+Chat on Discord
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 1.0 project page.
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:
  • example_cli: Library used by the example_* crates. Provides utilities for syncing, showing the balance, generating addresses and creating transactions without using the bdk Wallet.
  • example_electrum: A command line Bitcoin wallet application built on top of example_cli and the electrum crate. It shows the power of the bdk tools (chain + file_store + electrum), without depending on the main bdk library.
  • example_esplora: A command line Bitcoin wallet application built on top of example_cli and the esplora crate. It shows the power of the bdk tools (chain + file_store + esplora), without depending on the main bdk library.
  • example_bitcoind_rpc_polling: A command line Bitcoin wallet application built on top of example_cli and the bitcoind_rpc crate. It shows the power of the bdk tools (chain + file_store + bitcoind_rpc), without depending on the main bdk library.
  • wallet_esplora_blocking: Uses the Wallet to sync and spend using the Esplora blocking interface.
  • wallet_esplora_async: Uses the Wallet to sync and spend using the Esplora asynchronous interface.
  • wallet_electrum: Uses the Wallet 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:
# zip 0.6.3 has MSRV 1.64.0
cargo update -p zip --precise "0.6.2"# time 0.3.21 has MSRV 1.65.0
cargo update -p time --precise "0.3.20"# jobserver 0.1.27 has MSRV 1.66.0
cargo update -p jobserver --precise "0.1.26"# home 0.5.9 has MSRV 1.70.0
