The Bitcoin Dev Kit

A suite of libraries for building modern, lightweight, descriptor-based wallets written in Rust!

MIT or Apache-2.0 LicensedCI StatusRustc Version 1.63.0+Chat on Discord

Project Homepage

About

The bdk libraries aim to provide well engineered and reviewed components for Bitcoin wallets and other applications. They are built upon the excellent rust-bitcoin and rust-miniscript crates.

Architecture

The workspace in this repository contains several crates in the /crates directory:

Sub-DirectoryDescriptionBadges
chainTools for storing and indexing chain data.Chain Crate InfoChain API Docs
coreA collection of core structures used by the bdk_chain, bdk_wallet, and BDK's chain data source crates.Core Crate InfoCore API Docs
esploraExtends 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.Esplora Crate InfoEsplora API Docs
electrumExtends the electrum-client crate with methods to fetch chain data from an electrum server in the form that bdk_chain and Wallet can consume.Electrum Crate InfoElectrum API Docs
bitcoind_rpcExtends bitcoincore-rpc for emitting blockchain data from the bitcoind RPC interface in the form that bdk_chain and Wallet can consume.BitcoinD RPC Crate InfoBitcoinD RPC API Docs
file_storePersistence backend for storing chain data in a single file. Intended for testing and development purposes, not for production.File Store Crate InfoFile Store API Docs

The bdk_wallet repository and crate contains a higher level Wallet type that depends on the above lower-level mechanism crates.

Fully working examples of how to use these components are in /examples:

  • 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 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_wallet 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_wallet 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_wallet library.

Minimum Supported Rust Version (MSRV)

The following BDK crates maintains a MSRV of 1.63.0. To build these crates with the MSRV of 1.63.0 you will need to pin dependencies by running the pin-msrv.sh script.

  • bdk_core
  • bdk_chain
  • bdk_bitcoind_rpc
  • bdk_esplora
  • bdk_file_store

The MSRV of the bdk_electrum crate is 1.75.0.

About
The bdk libraries aim to provide well engineered and reviewed components for Bitcoin wallets and other applications.
They are built upon the excellent rust-bitcoin and rust-miniscript crates.
Architecture
The workspace in this repository contains several crates in the /crates directory:
Sub-DirectoryDescriptionBadges
chainTools for storing and indexing chain data.Chain Crate InfoChain API Docs
coreA collection of core structures used by the bdk_chain, bdk_wallet, and BDK's chain data source crates.Core Crate InfoCore API Docs
esploraExtends 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.Esplora Crate InfoEsplora API Docs
electrumExtends the electrum-client crate with methods to fetch chain data from an electrum server in the form that bdk_chain and Wallet can consume.Electrum Crate InfoElectrum API Docs
bitcoind_rpcExtends bitcoincore-rpc for emitting blockchain data from the bitcoind RPC interface in the form that bdk_chain and Wallet can consume.BitcoinD RPC Crate InfoBitcoinD RPC API Docs
file_storePersistence backend for storing chain data in a single file. Intended for testing and development purposes, not for production.File Store Crate InfoFile Store API Docs
The bdk_wallet repository and crate contains a higher level Wallet type that depends on the above lower-level mechanism crates.
Fully working examples of how to use these components are in /examples:
  • 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 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_wallet 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_wallet 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_wallet library.
Minimum Supported Rust Version (MSRV)
The following BDK crates maintains a MSRV of 1.63.0. To build these crates with the MSRV of 1.63.0 you will need to pin dependencies by running the pin-msrv.sh script.
  • bdk_core
  • bdk_chain
  • bdk_bitcoind_rpc
  • bdk_esplora
  • bdk_file_store
The MSRV of the bdk_electrum crate is 1.75.0.
