Bitcoin Development Kit (BDK) is a suite of software libraries that allows you to build secure, feature-rich, and cross-platform Bitcoin wallets.
Most of the BDK projects are based on the powerful rust-bitcoin and rust-miniscript libraries.
The home page for the overarching BDK project and the BDK Foundation that supports it is bitcoindevkit.org.
We provide the technical infrastructure to maintain a number of software and documentation projects across different maturity levels and support models. To help you navigate these projects, we've categorized them along two dimensions: Maturity Level (Stable or Experimental) and Support Model (Foundation or Community). See "The Book of BDK" chapter on library tiers for more details.
- bdk_wallet - A modern, lightweight, descriptor-based wallet rust crate.

- bdk_core - A collection of core structures used by the bdk_chain, bdk_wallet, and BDK's chain data source crates.
- bdk_esplora - Extends the esplora-client crate with methods to fetch blockchain data for bdk_chain and bdk_wallet to consume.
- bdk_electrum - Extends the electrum-client crate with methods to fetch blockchain data for bdk_chain and bdk_wallet to consume.
- bdk_bitcoind_rpc - Emits blockchain data from the bitcoind RPC interface for bdk_chain and bdk_wallet to consume.
