Bitcoin Dev Kit

The Bitcoin Dev Kit (BDK) project (originally called Magical Bitcoin) aims to build a collection of tools and libraries that are designed to be a solid foundation for cross platform Bitcoin wallets, along with a fully working reference implementation wallet called Magical Bitcoin. All BDK components are designed to be lightweight and modular so that they can be adapted for virtually any use-case: from single-sig mobile wallets to multi-billion-dollar cold storage vaults. The main long-term goal is to concentrate the development efforts of multiple people and companies into one open source and very well reviewed project, instead of dispersing them over multiple closed/semi-closed or poorly designed projects.
