Overview
bdk_flutter is a Flutter library that integrates the Bitcoin Development Kit (bdk) into Flutter applications, enabling developers to build secure, native Bitcoin wallets with full control over key management, transaction creation, and blockchain interaction. It provides a bridge to bdk's robust Rust-based backend, offering features like HD wallet support, PSBT handling, and blockchain synchronization. Designed for Web3, crypto, and blockchain apps, it empowers developers to create lightweight, privacy-focused Bitcoin solutions across Android, iOS, and macOS platforms.
