Decoy Storages - Implements decoy storage architecture to hide real financial assets during forced disclosure.

Watch-Only Monitoring - Tracks balances and transactions for cold storage or paper wallets using public addresses and xpubs.

Partially Signed Bitcoin Transactions - Utilizes Partially Signed Bitcoin Transactions (PSBT) to coordinate signing between connected interfaces and air-gapped hardware.

UTXO Coin Control - Allows users to label, analyze, and freeze specific coins to control exactly which outputs are used.

BlueWallet is a Bitcoin wallet application that provides a mobile interface for managing Bitcoin assets, including standard wallets and specialized tools for Lightning Network payments. It serves as a coordinator for various wallet types, including multisig vaults and watch-only interfaces.

The project distinguishes itself through advanced security and privacy features, such as decoy storage architecture to hide assets during forced disclosure and custom entropy generation using physical dice or coins. It supports air-gapped transaction management via QR codes and PSBT integration for hardware wallet connectivity, ensuring private keys remain isolated from the internet.

The application covers a broad range of capabilities, including granular UTXO management for individual coin selection and the ability to connect to personal or remote Bitcoin and Lightning nodes for increased sovereignty. It also provides tools for multisig quorum coordination, transaction fee control, and balance monitoring for cold storage.
