Cove is a Bitcoin-only mobile wallet built on Bitcoin Dev Kit (BDK), designed to be simple to use and feature-rich for both new users and experienced Bitcoiners. It supports hot wallet functionality with encrypted local key storage, and deep hardware wallet integration with ColdCard, Krux, and Tapsigner via PSBT over QR codes and NFC. UTXO management comes with BIP329-compatible label synchronization. Decoy and wipe PIN protection guards against physical coercion. Built entirely on open-source foundations (BDK), with source code on GitHub (bitcoinppl/cove). Available on iOS and Android.
