Sparrow Wallet

Sparrow is a modern desktop Bitcoin wallet built for power users who want fine-grained control over privacy, fees, and transaction construction. It emphasizes transparency by providing a detailed byte-level transaction viewer and editable diagrams showing inputs and outputs with current fee estimates. Sparrow supports software keys (BIP39/SLIP-132 descriptors) or external hardware wallets including Coldcard, Ledger, Trezor, BitBox02, and Keystone. Connectivity options include Bitcoin Core full node, Electrum server (self-hosted or public), and Tor integration. Air-gapped flows via PSBT signing keep private keys off networked machines. Password security uses Argon2 configured for strong key derivation.
