## What it is
Sparrow is a free, open-source desktop Bitcoin wallet application built in Java with a focus on security, privacy, and transparency. It supports singlesig and multisig wallets, most hardware wallets (USB and airgapped), PSBT standards, and connects via public servers, Bitcoin Core, or private Electrum servers.

## Use cases
- manage a bitcoin wallet with full coin and fee control
- set up a multisig bitcoin wallet with hardware wallets
- sign bitcoin transactions offline with an airgapped device
- connect my wallet to my own Bitcoin Core or Electrum server for privacy
- inspect and edit raw bitcoin transactions before broadcasting
- store bitcoin securely with Argon2 encryption and reproducible builds

## When to choose
- you want a transparent, standards-based desktop wallet with detailed transaction and UTXO visibility
- you need broad hardware wallet support including airgapped QR/SD-card signing
- privacy matters and you want to progress from public servers to your own node
- you need multisig, output descriptors, testnet/signet/regtest support

## When to avoid
- you want a mobile or browser-based wallet
- you need support for cryptocurrencies other than Bitcoin
- you are a complete beginner who wants a minimal one-click wallet without configuration choices
