Introduction

Sparrow is a Bitcoin-onlydesktop wallet for macOS, Windows and Linux. Paired with a hardware wallet it never holds your private keys: it builds the transaction, the device checks and signs it, and Sparrow broadcasts the result. This guide covers the three ways to connect a device — USB, QR code and microSD card — with the steps from Sparrow's own documentation and the makers' guides.

TL;DR

Sparrow is Bitcoin-only and desktop-only (macOS, Windows, Linux); the keys stay on your hardware wallet.
Verify the download before installing: Sparrow 1.8.3+ does it under Tools > Verify Download.
USB: File > New Wallet > Connected Hardware Wallet > Scan. Close the maker's app first.
QR or microSD: File > New Wallet > Airgapped Hardware Wallet, then pass the transaction as an animated QR code or a PSBT file.
A public server sees your addresses; for larger amounts Sparrow recommends your own Bitcoin Core node.

Why pair Sparrow with a hardware wallet

Sparrow is a Bitcoin-only wallet with full PSBT support: it prepares a partially signed Bitcoin transaction, hands it to your hardware wallet to sign, and broadcasts the signed result. With a hardware wallet attached, Sparrow holds only the public keys, so it can show balances and build transactions but cannot spend on its own.

What it adds over most makers' own apps is control: coin control (choosing which coins to spend), labels on every address and transaction, a choice of server including your own node, and multisig. It is a desktop application; Sparrow's download page lists builds for macOS, Windows and Linux, plus a headless Sparrow Server build for Linux, and no phone app.

Step 1: Download and verify Sparrow

Download Sparrow only from sparrowwallet.com/download or the project's GitHub releases (2.5.6 was the current release on 31 October 2026). Then verify it, because a tampered wallet app is the one thing a hardware wallet cannot protect you from.

If you already run Sparrow 1.8.3 or newer: put the installer, the manifest (.txt) and its signature (.asc) in one folder and drag one of them onto Sparrow, or use Tools > Verify Download.
First install: import Craig Raw's PGP key from Keybase, run gpg --verify on the manifest signature, and expect a good signature from RSA key D4D0D3202FC06849A257B38DE94618334C674B40. Then check the installer's SHA-256 against the manifest (shasum --check on macOS, sha256sum --check on Linux, CertUtil -hashfile … SHA256 on Windows). The signature only proves the manifest is genuine; the hash check proves the installer matches it.

Step 2a: Connect by USB (Trezor, Ledger, BitBox02, Jade, Coldcard)

Set the device up first with its maker's software (firmware, recovery phrase, PIN). Then:

Close the maker's app — Trezor Suite, Ledger Wallet (formerly Ledger Live), BitBoxApp. Only one application can talk to the device at a time.
Connect and unlock the device.
In Sparrow: File > New Wallet, give it a name, choose Connected Hardware Wallet, click Scan…, then Import Keystore and Apply. Set a wallet password when asked.

Device-specific points from Sparrow and the makers:

Ledger: open the Bitcoin app on the device ("Bitcoin is ready") and keep Ledger Wallet closed.
BitBox02: close BitBoxApp completely and confirm the pairing code shown in Sparrow and on the device.
Coldcard: USB is off by default; turn it on under Settings > Hardware On/Off > USB Port. Coinkite itself recommends microSD or QR instead.
Linux: if nothing is detected, install the udev rules from Tools > Install Udev Rules.

Since version 2.1.0 Sparrow talks to USB devices through its own library, Lark; earlier versions bundled HWI.

Step 2b: Connect air-gapped by QR code (Keystone, Passport, Jade, Coldcard Q)

QR mode needs a webcam on the computer. Sparrow's QR guide names Coldcard Q (the only Coldcard with a camera), Keystone, Passport, Blockstream Jade, SeedSigner, Specter DIY, Krux, Keycard Shell and ERA Wallet.

On the device, open its export screen for Sparrow (on Keystone: Settings > Watch-Only Wallet > Sparrow Wallet; on Passport: Connect Wallet > Sparrow).
In Sparrow: File > New Wallet > Airgapped Hardware Wallet, find your device, click Scan… and hold the animated QR code to the webcam. Click Apply.
To send: create the transaction, click Finalize Transaction for Signing > Show QR, scan it with the device, check the amount and address on its screen, sign, then Scan QR the signed transaction back into Sparrow and click Broadcast Transaction.

Sparrow uses UR-standard animated QR codes, so even large transactions fit.

Step 2c: Connect air-gapped by microSD (Coldcard, Keystone, Passport)

The card should be FAT32 or FAT12 and at least 512 MB. On a Coldcard, check the firmware first (Advanced > Upgrade > Show Version): Sparrow requires at least 5.6.0 on Mk4 and Mk5, 1.5.0Q on Coldcard Q and 4.2.0 on Mk3, because older versions had a wallet-creation bug.

On the Coldcard, export the wallet for Sparrow (on recent firmware: Advanced/Tools > Export Wallet > Sparrow > MicroSD; older firmware writes a generic JSON file).
In Sparrow: File > New Wallet > Airgapped Hardware Wallet > Coldcard Import File…, choose the file, click Apply.
To send: Finalize Transaction for Signing > Save PSBT to the card. On the Coldcard choose Ready to Sign, check and sign. Back in Sparrow, Load PSBT the signed file and broadcast it.

Check every receiving address and every amount on the hardware wallet's own screen before you confirm. Sparrow cannot spend without the device — but a compromised computer can show you a wrong address.

Which hardware wallets work with Sparrow

Sparrow's own guides name Trezor, Ledger, Coldcard, BitBox02, Blockstream Jade, KeepKey and OneKey for USB; the QR and SD-card devices are listed above. Our software compatibility matrix, filtered to Sparrow, shows each device we review with how it connects and the source for every entry, next to Electrum, Nunchuk, Specter, BlueWallet, MetaMask and Rabby.

Step 3: Choose how Sparrow reaches the Bitcoin network

Sparrow needs a server to read the blockchain. It offers three:

Public Electrum server: quickest to start. Your funds are never at risk, but the server sees your public key information, so your privacy is shared. Sparrow's own best-practice guide places it at up to about US$10,000.
Your own Bitcoin Core node: set server=1 in bitcoin.conf. Pruned nodes work but cannot find transactions older than the blocks they keep. Sparrow's guide suggests this for up to about US$100,000 in a single-signature wallet.
Your own Electrum server (Fulcrum, ElectrumX, Electrs and others): the setup Sparrow names for expert use and multisig.

Tor is built in but optional: set a Tor proxy or a .onion server address and Sparrow routes its connections through it.

Coin control, labels and multisig

Coin control: on the UTXOs tab, select the coins you want (Ctrl/Cmd-click for several) and click Send Selected. Without a selection Sparrow picks coins automatically, using the same selection methods as Bitcoin Core.
Labels: every address, transaction, input and output can carry a label, and Sparrow labels outgoing payments for you.
Multisig: Sparrow builds multisig wallets from several hardware wallets, recommends mixing makers, and caps a wallet at 16 cosigners (15 for legacy P2SH) in its current code.
Taproot: supported for single-signature wallets.

Common problems and fixes

Device not found: unlock it, close the maker's app, try another USB cable or port; on Linux install the udev rules.
Ledger will not connect: close Ledger Wallet, open the Bitcoin app, and on Windows check that antivirus is not blocking Sparrow and that nothing else uses ports 2222, 21324, 11044 or 9999.
Trezor on Windows: a missing driver may need installing with Zadig (WinUSB), then a reboot.
BitBox02 on Linux: older BitBoxApp versions keep the device to themselves — quit the app, unplug and reconnect.
Addresses look different from before: almost always a different passphrase.
Funds missing after a restore: raise the gap limit (default 20).

Alternative: Electrum

Electrum is the older Bitcoin-only wallet with hardware support for Trezor, Ledger, KeepKey, BitBox02, Coldcard and Jade, among others. Unlike Sparrow it also has an Android build. Sparrow can import and export Electrum wallet files, so moving between the two is straightforward. Neither project publishes a comparison of the two; check the device you own in the matrix linked above.

Frequently Asked Questions

Common questions about hardware wallets and crypto security

Does Sparrow store my private keys?

Not when you use it with a hardware wallet. Sparrow keeps only the public keys, so it can show your balance and prepare transactions, while the device holds the private keys and signs.

Can I use Sparrow on my phone?

No. Sparrow's download page lists only desktop builds for macOS, Windows and Linux, plus a headless server build for Linux. For a phone, Nunchuk and BlueWallet are the Bitcoin apps in our matrix with mobile versions.

Does Sparrow support Ethereum or other coins?

No. Sparrow is Bitcoin-only. For Ethereum and EVM networks, look at MetaMask or Rabby with a hardware wallet.

Is a public server safe to use?

Your funds are not at risk, because the server never sees your private keys. It does see your addresses and balances, which is why Sparrow advises your own Bitcoin Core node or Electrum server for significant amounts.

Which is better for a first setup: USB or QR?

USB is the quickest if your device supports it (Trezor, Ledger, BitBox02). QR and microSD keep the device off the computer entirely, at the cost of a few extra steps per transaction. Both use the same Sparrow wallet features.
