Sparrow Wallet Review

Sparrow Wallet scores 8.8 out of 10, second of the six wallets in our wallet ratings. It has the strongest marks in the category for custody, open source and hardware support, and nothing to hide on fees. It is held back by a single deliberate choice: it handles Bitcoin and nothing else.

How Sparrow Wallet scores in wallets

Every wallet in this category is marked on five criteria, each from 0 to 10 and each carrying equal weight. This entry is based on desk research of Sparrow's website and documentation and its GitHub repository. We did not test the wallet hands-on.

The overall score is the plain average: (10 + 10 + 4 + 10 + 10) / 5 = 44 / 5 = 8.8.

One mark changed. We re-opened the homepage and the repository on 1 November 2026, and both still state the Apache 2 licence, the hardware wallet support and the server options the July 2026 marks relied on. Fee transparency then rose from 9 to 10 under the category's scale rule of 2 November 2026, which counts a wallet that states it charges no fee of its own as fully transparent. The score moves from 8.6 to 8.8.

Strongest criteria

Custody & key control: 10

Sparrow is self-custodial in the fullest sense the rubric measures. There is no company account. Wallet files live in a local folder, and in the usual setup Sparrow keeps only public keys while a hardware device signs. Sparrow can also connect to your own Bitcoin Core node or a private Electrum server, so balances do not have to be looked up through someone else's server. Its best-practices guide warns that a public server can see your balance and IP address, which is why it describes a path from public servers to your own.

Open source: 10

The homepage and the repository both state that Sparrow is licensed under the Apache 2 software licence, a recognized open-source licence that allows anyone to read, modify and redistribute the code. Releases are signed, and the download page explains how to verify an installer against its signed hash manifest. This is the only plain open-source licence in the category. Rabby's MIT licence reserves its brand, and MetaMask's is limited to non-commercial use.

Hardware wallet support: 10

The homepage claims support for all common hardware wallets in USB and air-gapped modes, and the documentation lists the devices: Trezor, Ledger, BitBox02 and Jade over USB; Passport, Jade, SeedSigner, Keystone and Krux by QR code; Coldcard, Keystone and Passport by SD card; and several smartcards. Signing uses Partially Signed Bitcoin Transactions (PSBT), the standard format hardware wallets use. Our hardware wallet security guide explains what an air-gapped signer protects.

Fee transparency: 10

Sparrow sells nothing inside the app: there is no buy, sell or swap service, so there is no markup to disclose, and the software itself is free, funded by donations. Under the category's scale, a wallet that charges no fee of its own is as transparent as one that publishes a fixed fee, so the mark is 10. The only cost of a transaction is the Bitcoin network fee, which Sparrow lets you set and edit directly through coin and fee control.

Weakest criterion

Chain & asset coverage: 4, a measured limit

Sparrow supports Bitcoin, plus test networks for developers. It does not hold Ethereum, Solana, stablecoins or any other asset, and there is no mobile app. This is a design choice, not missing evidence, and the rubric scores it as a real limitation for anyone who holds more than bitcoin. It is the lowest coverage mark in the category.

What the score does not cover

• Ease of use. Sparrow is built around coin control, PSBT and server choice. The rubric does not score how hard that is for a newcomer.
• Privacy tools. PayNym codes, built-in Tor and "fake coinjoin" spending are not scored. Sparrow's Whirlpool coinjoin client was removed in version 1.9.0, so older guides describing it are out of date.
• Support. There is no company and no phone line. Issues go through GitHub, and anyone offering "Sparrow support" by phone is not part of the project.

Sparrow Wallet vs Rabby and MetaMask

The six rated wallets stand at Rabby Wallet 9.0, Sparrow Wallet 8.8, MetaMask 7.8, Phantom 7.4, Exodus 7.0 and Trust Wallet 6.4. Rabby, 0.2 ahead, scores lower than Sparrow on custody and open source (9 each against 10). It moves ahead on coverage (7 against 4). Both score 10 on fees and hardware support: Rabby publishes a fixed 0.25% fee, and Sparrow charges none of its own. MetaMask, 1.0 behind, is stronger only on coverage (8 against 4). Sparrow leads it on open source by seven points (10 against 3). MetaMask now holds Bitcoin addresses too, but its hardware accounts are EVM-only, so it cannot sign bitcoin transactions on a hardware device the way Sparrow does.

Who it suits

The score suits Bitcoin holders who use a hardware wallet, want to run or connect to their own node, and value an open-source licence. It does not suit anyone who needs other assets, a phone app or a built-in exchange. Before using any desktop wallet, back up your recovery phrase offline; our seed phrase guide covers the options.
