Best hardware wallets for Sparrow Wallet

Every device here is Bitcoin-only, sold today, and named in the source code of Sparrow 2.5.6, the current release from October 29, 2026. Sparrow keeps its list of supported devices in one file, talks to USB devices through its own library, Lark, and lists its QR and file importers in its airgapped import screen. Every cell in the table below comes from those three files.

The ranking order comes from my rating methodology. If you have not set up Sparrow yet, start with my guide to set up and verify Sparrow, then come back for the device.

SeedSigner is a signing device you build from a Raspberry Pi Zero, a camera, and a small screen, usually for under $50. It is stateless: the seed leaves memory when you unplug it, so you load it from a SeedQR or your words each time. The project lists Sparrow among the coordinators it was built for.

In Sparrow, choose Airgapped Hardware Wallet and pick SeedSigner. Sparrow's importer says to "Import QR created on your SeedSigner by selecting Export Xpub in the Seeds menu", and it has no file option, so everything moves by QR. Sparrow keeps the wallet file, which suits a device that remembers nothing.

The con: in September, SeedSigner merged a fix that makes it verify that change outputs actually pay this seed, and the latest release, 0.8.7 from July, predates it. Until the next release ships, check the change address in Sparrow against the one on the SeedSigner screen. More in my SeedSigner review.

Jade Plus is the one pick here that gives you both paths. Over USB, Sparrow talks to it through Lark, which lists Jade. Air-gapped, it has a built-in camera for QR signing, and Sparrow's importer reads the QR from **Options > Wallet > Export Xpub** on the device. Blockstream's store lists Sparrow as compatible, at $149 in plastic or $169 in metal.

I'd use QR mode with Sparrow. In 2025 DARKNAVY found a buffer overflow in Jade's descriptor registration command, fixed in 1.0.37, and Blockstream wrote that "QR mode is not vulnerable as it does not expose an RPC interface at all." Read the full Jade Plus review or BitBox02 vs Jade Plus.

Krux is open-source firmware for off-the-shelf Kendryte K210 devices such as the Maix Amigo and M5StickV, and it talks to coordinators through QR codes, SD cards, and thermal printers. Sparrow's importer accepts a file or QR from the Extended Public Key menu, and Krux is one of the few models for which Sparrow shows BBQr codes, a denser QR format.

Cost depends on the board, and some need assembly. The project calls itself a research and development project, so expect less polish than a commercial wallet. The latest release is v26.09.0 from October 3. See my Krux review or Krux vs SeedSigner.

The original Jade connects to Sparrow the same two ways as the Jade Plus: USB through Lark, or QR with its camera. It was $67 on Blockstream's store, down from $79, when I checked on November 5, 2026, and the same QR-mode advice applies. You trade screen size and battery for the lower price. Compare them in Jade vs Jade Plus, or read my Jade review.

Specter DIY uses an STM Discovery board and a Waveshare QR scanner, so you buy the parts from ordinary electronics shops. QR codes are its default way to talk to a computer, and Sparrow's importer takes a file or QR from its Master Public Keys screen. It is not in Sparrow's USB list, so treat it as an air-gapped device in Sparrow.

The latest firmware, v1.10.5 from September 6, hardened its random number handling and its change detection. See my Specter DIY review or SeedSigner vs Specter DIY.

Jade Core's store page lists USB-C and Bluetooth as its connections, with Sparrow among the compatible apps, for $99. It has no camera (see my Jade Core review), so there is no QR path. Sparrow's Jade driver opens a USB serial port, so in Sparrow this is a USB device. The original Jade costs less and has a camera.

On Passport Prime, open the Bitcoin app, tap the account, and choose Connect Wallet; Sparrow is on Foundation's list of companion wallets. You scan the QR into Sparrow or save a file, then move transactions by QR or by a USB drive or microSD card on USB-C. Sparrow's importer names the same Connect Wallet > Sparrow path. It costs $349.

Two cons. Foundation says "QuantumLink is required for initial setup and for syncing with Envoy", its Bluetooth link, so it is air-gapped only after setup. And my incident tracker logs five major Foundation entries in 2026, the latest phishing emails sent from Foundation's own domains in October. Read my Passport Prime review or Passport Prime vs Jade Plus.

Lark lists BitBox02 for all models, so the original and the Nova both connect to Sparrow over USB. BitBox lists Sparrow with single-sig and multisig support. There is no QR or SD path. BitBox's shop blocked my price check on November 5, 2026, so check the current price on its Bitcoin-only edition page.

The con: my incident tracker logs three major BitBox02 firmware fixes in 2026: a bootloader flaw, a USB out-of-bounds write, and a silent payments bug, all shipped in the July and August updates. Update the firmware before you pair it. Read my BitBox02 review.

Trezor sells Bitcoin-only editions of all three: the Safe 3 at $59, the Safe 5 at $129, and the Safe 7 at $249, all listed in stock when I checked on November 5, 2026. Trezor says "the Switch to Universal button is not shown on Bitcoin-only Trezor hardware wallets", so the edition you buy stays Bitcoin-only. Sparrow talks to all three over USB through Lark, which maps the Safe 3, Safe 5, and Safe 7 to Sparrow's device list. Sparrow's model file does not ask for their PIN or passphrase on the computer, as it does for the OneKey, so you enter both on the device. There is no QR or SD path.

The con is Trezor's year. My incident tracker logs major Bitcoin-relevant entries in 2026: RBF replacements that could add a recipient without confirmation, CoinJoin signing that accepted some unverifiable inputs, a multisig fee-bump display bug, a shipping-partner breach that exposed 80,689 customers, a phishing email from Trezor's newsletter account, and in October an implant reported in a Safe 5 sold by a reseller. The Safe 7's TROPIC01 secure element was also broken by laser fault injection. Buy from trezor.io, never a reseller, and update the firmware before you pair it. Read my Trezor Safe 3, Safe 5, and Safe 7 reviews.

Sparrow supports it over USB through Lark, which lists the OneKey Classic 1S. But Sparrow's model file marks the Classic 1S as needing a PIN prompt and passphrase entry on the computer, the same flow as the old Trezor One. Typing your PIN and passphrase on the machine you are trying not to trust is the weakest setup on this list.

OneKey sells it at $79 and says it "Ships with BTC-only system. Switch to Multi-coin system anytime." Keep it on the Bitcoin-only system. My incident tracker also logs a 2026 major entry for OneKey, a researcher talk on fault injection against its chips. More in my OneKey Classic 1S Bitcoin Edition review.

USB is the fastest: plug in, and Sparrow finds the device under Connected Hardware Wallet. The device also opens a data channel the computer can talk into. Jade's 2025 bug was reachable over USB and Bluetooth, and Blockstream wrote that QR mode does not expose an RPC interface at all.

QR and file keep the device off the computer. Sparrow shows the unsigned transaction as an animated QR (it supports the UR standard for any PSBT length), the device scans it, you check the address and amount on its screen, and Sparrow scans the signed QR back. A file on an SD card does the same job without a camera.

I pick QR when the device offers it. My air-gapped hardware wallets page covers that side in more depth.

Sparrow 2.5.6's device list has no entry for Bitkey or Portal, and neither appears in Lark's USB list or the airgapped importers. You cannot add either one to a Sparrow wallet. Bitkey works with its own app; read my Bitkey review. Portal is off my "Best" lists anyway: TwentyTwo's store returned a server error when I checked on November 5, 2026.

Sparrow's device list includes Coldcard and Coinkite's TAPSIGNER, SATSCARD, and SATSCHIP cards (source), and plenty of guides pair Sparrow with a Coldcard. I don't recommend any Coinkite product. Here is why I delisted Coldcard.

Sparrow also supports Trezor, Ledger, and Keystone models. I don't rank the multi-coin versions. More coins means more code, and more code means more bugs near your keys.
