OneKey review
Last reviewed 2026-08-25
Security warning
OneKey is a family rather than a single device, so the model you pick matters more than the brand you pick. Its own store runs from the Classic 1S Pure at $79, which is also sold in a bitcoin-only version at the same price, through the Classic 1S at $99, up to the OneKey Pro at $278. Two more products are backup rather than signing hardware: the OneKey Lite card at $25.90 and the metal KeyTag at $59.
The line's central claim is openness: OneKey develops its firmware and apps in public on GitHub, so what runs on the device can be read by anyone who cares to. The companion app is the other reason to look here, because it covers iOS, Android, Windows, macOS, Linux and a browser extension, which is wider than most hardware vendors manage. If you already use a browser wallet on a desktop and want hardware behind it, that breadth is the practical argument.
Specifications differ a lot across the range, screens, chips, Bluetooth and NFC included, so read the page for the exact device you are about to buy rather than the brand page. The store's own terms are worth knowing too: OneKey replaces a faulty device rather than repairing it, which means no repair technician ever handles hardware that held your keys, it sells through its own store and named resellers only, and it takes crypto at checkout.
On delivery, the store carries a bullet reading global shipping, free over $99. That is a shipping cost line, not a country policy. OneKey's help center shipping policy article no longer resolves, and neither the shop nor the product pages name a single country it will or will not serve, so this record lists none.

Pros and cons
What works
- Four signing models from $79 to $278, including a bitcoin-only Classic 1S Pure
- Companion app on iOS, Android, Windows, macOS, Linux and as a browser extension
- Firmware and apps are developed in public on GitHub
- Faulty devices are replaced rather than repaired, so no repair shop handles your hardware
What to watch
- Not bitcoin-only outside the Classic 1S Pure bitcoin edition
- Specifications vary widely across the range, so the brand name alone tells you little about the device you are buying
- No published shipping country policy: the help center article that should carry one returns a 404
- A shorter public track record than Ledger, Trezor or Coinkite
Worth comparing

- Keystone 3 ProAir-gapped signing on a 4 inch touchscreen, with three security chips and a fingerprint reader, at $149.
- BitBox02Swiss made, fully open source, sold in Multi and Bitcoin-only editions, with a Nova model that works from an iPhone.
Frequently asked questions
Is OneKey open source?
Yes. OneKey develops its firmware and apps in public on GitHub, which is the brand's main argument against closed firmware competitors. Check the repository for the exact model you are buying, since the line spans several generations.
Which OneKey should I buy?
The Classic 1S Pure at $79 is the entry point and comes in a bitcoin-only version at the same price. The Classic 1S is $99 and the OneKey Pro is $278. The Lite card and the KeyTag are seed backups rather than wallets, so neither replaces a signing device.
Does OneKey ship to my country?
OneKey publishes no country list. Its store advertises global shipping with free delivery over $99, its help center shipping article no longer exists, and the checkout is the only reliable test. It also sells through named resellers.
Is the OneKey Lite a hardware wallet?
No. It is a $25.90 card for backing up a recovery phrase, not a signing device. You still need a wallet such as a Classic 1S or a OneKey Pro to hold keys and approve transactions.
