OneKey
OneKey is a hardware wallet brand whose multi-chain devices range from compact USB models to touchscreen wallets with Bluetooth, NFC and QR-code signing, all managed in the OneKey App.
What Is OneKey?
OneKey is a hardware wallet brand of ONEKEY LIMITED, whose GitHub organisation lists Hong Kong as its location. It makes multi-chain devices and the OneKey App that manages them; the company says the app supports more than 100 blockchains.
The range has two lines. The OneKey Classic 1S and the battery-free OneKey Classic 1S Pure are compact models with a small OLED screen. The OneKey Pro and OneKey Pro 2 add a colour touchscreen, Bluetooth, NFC and a camera for QR-code signing. The OneKey Neo has a touchscreen and a battery but no camera, so it signs over USB-C or Bluetooth.
Keys are held in secure elements, and the backup is a standard BIP39 recovery phrase of 12 or 24 words, so it is not tied to OneKey hardware. The Pro, Pro 2 and Neo also support SLIP-39, which splits the backup into several shares, and a passphrase can create .
The app and the microcontroller firmware for the Pro and Classic 1S are public on GitHub. The firmware that runs on the secure elements is closed on every model, and no public firmware repository for the Pro 2 and Neo had appeared as of November 2026. The app sends usage analytics and has no setting to turn them off.
A hardware wallet is a dedicated device that keeps private keys offline and signs transactions internally, so the keys never reach an internet-connected computer or phone.
A blockchain is a shared, append-only record of transactions kept by many independent computers, so no single party can rewrite it.

Example 1: To keep a OneKey Pro off any cable or radio link, a user signs by QR code: the app shows the unsigned transaction as a QR code, the device's camera scans it, and the signed result goes back the same way.
Example 2: A OneKey Classic 1S stops working. Its owner enters the 24-word BIP39 phrase on a compatible wallet from another manufacturer and reaches the same accounts.
Example 3: On a OneKey Pro 2, a user creates a SLIP-39 backup and stores the shares in separate places, so that a single share found by someone else does not reveal the wallet.
QR Code Signing is a method used in cryptocurrency transactions where a QR code is generated to confirm and sign a transaction, enhancing security and user convenience.

Frequently Asked Questions
Can I restore a OneKey wallet without OneKey hardware?
Yes. The backup is a standard BIP39 recovery phrase of 12 or 24 words, so it is not tied to OneKey hardware. If a device stops working, its owner can enter the phrase on a compatible wallet from another manufacturer and reach the same accounts. A SLIP-39 backup, available on the Pro, Pro 2 and Neo, splits the backup into several shares instead.
Which parts of OneKey are open source?
The OneKey App and the microcontroller firmware for the Pro and Classic 1S are public on GitHub. The firmware that runs on the secure elements is closed on every model, and no public firmware repository for the Pro 2 and Neo had appeared as of November 2026. The app also sends usage analytics and has no setting to turn them off.
How do the OneKey Pro and Neo differ in how they sign?
The OneKey Pro and Pro 2 have a camera, so they can sign by QR code without any cable or radio link: the app shows the unsigned transaction as a QR code, the device scans it and the signed result goes back the same way. The Neo has a touchscreen and a battery but no camera, so it signs over USB-C or Bluetooth.
