Connecting your Keystone hardware wallet to OKX Wallet is a secure and straightforward process that empowers you to manage your digital assets with confidence. Whether you're using the OKX mobile app or the OKX Wallet browser extension, this guide walks you through each step to ensure a seamless integration between your cold storage device and one of the most versatile self-custody wallets in the crypto ecosystem.
With support for BTC and multiple EVM-compatible chains, OKX Wallet enables users to send, receive, swap tokens, interact with decentralized applications (dApps), and access decentralized exchanges (DEXs) — all while keeping private keys securely stored on your Keystone device.
Why Connect Keystone to OKX Wallet?
Keystone hardware wallets, including the Keystone 3 and Keystone 3 Pro, offer military-grade security by storing private keys offline. When paired with OKX Wallet, you gain the best of both worlds: top-tier security and user-friendly access to Web3 features.
This combination allows you to:
- Approve transactions securely via air-gapped QR code scanning
- Interact with DeFi protocols without exposing your keys
- Manage multiple blockchain assets from a single interface
👉 Discover how easy it is to secure your crypto while accessing DeFi.
Prerequisites: What You’ll Need
Before starting the connection process, ensure you have the following:
- A Keystone 3 or Keystone 3 Pro hardware wallet
- The OKX mobile app installed on your smartphone (available on the App Store or Google Play)
- Or the OKX Wallet browser extension added to your desktop browser
- A stable internet connection
- Your Keystone wallet charged and ready
Make sure your devices are free from malware and only download software from official sources to maintain maximum security.
Step-by-Step: Connecting via OKX Mobile App
Follow these steps to securely link your Keystone hardware wallet with the OKX mobile application.
1. Open OKX App and Navigate to Wallet
Launch the OKX app and tap on the Wallet tab at the bottom of the screen. Then select "I already have one" to proceed with an existing wallet setup.
2. Choose Hardware Wallet Option
From the list of wallet types, choose Hardware Wallet, then select Keystone as your device type.
3. Scan the QR Code from Your Keystone
On your Keystone device:
- Navigate to the OKX Wallet app
- A dynamic QR code will appear on the screen
Back in the OKX app, tap Scan to connect and use your phone’s camera to scan the QR code displayed on your Keystone. Follow any on-screen prompts carefully.
🔐 This QR code contains no sensitive data — it's part of an air-gapped authentication protocol that keeps your private keys safe.
4. Select Account to Connect
Once the scan is successful, you'll be prompted to choose which account (e.g., Bitcoin, Ethereum, etc.) you'd like to link. You can connect multiple accounts across different blockchains.
After confirmation, your Keystone is now fully integrated with OKX Wallet through the mobile app.

Step-by-Step: Connecting via OKX Wallet Browser Extension
If you prefer using desktop browsers for dApp interactions or trading on DEXs, follow this method to connect via the browser extension.
1. Install and Open OKX Wallet Extension
Download the OKX Wallet browser extension from the official website and install it on Chrome, Edge, or other compatible browsers.
Click on the extension icon and select Import wallet.
2. Select Hardware Wallet > Keystone
In the import options, choose Hardware Wallet, then pick Keystone from the list of supported devices.
3. Grant Camera Access and Scan QR Code
The extension will request permission to access your device’s camera. Allow this so it can scan the QR code generated by your Keystone.
Go back to your Keystone device:
- Open the OKX Wallet app
- Wait for the QR code to appear
- Use your computer’s webcam (via the browser) to scan it
4. Choose Accounts and Set Password
After scanning, select the blockchain accounts you want to import into the extension interface.
You’ll then be asked to create a strong password — this protects local data within the extension but does not store your private keys.
Your connection is now complete. You can begin interacting with Ethereum-based dApps, swapping tokens, or exploring NFT marketplaces — all with transaction signing handled securely by your Keystone.
