Connecting your hardware wallet to a trusted digital asset management platform is a crucial step in securing and managing your cryptocurrency holdings. The Keystone hardware wallet, known for its air-gapped security, can now be seamlessly integrated with the OKX Wallet extension—a powerful, user-friendly browser-based crypto wallet that supports multiple blockchains and decentralized finance (DeFi) features.
This guide walks you through the complete process of connecting your Keystone 3 Pro to the OKX Wallet extension, enabling secure access to essential functions like sending, receiving, and swapping tokens across EVM-compatible chains and Bitcoin.
Whether you're new to self-custody wallets or expanding your DeFi toolkit, this step-by-step tutorial ensures a smooth and secure setup.
Supported Chains and Key Features
Before diving into the setup, it’s important to understand what’s supported:
- Supported Chains: Bitcoin (BTC) and all EVM-compatible blockchains (e.g., Ethereum, BSC, Polygon, Arbitrum, Optimism)
- Available Features: Send and receive crypto, swap tokens via decentralized exchanges (DEXs), interact with dApps, and view portfolio analytics
By combining Keystone’s offline signing capability with OKX Wallet’s intuitive interface, you gain both maximum security and convenient access to the broader Web3 ecosystem.

Step 1: Prepare Your Devices and Software
To ensure a successful connection between your Keystone hardware wallet and the OKX Wallet extension, follow these prerequisites carefully.
✅ Firmware Requirements
Make sure your Keystone 3 Pro is running firmware version 1.2.6 or higher. You can update your device using the official Keystone firmware updater:
- Visit the Keystone firmware download page to check for updates.
- Follow the on-screen instructions to install the latest firmware via microSD card.
🔐 Why this matters: Newer firmware versions include critical security patches and improved compatibility with third-party wallets like OKX.
✅ Install the OKX Wallet Browser Extension
The OKX Wallet is available as a browser extension for Chrome and other Chromium-based browsers (e.g., Brave, Edge).
- Open your browser and navigate to the Chrome Web Store.
- Search for “OKX Wallet” or directly install from the official source.
- Click “Add to Chrome” and confirm the installation.
- Once installed, pin the extension for easy access.
⚠️ Always verify the publisher is “OKX” and check user reviews before installing any crypto extension.
After installation, you’ll see the OKX icon appear in your browser toolbar—this is your gateway to managing digital assets with confidence.
Step 2: Connect Keystone to OKX Wallet
Now that both devices are ready, it’s time to establish a secure connection using QR code pairing—a method that preserves Keystone’s air-gapped security model while allowing seamless interaction with online services.
On Your Keystone Hardware Wallet
- Power on your Keystone 3 Pro.
- Tap the “…” (More Options) icon on the home screen.
- From the menu, select [OKX Wallet].
- A static QR code will appear on the screen. This code contains your public key information but does not expose private keys.
🛡️ Security Note: Since no private data leaves the device, this process remains fully offline and immune to remote attacks.
In the OKX Wallet Extension
- Click the OKX Wallet icon in your browser.
- Choose “Import wallet” (not “Create wallet”).
- Select “Hardware Wallet”, then tap “Keystone” from the list of supported devices.
- When prompted, allow OKX Wallet to access your camera.
- Position your Keystone device so the camera can clearly scan the QR code.
- Once scanned successfully, OKX will display available accounts derived from your seed phrase.
Finalize Setup
- Select the account you’d like to use as your primary wallet.
- Set a strong password to encrypt local data in the extension.
- Optionally, skip password creation by selecting “Maybe later,” though this is not recommended for long-term use.
🎉 Success! You’re now logged into OKX Wallet with your Keystone-connected account.
You can begin exploring supported features immediately—send crypto, track balances, or dive into DeFi with peace of mind knowing your private keys never leave your hardware device.

Frequently Asked Questions (FAQ)
Q1: Is my private key ever exposed during this process?
No. The connection uses QR code-based public key exchange. Your private keys remain securely stored within the Keystone device at all times, preserving its air-gapped nature.
Q2: Can I connect multiple accounts from the same Keystone?
Yes. OKX Wallet allows you to import multiple accounts derived from the same seed phrase. Simply repeat the scanning process and choose a different account index if needed.
Q3: Does this work with non-EVM chains like Bitcoin?
Yes! While transaction signing for BTC occurs directly on Keystone, OKX Wallet can display your Bitcoin balance and allow you to initiate sends—always confirmed offline on the hardware device.
Q4: What should I do if the QR code fails to scan?
Ensure good lighting and clean camera lens. If issues persist:
- Restart both devices
- Reopen the OKX Wallet extension
- Regenerate the QR code by exiting and reselecting [OKX Wallet] on Keystone
Q5: Can I use this setup on mobile?
Currently, this integration is optimized for desktop browsers. Mobile support may become available in future updates.
Q6: Do I need internet access on my Keystone?
No. The Keystone remains completely offline. Only your computer/browser needs internet access to broadcast transactions signed offline by the device.
Maximizing Security and Usability
With your Keystone + OKX Wallet setup complete, consider these best practices:
- Regularly back up your 24-word recovery phrase in a fireproof, waterproof location.
- Keep firmware and software updated to benefit from new features and protections.
- Use the password protection feature in OKX Wallet to prevent unauthorized access if your computer is compromised.
- Monitor transaction details carefully on both the OKX interface and your Keystone screen before approving.
This combination delivers an ideal balance: the ironclad security of cold storage with the convenience of a hot wallet interface.
Why This Integration Matters for Crypto Users
As decentralized applications grow more complex, users need tools that don’t force trade-offs between security and functionality. The Keystone-OKX Wallet integration eliminates that compromise.
Whether you’re trading on DEXs, participating in token launches, or simply storing value across chains, this setup empowers you with full control—without sacrificing ease of use.
