How to link a hardware wallet to OKX? (Web3 settings)

Accessing Web3 Wallet Settings on OKX

1. Log in to your OKX account via the official website or desktop application.

2. Navigate to the top-right corner and click on your profile icon.
3. Select Web3 Wallet from the dropdown menu.
4. If you haven’t activated Web3 features yet, confirm your identity using KYC verification steps.
5. Once verified, the Web3 Wallet dashboard opens, displaying supported networks and connection options.

Preparing Your Hardware Wallet

1. Ensure your hardware wallet firmware is updated to the latest version using its official software.

2. Install and open the compatible wallet app—such as Ledger Live for Ledger devices or Trezor Suite for Trezor models.
3. Enable blockchain app support for Ethereum, BSC, Arbitrum, and other EVM-compatible chains directly on the device.
4. Connect the hardware wallet to your computer using a certified USB cable.
5. Unlock the device and approve any prompts requesting access to blockchain applications.

Connecting via WalletConnect Protocol

1. In the OKX Web3 Wallet interface, click the Connect Wallet button.

2. Choose WalletConnect from the list of available options.
3. Scan the QR code displayed on screen using your hardware wallet’s companion mobile app—Ledger Live or Trezor Suite must have WalletConnect enabled.
4. Confirm the connection request on your hardware device’s physical screen.
5. After approval, OKX displays your wallet address and network status, indicating successful linkage.

Verifying Connection Integrity

1. Check that the displayed public address matches the one shown on your hardware wallet’s screen.

2. Initiate a small test transaction on a testnet like Sepolia or BSC Testnet to confirm signing capability.
3. Observe whether transaction requests appear on the hardware wallet’s display before confirmation.
4. Review the connected networks section to ensure only intended chains are enabled.
5. Disconnect and reconnect once to validate session persistence across browser refreshes.

Frequently Asked Questions

Q: Can I link multiple hardware wallets to one OKX account?A: Yes. OKX allows binding of several hardware wallets under a single Web3 Wallet profile. Each connection operates independently and supports different addresses per chain.

Q: Why does my Ledger show “Unknown App” when connecting to OKX?A: This occurs when the Ethereum or EVM app isn’t launched on the Ledger device before initiating WalletConnect. Open the Ethereum app manually on the device first.

Q: Is it safe to keep my hardware wallet connected while browsing OKX?A: No. Hardware wallets should be disconnected after completing required actions. Leaving them connected increases exposure to potential malicious dApp interactions.

Q: Does OKX store my hardware wallet’s private keys?A: Absolutely not. OKX never accesses or stores private keys. All signing operations occur locally on the hardware device, preserving cryptographic isolation.
