Frequently Asked Questions
How does connecting a hardware wallet improve security?
Connecting a hardware wallet like Keystone to OKX Wallet significantly enhances security because your private keys never leave the cold storage device. All transactions must be physically verified and signed on the hardware wallet itself, protecting your assets from online threats such as phishing attacks or malware.
Can I connect multiple Keystone wallets or accounts to one OKX Wallet?
Yes, the OKX Wallet supports connecting multiple hardware wallet accounts. You can simply repeat the import process for each account you wish to manage. This allows you to organize different portfolios or assets within a single OKX Wallet interface.
What should I do if the QR code scan fails?
First, ensure your Keystone device's screen and your phone's camera lens are clean. Check that both devices have a stable connection and that you are in a well-lit environment. If the problem persists, try closing and reopening both the OKX app and your Keystone wallet before restarting the process.
Which EVM-compatible chains are supported?
You can manage assets on all major EVM chains, including Ethereum, Polygon, Arbitrum, Optimism, and BNB Smart Chain. The specific chains available are those natively supported by your Keystone hardware wallet.
Is there a fee for connecting the wallets?
No, connecting your Keystone hardware wallet to the OKX Web3 Wallet is completely free. OKX does not charge any fees for the integration process itself. Standard network gas fees will apply for any on-chain transactions you choose to execute.
My transaction is pending. What does this mean?
A pending transaction typically means it is waiting to be confirmed and added to the blockchain. This can sometimes take a few minutes depending on network congestion. You can always check the status of your transaction using a blockchain explorer by looking up the transaction ID (hash).
