Step-by-Step Guide: Bridge BTC to Bitlayer Using OKX Wallet

Step 1: Access the Official Bitlayer Bridge

Open your browser and navigate to the official Bitlayer website:
👉 https://bitlayer.org

Once loaded, click on [Bridge & Earn] in the navigation menu to access the cross-chain bridge interface.

Step 2: Connect Your Bitcoin Wallet

Click the [Connect Wallet] button. From the options available, select OKX Wallet (or another supported BTC wallet like Unisat).

After selecting, confirm the connection in your wallet extension. You should see a confirmation message indicating that your wallet is successfully linked.

Step 3: Enter Transfer Amount

Input the amount of BTC you wish to transfer to Bitlayer. Keep these rules in mind:

For example:

Step 4: Connect Your EVM-Compatible Wallet

Since Bitlayer supports EVM-based dApps, you must also connect an EVM wallet to receive assets on the L2 network.

Click [Connect Wallet] again and choose one of the following:

In this example, we select OKX Wallet again. Click [Connect] and approve the request in your wallet extension.

When successful, you’ll see a confirmation screen showing both wallets connected.

Step 5: Initiate the Transfer

With both wallets connected and the correct amount entered, click the [Transfer] button.

Your OKX Wallet extension will pop up with a transaction signature request. Review all details carefully and click [Confirm] to proceed.

Step 6: Monitor Transaction Status

After signing, a transaction receipt will appear within the Bitlayer bridge interface.

You'll see the status marked as “Pending”, which means your cross-chain transaction is being processed on-chain. Processing time varies depending on network congestion but typically takes just a few minutes.

Once completed, the status will change to “Completed”, and an arrow will point to your BTC address on Bitlayer — this is your new address within the L2 ecosystem.

🎉 Congratulations! You’ve successfully bridged BTC to Bitlayer.
