Before you start

All set? Great, let’s dive in.

Install the Ethereum (ETH) app on your Ledger device

  1. Connect your Ledger device and unlock it.
  2. In the Ledger Live app, navigate to My Ledger.
  3. Confirm that you allow My Ledger to access your device. You can do that by clicking both buttons on your device simultaneously. 
  4. Go back to Ledger Live. In My Ledger, head over to App catalog and search for Ethereum (ETH).
  5. Click Install.

The Ethereum (ETH) app is installed on your Ledger device. Now let’s bridge some ETH to Arbitrum.

Add an Arbitrum account to Ledger Live

  1. In the left sidebar menu, go to Accounts.
  2. Click Add account.
  3. Choose Arbitrum (ETH) from the drop-down list.
  4. Click Continue.
  5. Connect your device to the Ledger Live app and unlock it.
  6. Open the Ethereum (ETH) app on your device.
  7. Click Add account.

Bridge ETH or ERC20 from your Ethereum to your Arbitrum account

  1. Head to the Discover section and select Squid.

  2. From the menu, choose the type of cryptocurrency you want to bridge (ETH, ERC20 token), specify the amount, and select Ethereum as the source network and Arbitrum as the destination network.

  3. Click Submit.

  4. Next, select the desired transaction fee and click Continue.

     Please note, the higher the fee, the quicker your transaction will be processed. However, the amount you specify is the maximum fee you're willing to pay, not necessarily the amount you will be charged. Any unused gas fee will be refunded back to your Ethereum account.

  5. Review your transaction one final time. If everything looks correct, press Continue.

  6. Ledger Live will automatically install the Squid app on your Ledger device. After the installation is complete, open the Squid app on your device by pressing both buttons simultaneously.

    1. On your Ledger device, review the transaction details, including the fees, one final time. If everything appears correct, navigate to the Accept and Send screen and press both buttons simultaneously to sign the transaction.

      All done! After your transaction is confirmed on the Ethereum blockchain and processed via the Squid bridge, your tokens will appear in your Arbitrum account. Remember, this could take a few minutes. If you'd like to track your transaction, simply click the View button.

        Squid also enables you to bridge funds across numerous other EVM chains, including Optimism, Polygon, Avalanche, Binance Smart Chain, and many more!
