Step 1:

Connect your Metamask wallet. If you are not using Metamask you can skip this step

Step 4 (If you are not using Metamask):

Within four minutes your ETH will be in the same wallet on the Arbitrum One network. You can see the receipt of your bridge transactions by clicking the [Track] buttons. The top one will lead you to the Ethereum Blockchain explorer where you can see a receipt of the transaction where you sent your funds into the bridge. The bottom [Track] button shows the transaction receipt of the bridge sending your ETH back to your wallet on the Arbitrum One network. Your transaction is now complete!

Step 4 (If you are using Metamask):
Press the [Send (Metamask)] button. A preview of your transaction will pop up. Review the information in the preview and press the [Send] button.

This will cause Metamask to pop up with the final confirm window.

Press [Confirm] and your transaction will begin. Another window will pop up to track the transaction.

When two ticks are displayed, the transaction is complete.

Then press [Switch Network] to confirm it in your Metamask.
Finally press [Add Asset to Metamask] to start tracking your ETH balance on the Arbitrum One Network. If you do not click this button, your assets may not be visible in the Metamask wallet.

The bridging process is now complete.
