You can add the Ethereum address to your account by connecting with MetaMask.
It's recommended to create a Vatom Account with your email or phone number before adding your Metamask Account.
To add Metamask ETH address, open Vatom Wallet in a Web3 compatible Browser like Google Chrome.
On Mobile, load wallet.vatom.com in the Metamask in-app browser to add your ETH wallet to Vatom.
1. Open Profile by clicking the icon image in the top-right of the Vatom Wallet.
2. Click on "Manage your Account"
3. This will open a new tab or a window - "Identities". Click on "+ Add"
4. Of all the available options, please select "Add from MetaMask"
Follow the instructions to "Connect" and "Sign" on your MetaMask window.
Please note that you are only signing the message to finish authentication. There are no funds being transferred at this time. You do NOT need any funds to finish this step.
Now you should see your Etherium address on the list of the "Identities" page.
You can now safely close the "Identities" page and return back the tab/window with the wallet. In your wallet, you can filter your wallet contents by Custodial Address to show only your Polygon and ETH objects.
