Coinomi natively supports hundreds tokens. Please consult this article if you want to add a contract not in the native list of tokens, and this one if you want to add a non-ERC20 (generic) contract.

The most known tokens are already natively supported in Coinomi and you can add them to your favorites in just a few taps. 

1. Add an ETHEREUM wallet if you haven't already done so.

2. Go to your ETHEREUM wallet, and swipe two screens to the right to get to dApps page.

3. Scroll down to the token you want to add to Coinomi (or search for its name). Hint: type ERC20 to filter out non-ERC20 tokens.

4. From the token overview page that appears, click on the + icon in the top right of the screen, to add this wallet to your favorites. 

You will now be able to see this token's wallet in your main Coinomi Overview page. 

The added wallets can also be seen when you press the three horizontal lines icon (top left). It will be in a sub-list under ETHEREUM.

Alternatively, as of version 1.8, you can follow the steps below:

1. Open the left side menu and select "+ tokens"

2. Select Ethereum as the type of token

3. Tap to select all tokens you want to add, then "finish" to add them all to favorites.

You can delete an added wallet from the overview page just like the other coins' wallets, by long pressing the wallet for 2 seconds and clicking on the "Trash" icon that appears on the top right of the screen.
