You can see a list of ERC-20 tokens that are added to each new Guarda wallet by default in your list of currencies under Ethereum > Tokens. If you would like to operate with tokens that aren’t already listed, you can always add them on your own.
Select Add Custom ERC20 under the list of tokens and enter the token’s smart contract address.
You can find the smart contract address by finding the token on etherscan.io. It will be listed on the token’s page under Contract.
The token will then appear at the end of your list of tokens.
