Thanks for reaching out! You can add a custom token to an EVM account from the Accounts screen. Find the account you want to add AERO to, and then click 'Manage Account' on the right side; you'll see the option to import a custom token, and this is where you'll be able to add AERO. From that point on, NuFi will search for this token too when it loads your wallet's contents, and it will be displayed in your wallet if you have any. If you need any help, please open a support ticket at https://support.nu.fi/support/tickets/new
