After clicking the "Send" button, you will see the Send Asset screen. Here you will select an asset from the drop down, set an amount, and paste in an address. You will also see the estimated network fees, which Tally gets from BlockNative. You can edit the transaction settings to set your preferred Network Fees by clicking on the gear icon to set speed/priority. After clicking "Send", you will get a review screen with an overview of the transaction, where you can either "Sign" or "Reject".
