Agama currently takes only 10000 Satoshis or 0.0001 Kmd as a fee when you claim your rewards or when you make a transaction.

This value will be calculated when you are about to make a transaction and you will be able to verify it inside the Send tab inside Agama as showed below.

You will always be able to see the current amount and the calculated fee been shown before you send a transaction using Agama.

As a side note we have to let you know as a user that we don't control Exchange fees because they are controlled by third party subjects outside of our native applications.
