Where can I a depper discussion on the MEX token? The documentation on it is pretty weak, how is this anything but a farming token?

Are their gas fees on Elrond, or is the fee just captured from a % of the transaction. If their are gas fees, I am assuming those get paid in egld?

For the Mex token, is that what I need if I want a LP pair on the MEX? SO anyone looking to provide liquidity on MEX will need to buy MEX?
