For withdrawals, the fee that applies on each network, either a FALKR withdrawal fee or the actual network cost, is shown before you confirm, together with the total deducted and what you receive.
Spot, Futures, TradFi and Predictions are not available yet, so no trading fees apply today; each product's fees will be published before it opens. Don't rely on illustrative prices or an assistant's estimate as a binding fee: the amounts on your confirmation screen are the ones that apply.
