Price impact is how much your own swap moves the price. Your order buys from, or sells into, the people offering the best prices first. A bigger order has to go deeper down that list, so the average price you get is a little worse. We show it as a percentage before you confirm. Small swaps barely move the price; a large one on a quiet market can move it a lot, and we ask you to confirm when it is 3% or more.

A flat 0.50% fee, taken from the coin you receive. The amount is shown in the price summary before you confirm, and again on the result screen after. There are no other charges on a swap.

That is what the slippage allowance (the sliders icon on the card, 1% by default) is for. It is the most the price may move against you between your quote and the trade. If it moves further, the swap is cancelled instead and nothing is spent. The "Minimum received" figure shows the least you would end up with at the limit.
