To execute a DeFi swap, you are going to pay the network transaction (gas) fee. It's a fee that is required by the chain to conduct a transaction on the blockchain successfully.
Depending on the fee amount, your transaction will be prioritized by the miners/validators. In CoinStats, you can choose three options for your transaction speed: Standard, Fast and Instant.
Depending on the gas price and network load, fee amount and time are changing.
In essence, gas fees are paid in the network's native currency, i.e., ether for the Ethereum network. CoinStats charges an extra 0.5% DeFi Swap Fee.
