For the Swap and Transfer feature:
You don’t have to pay KyberSwap any transaction fees for basic token swaps and transfer. However, as KyberSwap operates on-chain, you will have to pay gas fees for the Ethereum network.
Gas fee highly depends on the network congestion at the moment of your transaction, so be sure to consider it when making your decisions. This gas fee must be paid in ETH and it goes to the miners on the Ethereum blockchain, KyberSwap does not collect anything.
For the Limit Order feature:
KyberSwap has 2 tiers fee structure:
0.5% of transaction amount if trading amount <= 5 ETH
0.2% of transaction amount if trading amount > 5 ETH
Additionally, you don’t have to pay a gas fee for Limit Order, the trading fee already includes gas fees.
