KyberSwap is a fully onchain service. Everyone who creates transactions on the blockchain will need to pay network fees associated with their transactions. These fees vary depending on
- The network being used
- Network congestion at the time
- Complexity of the smart contract transaction being executed
Note: Network fees will apply for transactions that are successfully broadcast to the blockchain regardless of whether or not swaps or liquidity transactions are successfully executed (e.g. in the case of a swap transaction failing due to not enough slippage tolerance). These gas fees are paid to blockchain miners and not to KyberSwap, and so no requests for refunds of gas fees will be entertained.
Fees for Swaps
Positive Slippage Surplus
KyberSwap collects positive slippage surplus that does not affect the user outputs. This surplus is collected at this address: 0x4f82e73EDb06d29Ff62C91EC8f5Ff06571bdeb29
Smaller Chain Fees
To help offset the costs of operating on smaller chains, swap fees are charged for trades on the following chains:
The swap fee charged to users is 0.04% for trades between two stablecoins and 0.1% for swaps involving any non-stablecoin token.
Liquidity Provider Fees
Liquidity Providers are allowed to set fees on their liquidity pools, and traders who choose to use these pools to perform swaps will need to pay trading fees to the LP, along with any associated network fees.
It should be noted that of these Trading Fees collected by LPs, 10% goes to KyberSwap’s governance DAO, KyberDAO.
