Gas is a fee Ethereum blockchain users pay to compensate the network for facilitating requests. You must hold ETH in your wallet in order to pay for gas. Since Totle is built on the Ethereum blockchain, gas is required to complete swaps.
Totle's method for finding the best pricing available for your assets factors in the price of gas. Please use the recommended amount of gas set by Totle or it is possible that your transaction will fail.
Up to 50% of the gas you spend with Totle can be refunded to you due to our integration of GasToken.
