What Is ‘Slippage Tolerance’ and How Does a Trader Use It to Mitigate Front-Running Risk?
Slippage tolerance is the maximum percentage of price change a trader is willing to accept between the time they submit a trade and the time it is executed. By setting a very low slippage tolerance, a trader limits the potential profit a front-runner can extract from a price manipulation.
If a front-runner's preemptive trade causes the price to move beyond the set tolerance, the original transaction will automatically fail. This forces the front-runner to pay the gas fee without gaining a profit.
