What Happens to a Transaction If the Price Movement Exceeds the Set Slippage Tolerance?

If the price movement during the time between submitting a transaction and its execution exceeds the user's set slippage tolerance, the transaction will automatically revert or fail. The smart contract, which governs the trade on the DEX, includes a check to ensure the executed price is within the acceptable slippage range.

While the trade fails, the user will still incur the gas fee paid for the failed transaction, as the network resources were consumed attempting the execution.
