How Does a DEX Prevent a Sandwich Attack Using a TWAP Mechanism?
A sandwich attack involves an MEV bot placing an order before (front-run) and after (back-run) a victim's transaction to profit from the price movement. If the DEX uses a TWAP for its price feed, the price used for the victim's trade is an average over time, making it resistant to the immediate, single-block price manipulation required for a sandwich attack.
