Don't Let Your Trading Become the Recipe of Someone's Sandwich

In a sandwich attack, the searchers/attackers 'sandwich' the victim's transactions between their own two transactions, called the front-run and the back-run. The victimized users suffer an implicit loss when these attackers reorder the transactions to benefit themselves.
