What is Backrunning? — MEV Attacks Explained
Backrunning is a specific type of MEV that causes traders to miss out on potential profit opportunities from their trades. It involves strategically executing a transaction immediately after a high-value transaction to capitalize on arbitrage opportunities left over. While backrunning is considered the least harmful type of MEV, it can be combined with other attacks to create the worst kind of MEV, such as sandwich attacks. CoW Swap eliminates backrunning opportunities through its delegated trading mechanism, and MEV Blocker offers rebates for any backrunning opportunities created when trading on Ethereum.
