## Front-Running Mechanisms

Front-running is a practice where a participant, often an exchange insider or a sophisticated bot, identifies an incoming large order and executes their own trade before the large order is processed. This allows the front-runner to profit from the expected price movement caused by the large order.

In decentralized finance, this is often done by monitoring the mempool for pending transactions and paying higher gas fees to ensure one's own trade is processed first. This practice is detrimental to retail traders who find their orders filled at less favorable prices.

Protocols are increasingly developing mechanisms to mitigate this, such as private mempools or batch auctions. Recognizing the risk of front-running is essential for anyone trading on public blockchains.

Protecting against it often involves using specialized tools or services that obfuscate trade intent.
