## Front-Running Risks

Front-Running Risks refer to the possibility that a trader or a validator observes a pending transaction in the mempool and executes their own transaction ahead of it to profit at the expense of the original trader. This is a common concern in decentralized exchanges, where transactions are public before they are included in a block.

By paying a higher gas fee or leveraging a validator's power, an attacker can manipulate the price for the victim's trade, causing slippage or total failure. This practice is a form of maximal extractable value that challenges the fairness of decentralized markets.

Mitigating these risks requires using privacy-preserving technologies, such as encrypted mempools or decentralized sequencing, to protect transaction intent. It is a critical area of research for ensuring the integrity and security of programmable money.
