Front Running Vulnerability

Front running vulnerability is a flaw in transaction processing where a malicious actor can observe a pending transaction and insert their own transaction before it, profiting at the original user's expense. This is common in decentralized exchanges where the mempool is public and visible to all participants.

By paying a higher fee or using specialized bots, front-runners can ensure their trade is executed first, often causing the original user to receive a worse price. This practice is a major concern for user protection and market fairness in DeFi.

Developers attempt to mitigate this through techniques like transaction encryption, commit-reveal schemes, or private mempools. Understanding this vulnerability is essential for any user engaging in significant trading on decentralized platforms.
