## Front-Running Risk

Front-running risk is the danger that a trader's transaction will be observed in the mempool and exploited by another party before it is confirmed on the blockchain. This is a common issue in decentralized exchanges where miners or sophisticated bots can see pending transactions and place their own transactions with higher gas fees to get ahead.

This can lead to worse execution prices for the original trader. It is a form of MEV, or Maximal Extractable Value.

To mitigate this risk, traders use private transaction relayers or flashbots that bypass the public mempool. Understanding front-running is essential for secure trading in DeFi.

It is a direct consequence of the transparency of public blockchains. Protecting against it is a key challenge for both users and developers of decentralized applications.
