## Front-Running Detection

Front-running detection involves monitoring order books and mempools to identify instances where traders or validators capitalize on non-public information about pending transactions. In decentralized exchanges, this often manifests as sandwich attacks where an attacker inserts a transaction before and after a victim's trade to profit from the resulting price slippage.

Detection algorithms analyze transaction ordering within blocks to flag deviations from standard execution sequences. By identifying patterns of predictive ordering, auditors can assess if miners or validators are exploiting their position to disadvantage users.

This process is essential for securing trust in automated market makers and order book protocols. Effective detection helps developers refine protocol physics to minimize the impact of information asymmetry.

It ensures that the sequence of trade execution remains fair and resistant to adversarial manipulation.
