## Sandwich Attack Prevention

Sandwich attack prevention involves technical strategies to protect users from predatory trading where an attacker observes a pending transaction in the mempool and executes their own trades before and after it to manipulate the price. By front-running the user's trade, the attacker forces the user to execute at a worse price, then profits by reversing the trade on the other side of the user's transaction.

Prevention methods include using private transaction relays that bypass the public mempool, implementing slippage limits that automatically cancel trades if the price moves beyond a certain threshold, and utilizing protocols that bundle transactions to ensure atomic execution. Additionally, some decentralized exchanges have introduced features that randomize transaction ordering or introduce latency to discourage front-running.

Protecting against sandwich attacks is essential for maintaining a fair and equitable trading environment, especially for retail users who may not have the resources to defend against sophisticated bot-driven strategies. It remains a key focus area for developers aiming to improve the user experience in decentralized markets.
