In this free video of How to perform and prevent a sandwich attack We will theoretically discuss the nature of this type of attack (Sandwich Attack) in DeFi, how it is carried out, and ways to avoid it.

Front-running and sandwich attacks can be considered one of the biggest bugs in decentralized exchanges, costing users of these platforms perhaps even hundreds of thousands of dollars a day.

This video discusses how decentralized exchanges work in terms of token pricing and frontrunning.

When does a sandwich attack happen in DeFi?

Front running and sandwich attacks occur when someone becomes aware of a buy trade that moves the price of a currency by a large percentage.

The front runner, by setting a higher fee, makes his transaction confirmed before the actual buyer transaction get confirmed and immediately carries out their sale transaction after the victim purchase.

So the best way to avoid it is to make sure that our transaction does not attract the attention of the sandwich bot.

How to perform a sandwich attack?

Building a bot to implement sandwich attacks is a very complex task.

To do this, your bot needs to monitor all of your desired blockchain transactions and identify suitable opportunities.

After identifying opportunities (which themselves require very complex calculations), there is a need to create buy and sell transactions.

In fact, the bot should submit transactions in a fraction of a second that do not have excessively high fees and at the same time be confirmed very quickly.

A buy transaction and a sell transaction must be made to receive a profit.
