# MEV Protection

In order to **protect** you from **slippage**, **front-running** and **sandwich** **attacks**, you can use alternatives trading modes. By default transactions are made in **Turbo Mode**. 

You can switch between differents modes : 

* :shield: **MEV/Front-run protection** : **Safeguard** you from front-run and sandwich **attacks** but is **slower**
* :brain: **Smart** : **Faster** than protection and **reduces your chances of getting attacked**
* :boom: **Turbo** : The **fastest** mode but is **attack sensible**  

To switch mode, go to your bot and do **/settings**, then click on the mode button. In the example below, it is the ":boom:Turbo mode" button. Click here until you find the mode that suits you the best.

When MEV Protection is enabled (:shield:**mode**), the bot is always **safeguarding you from attackers** but the **transactions are slower and can fail more frenquently**.

{% hint style="danger" %}
For (:shield:**MEV Protection**) and (:brain:**Smart**) modes, please ensure that you have at least **0.001 SOL of priority fees** in your settings. Otherwise, the transaction **will fail**.
