# Settings

## Reset Trading Layout

Since the Trading Layout is fully customizable, you may accidentally delete a panel or simply want to restore the default layout. This can be done at any time by clearing your browser data or manually from the Settings.

## Transaction Priority Fee

DefiTuna is built on top of the Solana network as a Defi protocol. As such, any interaction with our platform, including lending pool activity and opening/closing positions, requires direct communication with Solana validators. 

Under normal conditions, our default fee settings are sufficient for smooth operation. However, during periods of high network congestion, you may need to apply higher priority fees to ensure your transactions are processed in a timely manner.

In the navigation bar, click the cog icon. Under **Priority Fee**, select either one of our pre-set options (e.g., Auto) or define a custom fee.

* Selecting "**Auto**" allows the protocol to apply a fee above average based on current network activity.
* For greater reliability during congestion, you can boost fees up to **5x** or **10x** the average cost.
* To avoid overpaying, we've implemented a **Max Fee Cap**. This feature protects users from accidentally setting fees that are too high.

Don't forget to lower your fee settings once congestion eases!

## Change RPC

We currently support **Triton**, **Helius** and **Custom** RPCs (Remote Procedure Calls).

To ensure smooth interaction with DeFiTuna, we recommend selecting the RPC endpoint with the lowest response time (in milliseconds). This will help reduce latency and improve the overall responsiveness of your experience.

To change the RPC, click the cog icon in the navigation bar, then open the dropdown under **RPC**, select your preferred RPC or enter your custom RPC, and click **Save Changes**.
