## Priority Fee Options&#x20;

**Standard:** 0.002 SOL (\~10 seconds for transaction completion). Faster: 0.006 SOL (\~4 seconds for transaction completion). Fast: 0.012 SOL (\~2 seconds for transaction completion).

You can manually set a custom priority fee too, maximum 0.2 SOL.

## Slippage&#x20;

Slippage is the maximum price difference you're okay with during a transaction. For example, if you set 30% slippage and the token price is $1, it might be bought or sold at up to $1.30 or as low as $0.70 if no closer price is available.

## MEV Attack Protection&#x20;

Toggle switch to enable or disable protection against MEV (Miner Extractable Value) attacks during transactions by routing using Jito.

MEV attacks are when bots front-run, back-run, or sandwich your trades, taking your profits by exploiting the block producer control (prioritizing their transactions over yours in the same block).

## Default Trade Settings&#x20;

Toggle switch to use these current trade settings as the default for all future buy/sell transactions.
