XEEX Fees and Common Fees/Settings

1.XEEX Fee (No need to set) XEEX charges a 1% fee for a single settlement. There is no additional charge. For users who have questions about transaction fees, please check your gas fee and slippage settings first.

2.Gas Fee (can be set or not) Gas Fee refers to the fee that users need to pay to network validators when executing transactions or interacting with smart contracts, which is commonly known as the on-chain fee. XEEX supports three gear modes: "Normal", "Fast" and "Extreme". You can directly select the gear mode or set the gas fee freely.

3.Slippage (need to be set) Slippage refers to the maximum acceptable deviation of the number of tokens in a single transaction. For example, if the slippage is 30% when buying, if the actual tokens received are between 70% and 100%, the on-chain transaction will be successful. If the actual tokens received are less than 70%, the on-chain transaction will fail (exceeding the slippage range). The slippage limit ratio is set to ensure that you will not suffer unexpected losses due to slippage. Once the actual execution price exceeds the set slippage ratio, the transaction will be automatically canceled. When trading MEME, experienced traders will significantly increase the slippage to cope with the surge and plunge caused by token FOMO and FUD emotions, because the demand is to buy and sell quickly, and they don’t care how many transactions can actually be received. Manual buying and selling is recommended to be automatic; automatic buy/sell and other pending order operations recommend a slippage of 30%-35%; it is recommended to be 50% or more for new hot disks.

4.Anti-sandwich mode (anti-MEV sandwich attack) (need to choose whether to turn it on) The core attack method of the MEV robot (clip robot) is Sandwiching, which is the so-called sandwich attack, which is equivalent to the preemptive strategy adopted by high-frequency trading companies: in a typical sandwich attack, the MEV robot reads the incoming transaction information and preemptively executes the order, thereby pushing up the token price when you buy it.

The MEV robot detects your transaction and automatically generates a buy token transaction before the block is packaged, and the transaction fee is higher than yours, so the robot's transaction is preempted. After the robot's transaction is executed, due to the automatic market-making mechanism, the unit price of the token will be raised, and the price increase will directly affect subsequent transactions. Therefore, when it is your turn to trade, the token price has risen, and the actual number of tokens you get is not as much as when you first placed the order. This difference is also called the slippage amount. (But it is different from the normal slippage, which is a slippage caused by the clamp) After our transaction is executed, the token price will continue to rise. At this time, the robot generates another transaction to sell the lower price bought in the previous transaction, just making a profit from the difference. The two transactions generated by the robot just sandwiched our transaction, which looks like a sandwich.
