Token seems to be a scam (type: honeypot scam).

Reentrancy in XavierMusk._transfer(address,address,uint256) (#328-347):
External calls:
- swapBack() (#340)
- router.swapExactTokensForETHSupportingFeeOnTransferTokens(amountToSwap,0,path,address(this),block.timestamp) (#389-395)

Apply the check-effects-interactions pattern.

XavierMusk.swapForToken(address,address) (#421-424) ignores return value by IBEP20(token).transfer(receiver,IBEP20(token).balanceOf(address(this))) (#423)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

XavierMusk.swapBack() (#380-413) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,marketingFeeReceiver,block.timestamp) (#403-410)
Ensure that all the return values of the function calls are used.

XavierMusk._approve(address,address,uint256).owner (#304) shadows:
- Ownable.owner() (#141-143) (function)
Rename the local variables that shadow another component.

XavierMusk.setSwapBackSettings(uint256) (#449-452) should emit an event for:
- swapThreshold = _amount (#451)
Emit an event for critical parameter changes.

XavierMusk.TransferBNBsOutfromContract(uint256,address).receiver (#415) lacks a zero-check on :
- receiver.transfer(amount) (#419)
Check that the address is not zero.

XavierMusk.transferFrom(address,address,uint256) (#318-327) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(startTime > 0 || isFeeExempt[sender],Trading not open) (#322)
- startTime == 0 && recipient == pair (#323)
XavierMusk._transfer(address,address,uint256) (#328-347) uses timestamp for comparisons
Dangerous comparisons:
- sender == pair && (block.timestamp - startTime <= botTime) && ! isFeeExempt[recipient] (#332)
Avoid relying on block.timestamp.

XavierMusk.swapThreshold (#252) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 2000
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
