MetaBlackout.swap() (#935-985) sends eth to arbitrary user
Dangerous calls:
- address(developmentWallet).transfer(amountBNBDevelopment) (#974)
- address(developmentWallet2).transfer(amountBNBDevelopment) (#975)
MetaBlackout.addLiquidity(uint256,uint256) (#987-999) sends eth to arbitrary user
Dangerous calls:
- router.addLiquidityETH{value: bnbAmountToLiquify}(address(this),tokenAmountToLiquify,0,0,owner(),block.timestamp) (#989-996)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains
Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
MetaBlackout._reflectionTotal (#665) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tokenTotal))
MetaBlackout.maxTxAmount (#687) is set pre-construction with a non-constant function or state variable:
- _tokenTotal.mul(10).div(1000)
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.
