MOB [Meta Outer BSC] Token

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

MetaOuterBSC.sendETHToFee(uint256) (#370-372) sends eth to arbitrary user
Dangerous calls:
- _teamAddress.transfer(amount) (#371)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

MetaOuterBSC.openTrading() (#374-398) ignores return value by uniswapV2Router.addLiquidityETH{value: address(this).balance}(address(this),balanceOf(address(this)),0,0,owner(),block.timestamp) (#382-389)
MetaOuterBSC.openTrading() (#374-398) ignores return value by IERC20(uniswapV2Pair).approve(address(uniswapV2Router),type()(uint256).max) (#394-397)
Ensure that all the return values of the function calls are used.
