METAD [META WORLD] Token

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

METAWORLD.swapAndLiquify(uint256) (#1152-1203) sends eth to arbitrary user
Dangerous calls:
- (sent,data) = _charityAddress.call{value: charityBalance}() (#1182)
- (sent,data) = _marketingDevAddress.call{value: marketingBalance}() (#1190)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

METAWORLD._tokenTransfer(address,address,uint256,bool) (#1241-1267) contains a tautology or contradiction:
- balanceOf(sender).sub(amount).sub(receiedAmount) < 0 (#1244)
Fix the incorrect comparison by changing the value type or the comparison.
