Xmeta [Xmas Meta] Token

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

Contract creator or owner is blacklisted for past scams

Xmasmeta.swapAndLiquify(uint256) (#1244-1284) sends eth to arbitrary user
Dangerous calls:
- (sent) = _devAddress.call{value: devBalance}() (#1270)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
