SAFE [SpaceXliFe] Token

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

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

SpaceXliFe._swapContractToken(bool) (SpaceXliFe.sol#266-305) sends eth to arbitrary user
Dangerous calls:
- (sent) = marketingWallet.call{value: address(this).balance}() (SpaceXliFe.sol#303)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

SpaceXliFe._swapContractToken(bool) (SpaceXliFe.sol#266-305) performs a multiplication on the result of a division:
-tokenToSwap = _balances[_pancakePairAddress] * swapTreshold / 1000 (SpaceXliFe.sol#270)
-tokenForLiquidity = (tokenToSwap * liquidityTax) / totalTax (SpaceXliFe.sol#283-285)
SpaceXliFe._swapContractToken(bool) (SpaceXliFe.sol#266-305) performs a multiplication on the result of a division:
-LiqHalf = tokenForLiquidity / 2 (SpaceXliFe.sol#289)
