KOALAS [KoalaCoin] Token

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

Koala._getTValues(uint256) (#624-628) performs a multiplication on the result of a division:
-tFee = tAmount.div(100).mul(2) (#625)
Consider ordering multiplication before division.

Low level call in Address.sendValue(address,uint256) (#275-281):
- (success) = recipient.call{value: amount}() (#279)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#341-362):
- (success,returndata) = target.call{value: weiValue}(data) (#345)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
