WAP [WAPSWAP] Token

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

WAPSWAP._takeFee(uint256) (#835-840) ignores return value by _xcs.transferFrom(_msgSender(),FEE_ADDRESS,_fee) (#838)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Low level call in Address.sendValue(address,uint256) (#307-313):
- (success) = recipient.call{value: amount}() (#311)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#386-412):
- (success,returndata) = target.call{value: weiValue}(data) (#395)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Redundant expression "this (#119)" inContext (#109-122)
Remove redundant statements if they congest code but offer no value.

Variable WAPSWAP.FEE_ADDRESS (#751) is too similar to WAPSWAP.changeFeeAddress(address)._feeAddress (#810)
Prevent variables from having similar names.

WAPSWAP.validChain(string).i (#875) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
