FSV [FileSystemVideo] Token

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

Contract creator or owner is blacklisted for past scams

Contract ownership is not renounced (belongs to a wallet)

Redundant expression "this (#123)" inContext (#117-127)
Remove redundant statements if they congest code but offer no value.

Variable CosmosToken.setPairAddr(address)._pairAddress (#956) is too similar to ERC20.paireAddress (#169)
Variable CosmosToken.setFeeAddressAndPercent2(address,uint256,uint256)._denominator (#949) is too similar to ERC20.tDenominator (#167)
Prevent variables from having similar names.

CosmosToken.burnToken(uint256,string,string).fee (#925) is a local variable never initialized
ERC20._transfer(address,address,uint256).fee (#350) 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.

CosmosToken.constructor(string,string,uint8) (#830-833) ignores return value by EnumerableSet.add(_minters,_msgSender()) (#832)
Ensure that all the return values of the function calls are used.

Pragma version^0.8.0 (#5) allows old versions
solc-0.8.1 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
