SneakersVerse.withdrawToken(address,uint256) (#414-417) ignores return value by tokenContract.transfer(msg.sender,_amount) (#416)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.


Contract ownership is not renounced (belongs to a wallet)

SneakersVerse.addWhiteList(address[]).i (#424) 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.

SneakersVerse.allowance(address,address).owner (#253) shadows:
- Ownable.owner() (#56-58) (function)
SneakersVerse._approve(address,address,uint256).owner (#317) shadows:
- Ownable.owner() (#56-58) (function)
Rename the local variables that shadow another component.

SneakersVerse._redisFee (#182) is set pre-construction with a non-constant function or state variable:
- _redisFeeOnSell
SneakersVerse._taxFee (#183) is set pre-construction with a non-constant function or state variable:
- _taxFeeOnSell
SneakersVerse._previousredisFee (#185) is set pre-construction with a non-constant function or state variable:
- _redisFee
SneakersVerse._previoustaxFee (#186) is set pre-construction with a non-constant function or state variable:
- _taxFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Pragma version^0.8.9 (#9) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 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.
