LevelUpGaming.tokenSwap(bool) (#661-721) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(developerFeeReceiver).call{gas: 50000,value: amountBNBdeveloper}() (#705)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

LevelUpGaming.emergencyWithdraw(uint256,address,address) (#599-603) ignores return value by token.transfer(_receiver,_amount) (#602)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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


Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

LevelUpGaming.tokenSwap(bool).tmpSuccess (#705) is written in both
(tmpSuccess) = address(developerFeeReceiver).call{gas: 50000,value: amountBNBdeveloper}() (#705)
tmpSuccess = false (#707)
Fix or remove the writes.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.


Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.


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.

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.

Low level call in LevelUpGaming.tokenSwap(bool) (#661-721):
- (tmpSuccess) = address(developerFeeReceiver).call{gas: 50000,value: amountBNBdeveloper}() (#705)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable LevelUpGaming._isCheater (#337) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

LevelUpGaming.takeFee(address,address,uint256) (#620-653) performs a multiplication on the result of a division:
-_rewardsFee = _rewardsFeeCheater * sellMulti.div(1000) (#638)
Consider ordering multiplication before division.

Additional information: link

LevelUpGaming.tokenSwap(bool).dynamicLiquidityFee (#662) 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.

LevelUpGaming.tokenSwap(bool) (#661-721) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (#711-718)
Ensure that all the return values of the function calls are used.

LevelUpGaming.setTargetLiquidity(uint256,uint256) (#585-588) should emit an event for:
- targetLiquidity = _target (#586)
- targetLiquidityDenominator = _denominator (#587)
Emit an event for critical parameter changes.

LevelUpGaming.setRewardsAddress(address)._reward (#594) lacks a zero-check on :
- prizePoolHolder = _reward (#595)
Check that the address is not zero.

LevelUpGaming.claim(uint256,uint256,bytes32[]) (#437-451) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(prizePoolWallet.getClaimCooldownTimer(msg.sender) < block.timestamp,Please wait for cooldown between claims) (#445)
Avoid relying on block.timestamp.

LevelUpGaming._transferFrom(address,address,uint256) (#740-770) compares to a boolean constant:
-require(bool)(tradingIsEnabled == true || sender == owner || recipient == owner) (#743)
Remove the equality to the boolean constant.

Additional information: link

LevelUpGaming.swapThreshold (#371) is set pre-construction with a non-constant function or state variable:
- _totalSupply * 10 / 10000
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.

Variable IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#162) is too similar to IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#163)
Prevent variables from having similar names.

LevelUpGaming.slitherConstructorVariables() (#314-784) uses literals with too many digits:

- LevelUpGaming.checkIsCheater(address) (#605-607)
Use the external attribute for functions never called from the contract.
