Pyroworld.addLiquidity(uint256,uint256) (#770-784) sends eth to arbitrary user
Dangerous calls:
- (amountToken,amountETH) = uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#775-782)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

Pyroworld.swapAndLiquify(uint256) (#709-750) performs a multiplication on the result of a division:
-bnbForLottery = newBalance / 10000 * _percentageOfLiquidityForLottery (#723)
Consider ordering multiplication before division.

Pyroworld._approve(address,address,uint256).owner (#644) shadows:
- Ownable.owner() (#40-42) (function)
Rename the local variables that shadow another component.

Pyroworld.setLiquidityPercentages(uint256,uint256,uint256,uint256,uint256) (#558-564) should emit an event for:

- _percentageOfLiquidityForCharity = charityFee (#561)
- _percentageOfLiquidityForBuyback = buybackFee (#562)
- _percentageOfLiquidityForLottery = lotteryFee (#563)
Emit an event for critical parameter changes.

Pyroworld.setUniswapPair(address).p (#578) lacks a zero-check on :
- uniswapV2Pair = p (#579)

Ownable.unlock() (#71-76) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is still locked) (#73)
Avoid relying on block.timestamp.

Context._msgData() (#10-13) is never used and should be removed
Remove unused functions.

Additional information: link

Pyroworld._antiWhaleThreshold (#348) is set pre-construction with a non-constant function or state variable:
- _tTotal * 75 / 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.

Additional information: link

solc-0.8.5 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.

Additional information: link

Variable Pyroworld._antiWhaleThreshold (#348) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#11)" inContext (#5-14)
Remove redundant statements if they congest code but offer no value.

Variable Pyroworld._getRValues(uint256,uint256,uint256,uint256).rTransferAmount (#603) is too similar to Pyroworld._transferStandard(address,address,uint256).tTransferAmount (#815)
Prevent variables from having similar names.

Pyroworld.slitherConstructorConstantVariables() (#283-835) uses literals with too many digits:
- _burnAddress = 0x000000000000000000000000000000000000dEaD (#301)
Use: Ether suffix, Time suffix, or The scientific notation

Pyroworld._tTotal (#304) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

isExcludedFromFee(address) should be declared external:
- Pyroworld.isExcludedFromFee(address) (#640-642)
Use the external attribute for functions never called from the contract.
