The Simpsons is a deflationary token. It's created on Binance Smart Chain as it's fast and cheap. Goal of the token is to mint The Simpsons NFT's and distribute the profits among holders and charity foundations.
Later, we will implement it's own NFT Marketplace. With the support of our community and hard work of developers, we will make Simpsons the best NFT project on Smart Chain.

Ensure that all the return values of the function calls are used.

Rename the local variables that shadow another component.

TheSimpsons.setMaxTxPercent(uint256) (#907-911) should emit an event for:
- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#908-910)
Emit an event for critical parameter changes.

Ownable.unlock() (#482-487) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#484)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#380-401) uses assembly
- INLINE ASM (#393-396)
Do not use evm assembly.
Additional information: link
SafeMath.mod(uint256,uint256,string) (#248-251) is never used and should be removed
Remove unused functions.
Additional information: link
TheSimpsons._previousLiquidityFee (#730) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#380-401):
- (success,returndata) = target.call{value: weiValue}(data) (#384)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable TheSimpsons._maxTxAmount (#738) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#260)" inContext (#254-263)
Remove redundant statements if they congest code but offer no value.
Additional information: link
Variable TheSimpsons.reflectionFromToken(uint256,bool).rTransferAmount (#847) is too similar to TheSimpsons._getValues(uint256).tTransferAmount (#927)
Prevent variables from having similar names.
Additional information: link
TheSimpsons.slitherConstructorVariables() (#704-1163) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 500000 * 10 ** 6 * 10 ** 9 (#739)
Use: Ether suffix, Time suffix, or The scientific notation
Additional information: link
TheSimpsons.numTokensSellToAddToLiquidity (#739) should be constant
Add the constant attributes to state variables that never change.
Additional information: link
isExcludedFromFee(address) should be declared external:
- TheSimpsons.isExcludedFromFee(address) (#999-1001)
Use the external attribute for functions never called from the contract.
