RHP._time (#683) is never initialized. It is used in:
- RHP._validateTransfer(address,address,uint256,bool) (#1139-1155)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Additional information: link

RHP.addLiquidity(uint256,uint256) (#1206-1220) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#1211-1219)
Ensure that all the return values of the function calls are used.

Additional information: link

RHP._approve(address,address,uint256).owner (#1086) shadows:
- Ownable.owner() (#415-417) (function)
Rename the local variables that shadow another component.

RHP.updateSellLimit(uint256) (#1315-1317) should emit an event for:
- sellLimit = limit (#1316)
Emit an event for critical parameter changes.

RHP.changeBurnWallet(address).newWallet (#918) lacks a zero-check on :
- burnWallet = newWallet (#919)
Check that the address is not zero.

RHP._validateTransfer(address,address,uint256,bool) (#1139-1155) uses timestamp for comparisons
Dangerous comparisons:
- _time[sender] + 86400 <= now (#1148)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#369-390) uses assembly
- INLINE ASM (#382-385)
Do not use evm assembly.

Different versions of Solidity is used:
- Version used: ['>=0.5.0', '^0.6.12']
- ^0.6.12 (#13)
- >=0.5.0 (#657)
Use one Solidity version.

SafeMath.mod(uint256,uint256,string) (#237-240) is never used and should be removed
Remove unused functions.

Additional information: link

RHP._previousBurnFee (#712) is set pre-construction with a non-constant function or state variable:
- _burnFee
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

Pragma version>=0.5.0 (#657) allows old versions
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 Address._functionCallWithValue(address,bytes,uint256,string) (#369-390):
- (success,returndata) = target.call{value: weiValue}(data) (#373)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable RHP._burnFee (#711) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#249)" inContext (#243-252)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable RHP._transferToExcluded(address,address,uint256).rTransferAmount (#1288) is too similar to RHP._transferStandard(address,address,uint256).tTransferAmount (#1275)
Prevent variables from having similar names.

Additional information: link

RHP.slitherConstructorVariables() (#670-1319) uses literals with too many digits:
- walletLimit = 1000000000000000000 (#715)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

RHP._sellTime (#682) is never used in RHP (#670-1319)
Remove unused state variables.

Additional information: link

RHP._tTotal (#687) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

isExcludedFromFee(address) should be declared external:
- RHP.isExcludedFromFee(address) (#1082-1084)
Use the external attribute for functions never called from the contract.
