HelloTiger._tokenTransfer(address,address,uint256,bool) (#438-480) performs a multiplication on the result of a division:
-_rOwned[recipient] = _rOwned[recipient].add(rAmount.div(100).mul(recipientRate)) (#476-478)
HelloTiger._tokenTransfer(address,address,uint256,bool) (#438-480) performs a multiplication on the result of a division:
-Transfer(sender,recipient,tAmount.div(100).mul(recipientRate)) (#479)
Consider ordering multiplication before division.

HelloTiger._tokenTransfer(address,address,uint256,bool).rate (#448) 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.

HelloTiger.allowance(address,address).owner (#297) shadows:
- Ownable.owner() (#92-94) (function)
HelloTiger._approve(address,address,uint256).owner (#409) shadows:
- Ownable.owner() (#92-94) (function)
Rename the local variables that shadow another component.

Ownable.changeOwner(address) (#104-106) should emit an event for:
- _owner = newOwner (#105)
Emit an event for critical parameter changes.

Additional information: link

Ownable.changeOwner(address).newOwner (#104) lacks a zero-check on :
- _owner = newOwner (#105)
HelloTiger.constructor(address,address).chainFunAddress (#253) lacks a zero-check on :
- _chainFunAddress = chainFunAddress (#262)
HelloTiger.changeRouter(address).router (#499) lacks a zero-check on :
- uniswapV2Pair = router (#500)
Check that the address is not zero.

Additional information: link

HelloTiger.uniswapV2Pair (#249) is set pre-construction with a non-constant function or state variable:
- _destroyAddress
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

Variable Ownable._owner (#87) is not in mixedCase
Variable HelloTiger._tTotalFeeMax (#238) is not in mixedCase
Follow the Solidity naming convention.

HelloTiger.slitherConstructorVariables() (#227-503) uses literals with too many digits:
- _destroyAddress = address(0x000000000000000000000000000000000000dEaD) (#245-246)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

HelloTiger._tOwned (#231) is never used in HelloTiger (#227-503)
Remove unused state variables.

Additional information: link

HelloTiger._destroyAddress (#245-246) should be constant
Add the constant attributes to state variables that never change.
