LANDOFDOGES.rescueToken(address,uint256) (#451-453) ignores return value by IBEP20(_token).transfer(owner(),_amount) (#452)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.

LANDOFDOGES.swapAndLiquify(uint256) (#339-365) ignores return value by address(dev).call{gas: 30000,value: amountBNBdev}() (#360)
Ensure that the return value of a low-level call is checked or logged.

Additional information: link

LANDOFDOGES.addLiquidity(uint256,uint256).e (#402) 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.

LANDOFDOGES.addLiquidity(uint256,uint256) (#389-407) ignores return value by router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp.add(300)) (#395-406)
Ensure that all the return values of the function calls are used.

LANDOFDOGES.setSwapBackSettings(bool,uint256) (#438-441) should emit an event for:
- swapThreshold = _amount (#440)
Emit an event for critical parameter changes.

Additional information: link

LANDOFDOGES.setdevWallet(address)._dev (#434) lacks a zero-check on :
- dev = _dev (#435)
Check that the address is not zero.

Variable 'LANDOFDOGES.addLiquidity(uint256,uint256).e (#402)' in LANDOFDOGES.addLiquidity(uint256,uint256) (#389-407) potentially used before declaration: AddLiquidityFailed(string(abi.encodePacked(AddLiquidityFailed failed with error ,e))) (#403)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

LANDOFDOGES.canSwap() (#303-305) is never used and should be removed
Remove unused functions.

Additional information: link

LANDOFDOGES.swapThreshold (#208) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 5000
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.

solc-0.8.6 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 LANDOFDOGES.swapAndLiquify(uint256) (#339-365):
- address(dev).call{gas: 30000,value: amountBNBdev}() (#360)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable LANDOFDOGES.ZERO (#461) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#53)" inContext (#47-56)
Remove redundant statements if they congest code but offer no value.

Variable IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#138) is too similar to IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#139)
Prevent variables from having similar names.

LANDOFDOGES.slitherConstructorVariables() (#179-471) uses literals with too many digits:
- ZERO = 0x0000000000000000000000000000000000000000 (#461)
Use: Ether suffix, Time suffix, or The scientific notation

LANDOFDOGES.feeDenominator (#199) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

getCirculatingSupply() should be declared external:
- LANDOFDOGES.getCirculatingSupply() (#443-445)
Use the external attribute for functions never called from the contract.
