DiamondBoyzCoin.addLiquidity(uint256,uint256) (#626-637) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#629-636)
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.

DiamondBoyzCoin._transfer(address,address,uint256).takeFee (#565) 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.

DiamondBoyzCoin.addLiquidity(uint256,uint256) (#626-637) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#629-636)
Ensure that all the return values of the function calls are used.

DiamondBoyzCoin._approve(address,address,uint256).owner (#549) shadows:
- Ownable.owner() (#94-96) (function)
Rename the local variables that shadow another component.

- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#459-461)
Emit an event for critical parameter changes.

SafeMath.mod(uint256,uint256,string) (#77-80) is never used and should be removed
Remove unused functions.

Additional information: link

DiamondBoyzCoin._previousLiquidityFee (#291) 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.

Additional information: link

solc-0.8.4 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 DiamondBoyzCoin._maxTxAmount (#297) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#10)" inContext (#4-13)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable DiamondBoyzCoin._transferFromExcluded(address,address,uint256).rTransferAmount (#683) is too similar to DiamondBoyzCoin._getValues(uint256).tTransferAmount (#473)
Prevent variables from having similar names.

Additional information: link

DiamondBoyzCoin.slitherConstructorVariables() (#266-724) uses literals with too many digits:
- _maxTxAmount = 10000000 * 10 ** 18 (#297)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

DiamondBoyzCoin.numTokensSellToAddToLiquidity (#295) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setRouterAddress(address) should be declared external:
- DiamondBoyzCoin.setRouterAddress(address) (#657-661)
Use the external attribute for functions never called from the contract.
