MousePad.addLiquidity(uint256,uint256) (#935-948) sends eth to arbitrary user
Dangerous calls:
- _uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#940-947)
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.
MousePad.addLiquidity(uint256,uint256) (#935-948) ignores return value by _uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#940-947)
Ensure that all the return values of the function calls are used.

MousePad._approve(address,address,uint256).owner (#834) shadows:
- Ownable.owner() (#317-319) (function)
Rename the local variables that shadow another component.

MousePad.setMaxTxPercent(uint256) (#753-755) should emit an event for:
- _maxTxAmount = _tTotal.mul(maxTxPercent).div(100) (#754)
Emit an event for critical parameter changes.

MousePad.setUniswapPair(address).p (#769) lacks a zero-check on :
- _uniswapV2Pair = p (#770)
Check that the address is not zero.

SafeMathUint.toInt256Safe(uint256) (#300-304) is never used and should be removed
Remove unused functions.
Additional information: link
MousePad._rTotal (#559) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
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-0.8.7 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.

Variable MousePad._getRValues(uint256,uint256,uint256,uint256).rTransferAmount (#794) is too similar to MousePad._transferFromExcluded(address,address,uint256).tTransferAmount (#1024)
Prevent variables from having similar names.
Additional information: link
MousePad.slitherConstructorVariables() (#544-1038) uses literals with too many digits:
- _minTokenBalance = 100000 * 10 ** 18 (#571)
Use: Ether suffix, Time suffix, or The scientific notation

Ownable._previousOwner (#308) is never used in MousePad (#544-1038)
Remove unused state variables.
Additional information: link
Ownable._previousOwner (#308) should be constant
Add the constant attributes to state variables that never change.

isExcludedFromFee(address) should be declared external:
- MousePad.isExcludedFromFee(address) (#830-832)
Use the external attribute for functions never called from the contract.
