ShibUp._transfer(address,address,uint256).lastProcessedIndex (contracts/ShibUp.sol#1850) 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.

ShibUp.addLiquidity(uint256,uint256) (contracts/ShibUp.sol#1955-1968) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,_liquidityWallet,block.timestamp) (contracts/ShibUp.sol#1960-1967)
Ensure that all the return values of the function calls are used.

DividendPayingToken.accumulativeDividendOf(address)._owner (contracts/ShibUp.sol#1383) shadows:

ShibUpDividendTracker.setLastProcessedIndex(uint256) (contracts/ShibUp.sol#2056-2058) should emit an event for:
- lastProcessedIndex = index (contracts/ShibUp.sol#2057)
Emit an event for critical parameter changes.

ShibUp.setLiquidityWallet(address).wallet (contracts/ShibUp.sol#1588) lacks a zero-check on :
- _liquidityWallet = wallet (contracts/ShibUp.sol#1589)

Variable 'ShibUp._transfer(address,address,uint256).claims (contracts/ShibUp.sol#1849)' in ShibUp._transfer(address,address,uint256) (contracts/ShibUp.sol#1760-1862) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (contracts/ShibUp.sol#1852-1859)
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.

ShibUpDividendTracker.canAutoClaim(uint256) (contracts/ShibUp.sol#2149-2155) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (contracts/ShibUp.sol#2150)
- block.timestamp.sub(lastClaimTime) >= claimWait (contracts/ShibUp.sol#2154)
Avoid relying on block.timestamp.

SafeMathInt.mul(int256,int256) (contracts/ShibUp.sol#446-453) is never used and should be removed
Remove unused functions.

Additional information: link

ShibUp.totalFees (contracts/ShibUp.sol#1481-1484) is set pre-construction with a non-constant function or state variable:
- SHIBRewardsFee.add(liquidityFee).add(buyBackAndBurnFee).add(marketingFee)
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.

- (success) = address(_marketingWallet).call{value: marketingBnb}() (contracts/ShibUp.sol#1806-1808)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
