Reentrancy in DividendPayingToken._withdrawDividendOfUser(address) (contracts/interfaces/DividendPayingToken.sol#87-103):
External calls:
- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (contracts/interfaces/DividendPayingToken.sol#92)
State variables written after the call(s):
- withdrawnDividends[user] = withdrawnDividends[user].sub(_withdrawableDividend) (contracts/interfaces/DividendPayingToken.sol#95)

MiniNBA._transfer(address,address,uint256).iterations (contracts/MiniNBA.sol#339) 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.

MiniNBA.addLiquidity(uint256,uint256) (contracts/MiniNBA.sol#392-407) ignores return value by pancakeswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (contracts/MiniNBA.sol#398-405)
Ensure that all the return values of the function calls are used.

DividendPayingToken.constructor(string,string,uint8)._decimals (contracts/interfaces/DividendPayingToken.sol#44) shadows:
- BEP20._decimals (contracts/interfaces/BEP20.sol#43) (state variable)
Rename the local variables that shadow another component.

MiniNBA.setSwapAt(uint256) (contracts/MiniNBA.sol#199-201) should emit an event for:
- swapTokensAtAmount = swapAmount (contracts/MiniNBA.sol#200)

Variable 'MiniNBA._transfer(address,address,uint256).claims (contracts/MiniNBA.sol#339)' in MiniNBA._transfer(address,address,uint256) (contracts/MiniNBA.sol#255-346) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (contracts/MiniNBA.sol#340)
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.

MiniNBADividendTracker.canAutoClaim(uint256) (contracts/MiniNBADividendTracker.sol#133-139) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (contracts/MiniNBADividendTracker.sol#134)
- block.timestamp.sub(lastClaimTime) >= claimWait (contracts/MiniNBADividendTracker.sol#138)
Avoid relying on block.timestamp.

solc-0.8.0 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.

- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (contracts/interfaces/DividendPayingToken.sol#92)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
