Lwazi.swapAndDistributeBNB(uint256) (#1592-1622) sends eth to arbitrary user
Dangerous calls:
- (success,None) = address(productWallet).call{value: forProduct}() (#1609)
- (success,None) = address(dividendTracker).call{value: forDividends}() (#1616)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Lwazi.withdrawStuckTokens(address,uint256) (#1624-1626) ignores return value by IERC20(_token).transfer(msg.sender,_amount) (#1625)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.


Combination 2: Unchecked transfer + 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.


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.

Contract name (Lwazi.io) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Lwazi._transfer(address,address,uint256).lastProcessedIndex (#1563) 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.

Additional information: link

Lwazi._transfer(address,address,uint256) (#1496-1570) ignores return value by dividendTracker.process(gas) (#1563-1568)
Ensure that all the return values of the function calls are used.

DividendPayingToken.constructor(string,string)._symbol (#815) shadows:
- ERC20._symbol (#132) (state variable)
Rename the local variables that shadow another component.

Additional information: link

Lwazi.updatePancakeRouter(address)._pancakePair (#1318-1319) lacks a zero-check on :
- pancakePair = _pancakePair (#1320)
Check that the address is not zero.

Variable 'Lwazi._transfer(address,address,uint256).lastProcessedIndex (#1563)' in Lwazi._transfer(address,address,uint256) (#1496-1570) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1564)
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.

LwaziDividendTracker.canAutoClaim(uint256) (#1753-1759) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1754)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1758)
Avoid relying on block.timestamp.

SafeMathInt.mul(int256,int256) (#457-465) is never used and should be removed
Remove unused functions.

Additional information: link

Lwazi.swapTokensAtAmount (#1227) is set pre-construction with a non-constant function or state variable:
- 50 * (10 ** decimals())
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-0.8.0 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.

Low level call in Lwazi.swapAndDistributeBNB(uint256) (#1592-1622):
- (success) = address(marketingWallet).call{value: forMarketing}() (#1602)
- (success,None) = address(productWallet).call{value: forProduct}() (#1609)
- (success,None) = address(dividendTracker).call{value: forDividends}() (#1616)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Parameter LwaziDividendTracker.getAccount(address)._account (#1691) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable DividendPayingToken._withdrawDividendOfUser(address)._withdrawableDividend (#861) is too similar to LwaziDividendTracker.getAccount(address).withdrawableDividends (#1695)
Prevent variables from having similar names.

Additional information: link

LwaziDividendTracker.getAccountAtIndex(uint256) (#1734-1751) uses literals with too many digits:
- (0x0000000000000000000000000000000000000000,- 1,- 1,0,0,0,0,0) (#1745)
Use: Ether suffix, Time suffix, or The scientific notation

Ownable._previousOwner (#962) is never used in LwaziDividendTracker (#1629-1839)
Remove unused state variables.

Additional information: link

Ownable._previousOwner (#962) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

process(uint256) should be declared external:
- LwaziDividendTracker.process(uint256) (#1780-1825)
Use the external attribute for functions never called from the contract.
