FANTA.swapAndLiquify(uint256) (#947-977) sends eth to arbitrary user
Dangerous calls:
- wallet.transfer(oneThird) (#967)
- rewardsWallet.transfer(oneThird) (#968)
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.


Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

FANTA.addLiquidity(uint256,uint256) (#999-1012) ignores return value by pancakeRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1004-1011)
Ensure that all the return values of the function calls are used.

FANTA._approve(address,address,uint256).owner (#869) shadows:
- Ownable.owner() (#418-420) (function)
Rename the local variables that shadow another component.

- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#1177-1179)
Emit an event for critical parameter changes.

Ownable.unlock() (#465-470) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#467)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#363-384) uses assembly
- INLINE ASM (#376-379)
Do not use evm assembly.

Additional information: link

FANTA._transfer(address,address,uint256) (#897-945) compares to a boolean constant:
-limit == true && from != owner() && to != owner() (#905)
Remove the equality to the boolean constant.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#243-246) is never used and should be removed
Remove unused functions.

Additional information: link

FANTA._maxTxAmount (#718) is set pre-construction with a non-constant function or state variable:
- _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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#363-384):
- (success,returndata) = target.call{value: weiValue}(data) (#367)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable FANTA._maxTxAmount (#718) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#10)" inContext (#4-13)

Variable FANTA._transferBothExcluded(address,address,uint256).rTransferAmount (#1065) is too similar to FANTA._getValues(uint256).tTransferAmount (#1081)
Prevent variables from having similar names.

Additional information: link

FANTA.slitherConstructorVariables() (#686-1190) uses literals with too many digits:
- _tTotal = 100000000 * 10 ** 18 (#699)
Use: Ether suffix, Time suffix, or The scientific notation

FANTA.minTokensBeforeSwap (#726) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setSwapAndLiquifyEnabled(bool) should be declared external:
- FANTA.setSwapAndLiquifyEnabled(bool) (#1182-1185)
Use the external attribute for functions never called from the contract.
