EverGrow.buyTokens(uint256,address) (#637-648) sends eth to arbitrary user
Dangerous calls:
- router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,to,block.timestamp) (#642-647)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

EverGrow.triggerDistributor(uint256) (#740-747) ignores return value by token.transfer(msg.sender,amount) (#745)
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.

claim() should be declared external:
- EverGrow.claim() (#685-687)
Use the external attribute for functions never called from the contract.

EverGrow.isOverLiquified(uint256,uint256) (#762-764) uses timestamp for comparisons
Dangerous comparisons:

EverGrow.onlyBuybacker() (#473) compares to a boolean constant:
-require(bool,string)(buyBacker[msg.sender] == true,) (#473)
Remove the equality to the boolean constant.

EverGrow.launched() (#666-668) is never used and should be removed
Remove unused functions.

Additional information: link

EverGrow.swapThreshold (#436) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 20000
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 EverGrow.swapBack() (#568-608):
- address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#595)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
