SymBULL.buyTokens(uint256,address) (#668-679) sends eth to arbitrary user
Dangerous calls:
- router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,to,block.timestamp) (#673-678)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

BountyDistributor.distributeBounty(address) (#353-364) ignores return value by BUSD.transfer(keeper,amount) (#359)
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.

BountyDistributor.process(uint256) (#322-346) has costly operations inside a loop:

SymBULL.isOverLiquified(uint256,uint256) (#772-774) uses timestamp for comparisons
Dangerous comparisons:
- getLiquidityBacking(accuracy) > target (#773)
Avoid relying on block.timestamp.

SymBULL.onlyBuybacker() (#496) compares to a boolean constant:
-require(bool,string)(buyBacker[msg.sender] == true,) (#496)
Remove the equality to the boolean constant.

Additional information: link

SymBULL.swapThreshold (#459) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 2000
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.
