WBT [World Bet] Token

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

WorldBetToken.swapBack() (#734-775) sends eth to arbitrary user
Dangerous calls:
- (success) = address(treasuryReceiver).call{gas: 30000,value: amountETHToTreasuryAndReward.mul(treasuryFee).div(_currentFee)}() (#762-765)
- (success,None) = address(rewardReceiver).call{gas: 30000,value: amountETHToTreasuryAndReward.mul(rewardFee).div(_currentFee)}() (#767-772)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

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.

WorldBetToken.swapBack().success (#762) is written in both
(success) = address(treasuryReceiver).call{gas: 30000,value: amountETHToTreasuryAndReward.mul(treasuryFee).div(_currentFee)}() (#762-765)
(success,None) = address(rewardReceiver).call{gas: 30000,value: amountETHToTreasuryAndReward.mul(rewardFee).div(_currentFee)}() (#767-772)
Fix or remove the writes.

WorldBetToken.addLiquidity() (#777-818) ignores return value by router.addLiquidityETH{value: amountETHLiquidity}(address(this),amountToLiquify,0,0,treasuryReceiver,block.timestamp) (#808-815)
Ensure that all the return values of the function calls are used.

Additional information: link

WorldBetToken.totalFee (#572) is set pre-construction with a non-constant function or state variable:
- treasuryFee.add(rewardFee).add(liquidityFee).add(burnFee)
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.

WorldBetToken.getLiquidityBacking(uint256) (#969-977) performs a multiplication on the result of a division:
-liquidityBalance = _gonBalances[pair].div(_gonsPerFragment) (#974)
-accuracy.mul(liquidityBalance.mul(2)).div(getCirculatingSupply()) (#975-976)
Consider ordering multiplication before division.
