BURGER [BeefSwap] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract ownership is not renounced (belongs to a wallet)

BeefSwap.constructor(address,address)._treasuryAddress (#120) lacks a zero-check on :
- treasuryAddress = _treasuryAddress (#122)
BeefSwap.constructor(address,address).admin (#120) lacks a zero-check on :
- ADMINISTRATOR = admin (#123)
BeefSwap.withdraw()._customerAddress (#204) lacks a zero-check on :
- _customerAddress.transfer(_dividends) (#214)
Check that the address is not zero.

Pragma version^0.4.25 (#1) allows old versions
solc-0.4.25 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.

BeefSwap.sell(uint256) (#223-260) performs a multiplication on the result of a division:
-_dividends = SafeMath.div(SafeMath.mul(_ethereum,sellFee_),100) (#233)
-profitPerShare_ = SafeMath.add(profitPerShare_,(_dividends * magnitude) / tokenSupply_) (#254)
BeefSwap.purchaseTokens(uint256,address) (#485-531) performs a multiplication on the result of a division:
-_fee = _fee - (_fee - (_amountOfTokens * (_dividends * magnitude / (tokenSupply_)))) (#516)
BeefSwap.tokensToEthereum_(uint256) (#633-655) performs a multiplication on the result of a division:
-_etherReceived = (SafeMath.sub((((tokenPriceInitial_ + (tokenPriceIncremental_ * (_tokenSupply / 1e18))) - tokenPriceIncremental_) * (tokens_ - 1e18)),(tokenPriceIncremental_ * ((tokens_ ** 2 - tokens_) / 1e18)) / 2) / 1e18) (#641-653)
Consider ordering multiplication before division.

BeefSwap.fallback() (#147-153) should emit an event for:
- totalTradingVolume = SafeMath.add(totalTradingVolume,msg.value) (#151)
