BlueShib.swapBack() (#339-380) sends eth to arbitrary user
Dangerous calls:
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#364)
- (devSuccess) = address(devFeeReceiver).call{gas: 30000,value: amountBNBdev}() (#366)
BlueShib.manualSend() (#446-449) sends eth to arbitrary user
Dangerous calls:
- address(devFeeReceiver).transfer(contractETHBalance) (#448)
BlueShib.transferForeignToken(address) (#451-455) sends eth to arbitrary user
Dangerous calls:
- address(devFeeReceiver).transfer(_contractBalance) (#454)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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


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.


Contract ownership is not renounced (belongs to a wallet)

BlueShib.slitherConstructorVariables() (#172-471) performs a multiplication on the result of a division:
-swapThreshold = _totalSupply / 10000 * 50 (#212)
Consider ordering multiplication before division.

BlueShib._transferFrom(address,address,uint256) (#274-300) uses timestamp for comparisons
Dangerous comparisons:

Avoid relying on block.timestamp.

BlueShib.buyTokens(uint256,address) (#382-393) is never used and should be removed
Remove unused functions.

Additional information: link

BlueShib._maxTxAmount (#185) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 1) / 100
BlueShib._maxWalletSize (#186) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 2) / 100
BlueShib.swapThreshold (#212) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 10000 * 50
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.

Pragma version^0.8.11 (#11) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 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.

Low level call in BlueShib.swapBack() (#339-380):

- (devSuccess) = address(devFeeReceiver).call{gas: 30000,value: amountBNBdev}() (#366)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Contract ticker ($BSHIB) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Holders:


Average 30d PancakeSwap liquidity is less than $100. Token is either dead or inactive.


Average 30d PancakeSwap volume is less than $100. Token is either dead or inactive.


Number of Binance Smart Chain (BSC) token holders is less than 100. Token is either dead or inactive. Ignore for presale.

Contract has 10% buy tax and 9% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.


Average 30d number of PancakeSwap swaps is low.


Token is deployed only at one blockchain


Token has only one trading pair


Unable to find Telegram and Twitter accounts


Unable to find website, listings and other project-related information


Young tokens have high risks of scam / price dump / death
