RTM [RETRIUM NETWORK] Token

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

RetriumNetwork.swapBack() (#335-376) sends eth to arbitrary user
Dangerous calls:
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#360)
- (devSuccess) = address(devFeeReceiver).call{gas: 30000,value: amountBNBdev}() (#362)
RetriumNetwork.manualSend() (#442-445) sends eth to arbitrary user
Dangerous calls:
- address(devFeeReceiver).transfer(contractETHBalance) (#444)
RetriumNetwork.transferForeignToken(address) (#447-451) sends eth to arbitrary user
Dangerous calls:
- address(devFeeReceiver).transfer(_contractBalance) (#450)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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)

RetriumNetwork.slitherConstructorVariables() (#168-467) performs a multiplication on the result of a division:
-swapThreshold = _totalSupply / 10000 * 50 (#208)
Consider ordering multiplication before division.

Remove unused functions.

RetriumNetwork._maxTxAmount (#181) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 2) / 100
RetriumNetwork._maxWalletSize (#182) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 2) / 100
RetriumNetwork.swapThreshold (#208) 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 (#7) 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 RetriumNetwork.swapBack() (#335-376):

- (devSuccess) = address(devFeeReceiver).call{gas: 30000,value: amountBNBdev}() (#362)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
