TRUST [Trust Inu] Token

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

TRUST.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)
TRUST.manualSend() (#446-449) sends eth to arbitrary user
Dangerous calls:
- address(devFeeReceiver).transfer(contractETHBalance) (#448)
TRUST.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.

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.

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.

TRUST._transferFrom(address,address,uint256) (#274-300) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(cooldownTimer[recipient] < block.timestamp,Please wait for 1min between two operations) (#286)
Avoid relying on block.timestamp.

Low level call in TRUST.swapBack() (#339-380):
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#364)
- (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

TRUST._maxTxAmount (#185) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 100) / 100
TRUST._maxWalletSize (#186) is set pre-construction with a non-constant function or state variable:
