Token seems to be a scam (type: unclassified scam).


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

Reentrancy in Bremen._transfer(address,address,uint256) (#285-343):
External calls:
- swapTokensForEth(contractTokenBalance) (#313)
- uniswapV2Router.swapExactTokensForETHSupportingFeeOnTransferTokens(tokenAmount,0,path,address(this),block.timestamp) (#350-356)
External calls sending eth:
- sendETHToFee(address(this).balance) (#316)
- _marketingAddress.transfer(amount) (#360)
State variables written after the call(s):
- _tokenTransfer(from,to,amount,takeFee) (#342)
- _rOwned[address(this)] = _rOwned[address(this)].add(rTeam) (#397)
- _rOwned[sender] = _rOwned[sender].sub(rAmount) (#387)
- _rOwned[recipient] = _rOwned[recipient].add(rTransferAmount) (#388)
- _tokenTransfer(from,to,amount,takeFee) (#342)
- _rTotal = _rTotal.sub(rFee) (#401)
Apply the check-effects-interactions pattern.

Additional information: link

Bremen._previoustaxFee (#164) is set pre-construction with a non-constant function or state variable:
- _taxFee
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.

Additional information: link

solc-0.8.9 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.

Additional information: link

Variable Bremen._swapTokensAtAmount (#180) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Bremen._approve(address,address,uint256).owner (#278) shadows:
- Ownable.owner() (#58-60) (function)
Rename the local variables that shadow another component.

Additional information: link

Bremen.setMaxWalletSize(uint256) (#471-473) should emit an event for:
- _maxWalletSize = maxWalletSize (#472)
Emit an event for critical parameter changes.

- _approve(sender,_msgSender(),_allowances[sender][_msgSender()].sub(amount,ERC20: transfer amount exceeds allowance)) (#243-250)
- _allowances[owner][spender] = amount (#281)
Apply the check-effects-interactions pattern.

Variable Bremen._getRValues(uint256,uint256,uint256,uint256).rTransferAmount (#429) is too similar to Bremen._getTValues(uint256,uint256,uint256).tTransferAmount (#420)
Prevent variables from having similar names.

Additional information: link

Bremen.slitherConstructorConstantVariables() (#134-480) uses literals with too many digits:
- _tTotal = 10000000000000 * 10 ** 9 (#147)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

Bremen.cooldown (#167) is never used in Bremen (#134-480)
Remove unused state variables.

Additional information: link

Ownable._previousOwner (#46) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

allowPreTrading(address,bool) should be declared external:
- Bremen.allowPreTrading(address,bool) (#475-478)
Use the external attribute for functions never called from the contract.
