UMG [UnderMineGold] Token

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

Contract creator or owner is blacklisted for past scams

Contract locking ether found:
Contract UnderMineGold (UnderMineGold.sol#14-235) has payable functions:
- UnderMineGold.receive() (UnderMineGold.sol#234)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

UnderMineGold.antiBot(uint256) (UnderMineGold.sol#132-139) should emit an event for:
- antiBotAmount = amount (UnderMineGold.sol#136)
Emit an event for critical parameter changes.

UnderMineGold._transfer(address,address,uint256) (UnderMineGold.sol#201-231) performs a multiplication on the result of a division:
-_fee = amount.mul(transferFeeRate).div(100) (UnderMineGold.sol#224)
-super._transfer(address(this),addressForMarketing,_fee.mul(marketingDivisor).div(100)) (UnderMineGold.sol#226)
Consider ordering multiplication before division.

Reentrancy in UnderMineGold.swapTokensForEth(uint256) (UnderMineGold.sol#148-166):
External calls:
- uniswapV2Router.swapExactTokensForETHSupportingFeeOnTransferTokens(tokenAmount,0,path,addressForMarketing,block.timestamp) (UnderMineGold.sol#157-163)
State variables written after the call(s):
- tokensForMarketing = tokensForMarketing.sub(tokenAmount) (UnderMineGold.sol#165)
Apply the check-effects-interactions pattern.

Reentrancy in UnderMineGold.constructor() (UnderMineGold.sol#51-64):
External calls:
- uniswapV2Pair = _uniswapV2Factory.createPair(address(this),_uniswapV2Router.WETH()) (UnderMineGold.sol#60)
Event emitted after the call(s):
- Approval(owner,spender,amount) (ERC20.sol#312)
- _approve(address(this),address(uniswapV2Router),~ uint256(0)) (UnderMineGold.sol#63)
Apply the check-effects-interactions pattern.

UnderMineGold._transfer(address,address,uint256) (UnderMineGold.sol#201-231) uses timestamp for comparisons
Dangerous comparisons:
- botAddresses[sender] && amount > antiBotAmount && antiBotTime > block.timestamp (UnderMineGold.sol#207-209)
Avoid relying on block.timestamp.

Different versions of Solidity is used:
- Version used: ['>=0.5.0', '>=0.6.2', '^0.8.0', '^0.8.2']
- ^0.8.0 (Context.sol#3)
- ^0.8.0 (ERC20.sol#3)
- ^0.8.0 (ERC20Burnable.sol#3)
- ^0.8.0 (IERC20.sol#3)
- ^0.8.0 (IERC20Metadata.sol#3)
- >=0.5.0 (IUniswapV2Factory.sol#3)
- >=0.6.2 (IUniswapV2Router01.sol#3)
- >=0.6.2 (IUniswapV2Router02.sol#3)
- ^0.8.2 (ManagerInterface.sol#3)
- ^0.8.0 (Ownable.sol#3)
- ^0.8.0 (SafeMath.sol#3)
- ^0.8.2 (UnderMineGold.sol#3)
Use one Solidity version.

SafeMath.trySub(uint256,uint256) (SafeMath.sol#34-39) is never used and should be removed
Remove unused functions.

Additional information: link

UnderMineGold.tokensForAirdrop (UnderMineGold.sol#34) is set pre-construction with a non-constant function or state variable:
- MAX_TOKENS_FOR_AIRDROP
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-0.8.4 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 UnderMineGold.MAX_TOKENS_FOR_AIRDROP (UnderMineGold.sol#20) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (IUniswapV2Router01.sol#12) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (IUniswapV2Router01.sol#13)
Prevent variables from having similar names.

Additional information: link

UnderMineGold.slitherConstructorVariables() (UnderMineGold.sol#14-235) uses literals with too many digits:
- MAX_TOKENS_FOR_AIRDROP = 20000000 * 10 ** 9 (UnderMineGold.sol#20)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

UnderMineGold.sellFeeRate (UnderMineGold.sol#43) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

includeInFee(address) should be declared external:
- UnderMineGold.includeInFee(address) (UnderMineGold.sol#188-190)
Use the external attribute for functions never called from the contract.
