GM [GoldMiner] Token

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

GoldMinerToken._safeTransferETH(address,uint256) (#882-885) sends eth to arbitrary user
Dangerous calls:
- (success) = to.call{gas: 2300,value: value}() (#883)
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.

GoldMinerToken.setSellFeeRate(uint256) (#763-766) should emit an event for:
- sellFeeRate = newSellFeeRate (#765)
Emit an event for critical parameter changes.

solc-0.8.2 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 GoldMinerToken._safeTransferETH(address,uint256) (#882-885):
- (success) = to.call{gas: 2300,value: value}() (#883)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Function IUniswapV2Router01.WETH() (#1049) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#1054) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#1055)
Prevent variables from having similar names.

isExcludedFromRecipientFees(address) should be declared external:
- GoldMinerToken.isExcludedFromRecipientFees(address) (#904-906)
Use the external attribute for functions never called from the contract.
