MartianDoge.addLiquidity(uint256,uint256) (#855-868) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,LP_Reciever,block.timestamp) (#860-867)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

MartianDoge.checkBuyBack() (#767-803) uses a weak PRNG: "_bBSLimit = _bBSLimitMin + uint256(keccak256(bytes)(abi.encodePacked(block.timestamp,block.difficulty))) % (_bBSLimitMax - _bBSLimitMin + 1) (#797)"
Do not use block.timestamp, now or blockhash as a source of randomness

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


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.

MartianDoge._transfer(address,address,uint256).sellHistory (#691) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Additional information: link

MartianDoge.addLiquidity(uint256,uint256) (#855-868) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,LP_Reciever,block.timestamp) (#860-867)
Ensure that all the return values of the function calls are used.

MartianDoge._approve(address,address,uint256).owner (#664) shadows:
- Ownable.owner() (#166-168) (function)
Rename the local variables that shadow another component.

MartianDoge.setNumTokensSellToAddToBuyBack(uint256) (#1117-1119) should emit an event for:
- minimumTokensBeforeSwap = _minimumTokensBeforeSwap (#1118)
Emit an event for critical parameter changes.

MartianDoge.setMarketingAddress(address)._marketingAddress (#1121) lacks a zero-check on :
- marketingAddress = address(_marketingAddress) (#1122)
Check that the address is not zero.

MartianDoge._removeOldSellHistories() (#1034-1056) uses timestamp for comparisons
Dangerous comparisons:
- j < _sellHistories.length (#1038)
- _sellHistories[j].time >= maxStartTimeForHistories (#1040)
- j_scope_0 < removedCnt (#1051)
Avoid relying on block.timestamp.

Do not use evm assembly.

SafeMath.mod(uint256,uint256,string) (#67-70) is never used and should be removed
Remove unused functions.

Additional information: link

MartianDoge._previousLiquidityFee (#466) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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-0.8.7 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 Address._functionCallWithValue(address,bytes,uint256,string) (#133-150):
- (success,returndata) = target.call{value: weiValue}(data) (#136)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable MartianDoge._isEnabledBuyBackAndBurn (#501) is not in mixedCase
Follow the Solidity naming convention.

Variable MartianDoge._transferStandard(address,address,uint256).rTransferAmount (#889) is too similar to MartianDoge._transferFromExcluded(address,address,uint256).tTransferAmount (#908)
Prevent variables from having similar names.

MartianDoge.slitherConstructorVariables() (#419-1202) uses literals with too many digits:
- buyBackSellLimit = 1000000000 * 10 ** 18 (#488)
Use: Ether suffix, Time suffix, or The scientific notation

MartianDoge.deadAddress (#424) should be constant
Add the constant attributes to state variables that never change.

transferForeignToken(address,address) should be declared external:
- MartianDoge.transferForeignToken(address,address) (#1177-1181)
Use the external attribute for functions never called from the contract.
