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

SafeMath is re-used:
- contracts/utils/SafeMath.sol#5-57
- @openzeppelin/contracts/math/SafeMath.sol#18-214
Rename the contract.

MetaSoldierToken.transferMarker(address).newMaker (contracts/token_msd/MetaSoldierToken.sol#84) lacks a zero-check on :
- maker = newMaker (contracts/token_msd/MetaSoldierToken.sol#86)
Check that the address is not zero.

Use one Solidity version.

TransferHelper.safeTransferETH(address,uint256) (contracts/pancake/TransferHelper.sol#47-50) is never used and should be removed
Remove unused functions.

Additional information: link

MetaSoldierToken.pancakeRouter (contracts/token_msd/MetaSoldierToken.sol#38) is set pre-construction with a non-constant function or state variable:
- IPancakeRouter01(PANCAKE_ROUTER_ADDRESS)
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-0.7.0 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

Low level call in TransferHelper.safeTransferETH(address,uint256) (contracts/pancake/TransferHelper.sol#47-50):
- (success) = to.call{value: value}(new bytes(0)) (contracts/pancake/TransferHelper.sol#48)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable MetaSoldierToken.USDTAddress (contracts/token_msd/MetaSoldierToken.sol#40) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (@openzeppelin/contracts/utils/Context.sol#21)" inContext (@openzeppelin/contracts/utils/Context.sol#15-24)
Remove redundant statements if they congest code but offer no value.

Variable MetaSoldierToken.addLiquidity(uint256,uint256,uint256,uint256,address,uint256).amountADesired (contracts/token_msd/MetaSoldierToken.sol#191) is too similar to MetaSoldierToken.addLiquidity(uint256,uint256,uint256,uint256,address,uint256).amountBDesired (contracts/token_msd/MetaSoldierToken.sol#192)
Prevent variables from having similar names.

Additional information: link

MetaSoldierToken.constructor(address) (contracts/token_msd/MetaSoldierToken.sol#55-64) uses literals with too many digits:
- TemplateERC20Token(Meta Soldier Token,MSD,10000000000e18,premintReceiptor) (contracts/token_msd/MetaSoldierToken.sol#56-61)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

MetaSoldierToken.USDTAddress (contracts/token_msd/MetaSoldierToken.sol#40) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

addLiquidity(uint256,uint256,uint256,uint256,address,uint256) should be declared external:
- MetaSoldierToken.addLiquidity(uint256,uint256,uint256,uint256,address,uint256) (contracts/token_msd/MetaSoldierToken.sol#189-210)
Use the external attribute for functions never called from the contract.
