TMR [TheMatrixRev] Token

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

Contract locking ether found:
Contract TheMatrixRev (#867-1047) has payable functions:
- TheMatrixRev.receive() (#1045)
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.

TheMatrixRev.BurnAddr (#876) should be constant
TheMatrixRev.MAX_LOCK (#872) should be constant
TheMatrixRev.MAX_TOKENS_FOR_REWARDS (#871) should be constant
TheMatrixRev.MAX_TOTAL_SUPPLY (#870) should be constant
TheMatrixRev.antiBotDuration (#892) should be constant
TheMatrixRev.buyFeeRate (#898) should be constant
TheMatrixRev.sellFeeRate (#897) should be constant
Add the constant attributes to state variables that never change.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#735) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#736)
Prevent variables from having similar names.

TheMatrixRev._transfer(address,address,uint256) (#987-1042) performs a multiplication on the result of a division:
-_fee_scope_0 = amount.mul(buyFeeRate).div(100) (#1034)
-super._transfer(sender,addressForMarketing,_fee_scope_0.sub(_fee_scope_0.mul(60).div(100))) (#1036)
Consider ordering multiplication before division.

TheMatrixRev.antiBot(uint256) (#947-954) should emit an event for:
- antiBotAmount = amount (#951)
Emit an event for critical parameter changes.

TheMatrixRev.SetMintContract(address).contrat_addr (#972) lacks a zero-check on :
- mintContract = contrat_addr (#974)
Check that the address is not zero.

Additional information: link

TheMatrixRev._transfer(address,address,uint256) (#987-1042) uses timestamp for comparisons
Dangerous comparisons:
- botAddresses[sender] && amount > antiBotAmount && antiBotTime > block.timestamp (#993-995)
- unlockTime > block.timestamp (#1002)
Avoid relying on block.timestamp.

TheMatrixRev.tokensForRewards (#888) is set pre-construction with a non-constant function or state variable:
- MAX_TOKENS_FOR_REWARDS
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.

Pragma version^0.8.2 (#2) allows old versions
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.
