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

Contract locking ether found:
Contract ZED (#400-511) has payable functions:
- ZED.receive() (#479)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Additional information: link

ZED._maxTxAmountBUY (#415) should be constant
ZED._maxTxAmountSELL (#416) should be constant
Add the constant attributes to state variables that never change.

Function IUniswapV2Pair.DOMAIN_SEPARATOR() (#223) is not in mixedCase
Function IUniswapV2Pair.PERMIT_TYPEHASH() (#224) is not in mixedCase
Function IUniswapV2Pair.MINIMUM_LIQUIDITY() (#241) is not in mixedCase
Function IUniswapV2Router01.WETH() (#261) is not in mixedCase
Variable ZED._balances (#408) is not in mixedCase
Variable ZED._allowances (#409) is not in mixedCase
Variable ZED._totalSupply (#412) is not in mixedCase
Variable ZED._maxTxAmountBUY (#415) is not in mixedCase
Variable ZED._maxTxAmountSELL (#416) is not in mixedCase
Follow the Solidity naming convention.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#266) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#267)
Prevent variables from having similar names.

Apply the check-effects-interactions pattern.

Pragma version^0.8.11 (#11) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 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 SafeBEP20.callOptionalReturn(IBEP20,bytes) (#177-188):
- (success,returndata) = address(token).call(data) (#181)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
