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

BoorioToken.addLiquidity(uint256,uint256) (#912-923) ignores return value by _uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp + 3600) (#914-921)
Ensure that all the return values of the function calls are used.

BoorioToken._approve(address,address,uint256).owner (#974) shadows:
- Ownable.owner() (#63-65) (function)
Rename the local variables that shadow another component.

Pragma version>=0.4.0 (#581) allows old versions
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.
