SHIH [Shih Tzu] Token

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

Contract ownership is not renounced (belongs to a wallet)

Redundant expression "this (#152)" inContext (#146-155)
Remove redundant statements if they congest code but offer no value.

ERC20._transfer(address,address,uint256) (#379-441) ignores return value by uniswap.swapExactTokensForETH((bal),1,path,address(this),deadline) (#405)
ERC20.addliquidity(uint256) (#449-456) ignores return value by uniswap.addLiquidityETH{value: values}(address(this),amount,0,0,devWalletAddress,deadline) (#455)
Ensure that all the return values of the function calls are used.

Contract has 4% buy tax and 4% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Average 30d number of PancakeSwap swaps is low.

BscScan page for the token does not contain additional info: website, socials, description, etc.
