Contract ownership is not renounced (belongs to a wallet)

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

TDF._rTotal (contracts/Greeter.sol#30) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
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.

Contract ticker ($TDF) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

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.

TDF.addLiquidity(uint256,uint256) (contracts/Greeter.sol#623-636) ignores return value by _uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (contracts/Greeter.sol#628-635)
