white paper

Lunar (LNR) is a DeFi ecosystem that aims to solve the biggest problems preventing crypto from true mass adoption. This starts with their Lunar DEX, which initially aims to streamline the entire process of BSC token trading into a single platform with a frictionless user experience.
At the core of the Lunar Ecosystem is the Lunar Token (LNR), which distributes 3% of LNR transactions and a percentage of Lunar DEX transactions to holders in passive earnings. The ecosystem also includes an NFT collection, Lunar Legion, that receives 0.5% of LNR transactions in passive reflections.

Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

Lunar.rescueBEP20Tokens(address) (#908-910) ignores return value by IERC20(tokenAddress).transfer(msg.sender,IERC20(tokenAddress).balanceOf(address(this))) (#909)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Lunar.swapETHForTokens(uint256) (#784-797) sends eth to arbitrary user
Dangerous calls:

Lunar.addLiquidity(uint256,uint256) (#825-838) sends eth to arbitrary user
Dangerous calls:

Ensure that an arbitrary user cannot withdraw unauthorized funds.

Lunar._rTotal (#346) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
Lunar.maxBuyAmount (#348) is set pre-construction with a non-constant function or state variable:
- _tTotal.mul(2).div(100)
Lunar.maxSellAmount (#349) is set pre-construction with a non-constant function or state variable:
- _tTotal.mul(1).div(100)
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.
