⚡️META MOON NFT ⚡️

With WEB 3.0, people were already able to communicate with each other online via digital platforms. However, Metaverse will take the dimension of human interactions to a very different dimension than that. With Metaverse, people will be able to find themselves in a digital universe through augmented reality and get lost in this universe.

METAMOONNFT.addLiquidity(uint256,uint256) (#749-762) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#754-761)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)


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.

METAMOONNFT._totalSupply (#422) is set pre-construction with a non-constant function or state variable:

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.
