Token seems to be a scam (type: honeypot scam).

LZ20.addLiquidity(uint256,uint256) (#820-833) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#825-832)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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


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.


Contract ownership is not renounced (belongs to a wallet)

LZ20.addLiquidity(uint256,uint256) (#820-833) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#825-832)
Ensure that all the return values of the function calls are used.
