SPAM [SPACEMERGER] Token

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

SpacesToken.addLiquidity(uint256,uint256) (#2116-2126) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#2118-2125)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

SpacesToken.swapAndSendToFee(uint256) (#2056-2066) ignores return value by IERC20(rewardToken).transfer(_marketingWalletAddress,newBalance) (#2065)

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

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.

Combination 2: Unchecked transfer + 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.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
