BABYTOKEN.addLiquidity(uint256,uint256) (#3017-3030) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#3022-3029)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

BABYTOKEN.swapAndSendToFee(uint256) (#2946-2956) ignores return value by IERC20(rewardToken).transfer(_marketingWalletAddress,newBalance) (#2955)

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


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.


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.

BABYTOKENDividendTracker.getAccount(address) (#3130-3177) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (#3174-3176)
BABYTOKENDividendTracker.canAutoClaim(uint256) (#3202-3208) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#3203)
