Laser Scorebeta Last Audit: 2 March 2022

report
Token is either risky or in presale. For presale 30+ is a fine score.


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

SmartFinance.addLiquidity(uint256,uint256) (#3125-3138) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#3130-3137)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.
