PWE [POWER EVOC] Token

POWEREVOC.addLiquidity(uint256,uint256) (#929-943) sends eth to arbitrary user
Dangerous calls:
- (liquidity) = hashSwapRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#934-941)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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

POWEREVOC._writeCheckpoint(address,uint32,uint256,uint256) (#1202-1220) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1212)
MasterChef.updatePool(uint256) (#1390-1409) uses a dangerous strict equality:
- lpSupply == 0 || pool.allocPoint == 0 (#1399)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

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.
