WORM [WormFi] Token

Worm.transferTokens(uint256) (#582-604) sends eth to arbitrary user
Dangerous calls:
- _prizeWallet.transfer(prizeBNB) (#600)
- _marketingWallet.transfer(marketingBNB) (#603)
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.

Worm.addLiqudity(uint256,uint256) (#628-641) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#633-640)

Worm._transfer(address,address,uint256) (#510-553) uses timestamp for comparisons
Dangerous comparisons:
- block.timestamp < _startTime[from] + (86400) (#529)
