white paper

Crypto Jackpot aims to build multiple revenue streams that will boost the Jackpot pools and project utility thus organically growing the value of the token. Initially, Crypto Jackpot will hold Jackpot draws weekly. As the volume increases so will the Jackpots. Our aim is to become the biggest cryptocurrency giveaway token on the BSC network, with our tokenomics supplying the Jackpot pools with every transaction.

CryptoJackpot.swapAndLiquify(uint256) (#1418-1446) sends eth to arbitrary user
Dangerous calls:
- marketingWallet.transfer(address(this).balance) (#1443)
CryptoJackpot.addLiquidity(uint256,uint256) (#1471-1483) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1474-1481)
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.

CryptoJackpot.addLiquidity(uint256,uint256) (#1471-1483) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1474-1481)

Pragma version0.8.9 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
