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

Jackpot_LiquidityTokenBaseMixin._transferBasic(address,address,uint256) (#418-424) contains a tautology or contradiction:
- require(bool,string)(balances[sender] - amount >= 0,Can't go lower than 0) (#419)
Fix the incorrect comparison by changing the value type or the comparison.

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.

Pragma version=0.8.11 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 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.
