HeroesOfCrypton.swapBack(uint256) (#651-696) sends eth to arbitrary user
Dangerous calls:
- marketingFeeReceiver.transfer(amountBNBMarketing) (#680)
- founderReceiver1.transfer(amountBNBFounder / 2) (#682)
- founderReceiver2.transfer(amountBNBFounder / 2) (#683)
- router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,liquidityFeeReceiver,block.timestamp) (#687-694)
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.

Contract ownership is not renounced (belongs to a wallet)

HeroesOfCrypton._transferFrom(address,address,uint256) (#546-577) uses timestamp for comparisons
Dangerous comparisons:
- ! launched() && liquidityPools[recipient] (#551)
HeroesOfCrypton.launched() (#579-581) uses timestamp for comparisons
Dangerous comparisons:
- launchedTime != 0 (#580)
Avoid relying on block.timestamp.

Pragma version^0.8.9 (#6) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 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.
