CryptoMines Reborn is an NFT game achieved with the effort and attention to detail necessary to provide its users with a long term NFT play-to-earn game, which will allow all players to have a fun and entertaining experience while improving their accounts and collections of hangars, workers, spaceships and fleets, in order to safely traverse our galaxies.
The main goal of Reborn is the search for Dark Matter as a utilitarian material of our Metaverse, this will allow explorers to profit as they progress in their explorations, discoveries, and improve their strategies to obtain profits.
CryptoMines Reborn aims to retake its claimed position as the best NFT play-to-earn game on the BNB Chain, as well as continue the legacy of 'Legacy' and host all the displaced workers to the SIKX19-02 Galaxy.
The game will be released on the BNB Chain and is compatible with web3 wallets such as Metamask, which will be used to pay for transactions and expenses associated with the game. Metamask can be installed as a browser extension, or as an application on mobile devices.
The assets are NFTs owned by the players, they are minted with the ERC-721 standard and can be exchanged with other players in our proprietary Marketplace.

Crux.setRewardsPool(address)._rewardsPool (contracts/Crux.sol#61) lacks a zero-check on :
- rewardsPool = _rewardsPool (contracts/Crux.sol#62)
Check that the address is not zero.

Crux._transfer(address,address,uint256) (contracts/Crux.sol#66-88) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(lastTrade[sender] < (block.timestamp - tradeCooldown),string(No consecutive sells allowed. Please wait.)) (contracts/Crux.sol#75)
Avoid relying on block.timestamp.

Crux._transfer(address,address,uint256) (contracts/Crux.sol#66-88) compares to a boolean constant:
-liquidityPool[sender] == true (contracts/Crux.sol#68)
Crux._transfer(address,address,uint256) (contracts/Crux.sol#66-88) compares to a boolean constant:
-liquidityPool[receiver] == true (contracts/Crux.sol#71)
Remove the equality to the boolean constant.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#4) allows old versions
solc-0.8.10 is not recommended for deployment
Pragma version0.8.10 (contracts/Crux.sol#2) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/utils/Context.sol#4) allows old versions
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.
