white paper

In the future, through years of endeavor over generations, humanity will finally turn the magnificent dream of Dyson Ball into reality and the energy crisis will be solved.

Human beings simulate real space and time with the supercomputer “droplets” as the core, and synchronize the laws of the universe and human consciousness to the virtual world. The virtual world is like the universe evolving from a singularity, and finally upgraded to a virtual universe that connects all life consciousness. Humans named the virtual universe “Metaverse”.

The operation of “Metaverse” requires powerful computing power and energy, and the computing power of “droplets” has gradually reached its limit, which requires the construction of more energy supplies. To this end, the “Metaverse” Management Alliance started a project code-named “Metaverse Miner”. It aims to encourage adventurous explorers to explore a wider range of galaxies, use terminal control machines to obtain various primal energies in unfamiliar galaxies, and link “Metaverse” to every human planet through the interstellar logistics network.

MetaToken._rTotal (contracts/MetaToken.sol#873) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
MetaToken._previousTaxFee (contracts/MetaToken.sol#881) is set pre-construction with a non-constant function or state variable:
- _taxFee
MetaToken._previousLiquidityFee (contracts/MetaToken.sol#884) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Low level call in Address.sendValue(address,uint256) (contracts/MetaToken.sol#316-328):
- (success) = recipient.call{value: amount}() (contracts/MetaToken.sol#323)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (contracts/MetaToken.sol#413-441):
- (success,returndata) = target.call{value: weiValue}(data) (contracts/MetaToken.sol#422-424)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

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.

Token is deployed only at one blockchain

Contract has 0% buy tax and 10% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.
