Multi Universe Central

In the contract `Ownable` the role `_owner` has authority over the functions shown in the diagram below. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and transfer or renounce the ownership.  In the contract `TaxableERC20` the role `_owner` has authority over the functions shown in the diagram below. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and set the fee rate, fee receiver, and determine which accounts are exempt from or subject to fees. 

All of the MUC tokens are sent to the contract deployer. This is a centralization risk because the deployer can distribute tokens without obtaining the consensus of the community. Any compromise to the address may allow a hacker to steal and sell tokens on the market, resulting in severe damage to the project.

The smart contract `TaxableERC20` allows for the setting of the transfer fee rate without an upper limit. This design flaw enables setting the transfer fee to any arbitrary value, up to 100%, which exposes the token holders to severe financial risk and makes the token susceptible to becoming a honeypot. ```solidity=844 function setTaxFeePerMille(uint256 taxFeePerMille) public onlyOwner { _setTaxRate(taxFeePerMille); } ```
