In the `VIZToken` contract, the `mint()` function, designed to create new tokens, restricts the total supply to not exceed `_maxSupply`.

This could potentially increase the total supply beyond `_maxSupply`, leading to inflation and possible violation of the predefined token economics. --- Important Note: Certain identification and KYC procedures were attempted to be applied to the project team in order to better understand the centralization situation and potential risks of the project. Based on the collected information and further conducted investigation, the project passed the criteria with a certain amount of requirements satisfied for the investigation. Still we strongly advise end users to conduct further research and exercise due diligence before engaging with the project. It is crucial for end users to independently verify and assess all available information to make informed decisions.

In the contracts `VIZToken`, the role `_owner` has the authority to mint an arbitrary amount of tokens to an arbitrary address. Any compromise to the `_owner` account may allow a hacker to take advantage of this authority and mint a huge amount of tokens to themselves. The hacker could sell those tokens and cause the token price to drop. --- Important Note: Certain identification and KYC procedures were attempted to be applied to the project team in order to better understand the centralization situation and potential risks of the project.
