Venator Universe

We express our gratitude to the Venator Universe team for the collaborative engagement that enabled the execution of this Smart Contract Security Assessment.

The VNT token is utilized both in the in-game market and on external exchanges. It is a token with a limited total supply, ensuring its scarcity and value. Players can find VNT tokens inside Dungeon Chests within the game, making it a valuable in-game currency. These tokens facilitate the buying and selling of items between players.

The VNT ecosystem consists of two primary smart contracts: VNTPreSale and VenatorToken. These contracts work together to manage the pre-sale, distribution, and utility of VNT tokens within the game and external markets.

VNTPreSale Contract

The VNTPreSale contract is responsible for managing the pre-sale event where users can purchase VNT tokens using USDC. The key features of this contract include:

• Token Purchase: Users can buy VNT tokens during the sale period by paying in USDC. The price is set at 0.22 USDC per VNT.

• Sale Period Management: The contract enforces the sale start and end times, ensuring that token purchases can only occur within the specified period.

• Lock and Release Mechanism: Tokens purchased during the pre-sale are locked for an initial period of 4 months. After the lock period, 10% of the tokens are released each month over the next 10 months.

• Event Emissions: The contract emits events for significant actions such as token purchases, token releases, and updates to critical contract parameters.

VenatorToken Contract

The VenatorToken contract implements the ERC20 standard and includes additional functionalities such as pausing transfers, burning tokens, and banning addresses. Key features of this contract include:

• Total Supply Management: The contract ensures a maximum supply of 100,000,000 VNT tokens.

• Minting: The contract allows the owner to mint new tokens, up to the maximum supply.

• Burning: Users can burn their tokens, reducing the total supply.

• Pausing: The contract owner can pause and unpause all token transfers, useful for emergency situations.

• Address Ban/Unban: The contract owner can ban and unban addresses, preventing them from transferring or receiving tokens.

Privileged roles

The system has the owner role that has the authority to perform administrative and sensitive operations within the contracts.

VNTPreSale Contract:

• Set Sale Parameters: The owner can set or update the start and end timestamps of the sale, token price, lock period, and other critical parameters.

• Update Token Addresses: The owner can update the addresses of the VNT and USDC tokens.

• Update Bank Address: The owner can change the VNT bank address where tokens are held for the pre-sale and release.

• Emergency Functions: The owner can pause or unpause the sale if required.

VenatorToken Contract:

• Minting: The owner can mint new VNT tokens up to the maximum supply.

• Pausing: The owner can pause and unpause all token transfers.

• Banning/Unbanning Addresses: The owner can ban addresses from transferring or receiving tokens and later unban them.

• Emergency Functions: The owner can implement measures such as pausing all contract functions if a critical issue arises.
