`ERC20ToGenerateNftFraccion` is open for anyone to mint to any address

vincent71399

Description:

The ERC20ToGenerateNftFraccion contract has a mint function that allows anyone to mint tokens to any address.
making the total supply of the token inconsistent with the actual amount of NFTs divided.

function mint(address to, uint256 amount) public {
require(msg.sender == owner, "only owner can mint");
_mint(to, amount);
}

Impact:

currently tokenDivider uses local state to manage the fractional token balance, this free mint does not directly break the function,
but recommend to remove this function to avoid potential misuse.

Recommended Mitigation:

remove the mint function in ERC20ToGenerateNftFraccion contract, instead, mint the token in the constructor. So the total supply of the token is fixed at the actual amount of NFTs divided.
