Answer: The $UP contract is designed to be immutable, meaning that it cannot be changed or upgraded once it is deployed on the blockchain. This is an important feature of a smart contract, as it ensures that the code remains secure and cannot be altered by malicious actors. However, developers can still create new features and applications on top of the $UP contract, allowing them to build on the existing code and create new functionalities. This allows for the contract to evolve and adapt to the changing needs of users, while still maintaining the security of the code.
