Yes, smart contracts can be destroyed using self-structuring functionality.
Smart contracts provide a self-structuring functionality that allows them to cancel contracts on the blockchain system. However, it is a double-edged sword for developers. On the one hand, the self-structuring functionality allows developers to remove smart contracts from Ethereum and transfer Ether in the event of an emergency, such as an attack. On the other hand, this functionality can add to the complexity of development and provide an attack channel for attackers.
