Yes, smart contracts can be destroyed using the selfdestruct function.
Smart contracts provide a self-destruct feature that allows them to destroy contracts on the blockchain system. However, for developers, it is a double-edged sword. On the one hand, the self-destruct feature allows developers to delete smart contracts from Ethereum and transfer ether in the event of an emergency, such as an attack. On the other hand, this feature may increase the complexity of development and provide an attack channel for attackers.
