Can an Immutable Smart Contract Be Deleted or Removed from the Blockchain?

No, a smart contract, once deployed, cannot be deleted or removed from the blockchain in the traditional sense. Its code and transaction history are part of the immutable distributed ledger.

However, some platforms, like Ethereum, have a SELFDESTRUCT opcode that can remove the code and storage from a contract's address, but the transaction history remains. This function is often used to deactivate a contract and send its remaining funds to a designated address.

Even after self-destruction, the contract's address and past transactions are permanently recorded on the blockchain.
