Delete a smart contract

A transaction that deletes a smart contract from a Hedera network. Once a smart contract is marked deleted, you will not be able to modify any of the contract's properties. **** If a smart contract did not have an admin key defined, you cannot delete the smart contract. You can verify the smart contract was deleted by submitting a smart contract info query to the network. If a smart contract has an associated hbar balance, you will need to transfer the balance to another Hedera account.
Transaction Signing Requirements
  • If the admin key was defined for the smart contract it is required to sign the transaction.
  • The client operator's (fee payer account) private key is required to sign the transaction.
