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.
Transaction Fees
Please use the Hedera fee estimator to estimate your transaction fee cost
