clearabi - tron [Value: 20CU]
Creates a transaction that clears the stored ABI of a smart contract.
Use cases

Use cases

  • Remove a contract's public ABI, e.g. to obscure implementation details post-audit
Constraints

Constraints

  • Only the contract's owner_address can clear its ABI
  • This does not remove or change the contract's bytecode, only the stored ABI

Response

200
Creates a transaction that clears the stored ABI of a smart contract.

Response params

object
visibleboolean
Indicates whether addresses in this transaction are represented in base58 format (true) or hex format (false).
txIDstring
The unique transaction hash (transaction ID), computed as the SHA256 of raw_data.
raw_dataobject
The unsigned transaction body containing the contract instruction and blockchain reference data.
object
contractarray_of_objects
The list of contract instructions to be executed by this transaction.
object
parameterobject
The typed payload describing the specific contract call being made.
object
valueobject
The decoded fields of the contract — here, a request to wipe a deployed contract's stored ABI.
object
owner_addressstring
The address authorized to clear the contract's ABI (must match the contract's origin address), in hex format.
contract_addressstring
The address of the smart contract whose ABI is being cleared, in hex format.
type_urlstring
The fully qualified protobuf type identifier describing which contract schema `value` should be decoded with.
typestring
The human-readable name of the contract type being executed (here, ClearABIContract).
ref_block_bytesstring
The last two bytes of the reference block number, taken from the latest solidified block at the time the transaction was built, used for replay protection.
ref_block_hashstring
The last eight bytes of the reference block's hash, taken from the same solidified block, paired with ref_block_bytes for replay protection.
expirationinteger
Unix timestamp, in ms, after which this transaction is no longer valid; typically set to the construction timestamp plus 60,000 ms.
timestampinteger
Unix timestamp, in ms, marking the moment the transaction was constructed.
raw_data_hexstring
The hex-encoded protobuf serialization of raw_data, used as the actual payload to sign and broadcast.
