Contract

The Contract entity offers a normalized representation of the Casper Network Contract without including entry point hashes, which can be queried separately using the Contract entry point API. Additionally, this entity omits the contract's named keys but utilizes them for identifying the contract's type.

Properties

The Contract entity has the following properties:

Property	Type	Description
contract_hash	string(64)	Contract hash represented as a hexadecimal string. Unique contract identifier
contract_package_hash	string(64)	Hash of the contract package, this contract version is a part of, represented as a hexadecimal string
block_height	uint64	Height of the block in which the contract was deployed to the network
deploy_hash	string(64)	Hash of the deploy that deployed the contract to the network represented as a hexadecimal string
contract_type_id	uint8	Identifier representing the type of the contract, check the types list here
timestamp	uint16	Timestamp indicating when the contract was created
contract_version	uint16	Version number associated with the contract
is_disabled	bool	Indicates whether the contract is currently disabled
timestamp	datetime	Timestamp indicating when the contract was created
contract_version	uint16	Version number associated with the contract
is_disabled	bool	Indicates whether the contract is currently disabled
