# Contract

The `Contract` entity offers a normalized representation of the Casper Network [Contract](https://docs.casper.network/developers/json-rpc/types_chain/#contract) without including entry point hashes, which can be queried separately using the [Contract entry point](/rest-api/contract-entry-point.md) 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:
