# parity

The `parity` namespace provides a limited subset of the OpenEthereum (formerly Parity) JSON-RPC API for compatibility with tooling that targets the original Parity client.

{% hint style="warning" %}
Only **one** method from the original OpenEthereum `parity_*` specification is implemented in Erigon. All other `parity_*` methods (account management, vault, signing, transaction queue, etc.) are not supported. Use the equivalent `eth_*` methods instead.
{% endhint %}

Enable the namespace with `--http.api=...,parity`.

For the full original OpenEthereum `parity_*` specification, see the [OpenEthereum JSON-RPC parity module documentation](https://openethereum.github.io/JSONRPC-parity-module) (archived).

| - | ------------- | ------------------- | ----------------------------------------------------------------------------------- |
| 1 | `address`     | `Address`           | The contract address to query storage for                                           |
| 2 | `quantity`    | `integer`           | Number of storage keys to return                                                    |
| 3 | `offset`      | `Bytes` (optional)  | Pagination offset — the storage key to start from                                   |
| 4 | `blockNumber` | `BlockNumberOrHash` | Block to query. Must be `"latest"` (other tags and block numbers are not supported) |

**Returns**

Array of storage key hashes (`Bytes[]`).
