# 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.

:::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.
:::

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).
