# Arthera Mainnet

## Indexing Arthera Mainnet Data with Envio via RPC

:::warning
RPC as a source is not as fast as HyperSync. It is important in production to source RPC data from reliable sources. We recommend our partners at [drpc.org](https://drpc.org). Below, we have provided a set of free endpoints sourced from chainlist.org. **We don't recommend using these in production** as they may be rate limited. We recommend [tweaking the RPC config](./rpc-sync) to accommodate potential rate limiting.

We suggest getting the latest from [chainlist.org](https://chainlist.org).

### Overview

Envio supports Arthera Mainnet through an RPC-based indexing approach. This method allows you to ingest blockchain data via an RPC endpoint by setting the RPC configuration.

### Defining Network Configurations

To use Arthera Mainnet, define the RPC configuration in your network configuration file as follows:

:::info
You may need to adjust more parameters of the [rpc configuration](/docs/v2/HyperIndex/rpc-sync) to support the specific rpc provider.
:::

```yaml
name: IndexerName # Specify indexer name
description: Indexer Description # Include indexer description
networks:
  - id: 10242 # Arthera Mainnet
    rpc_config:
      url: https://rpc.arthera.net
    start_block: START_BLOCK_NUMBER # Specify the starting block
    contracts:
      - name: ContractName
        address:
          - "0xYourContractAddress1"
          - "0xYourContractAddress2"
        events:
          - event: Event # Specify event
          - event: Event
```
