# Public Community Nodes

Demex utilizes public community nodes to server API data. Users can access a variety of public nodes through the node selection UI to interact with the blockchain.

If you are a node creator and wish to add your node to the default list on Demex, see [this repostitory](https://github.com/Switcheo/carbon-rpc-nodes).

## Guide

Follow these steps to connect to a public node on Demex:\
\
**Step 1:** Click on the network icon in the menu tab.

More nodes will be displayed once they have been added. Node rating depicts the stability and reliability of the node.&#x20;
{% endhint %}

### Failure to connect to the node

In the event that you are unable to connect to a public node on Demex, you can reach out to the respective node creator via Email or Telegram (if available on [GitHub](https://github.com/Switcheo/carbon-rpc-nodes)) to restore the node.

```
          "creator": {
              "description": "These are contact details of the creator",
            "name": "Another name",
            "telegram": "thisisausernametoo",
            "email": "testnet@example.com"
        }
    }
]
```

This approach fosters stronger community ties. Users can directly contact the node creator independently, expediting the recovery process in case of node failure.
