Adding a custom network allows you to configure consensus and mirror node endpoints for a custom/private Hedera network. To set up a custom network, you will need to supply the Mirror Node Base URL. The application will then retrieve the list of consensus node endpoints using the Hedera Mirror Node's REST API.

Select Custom
Go to Settings → General, and under the Network section, select the Custom tab.
Enter Mirror Node Base URL
Provide the base URL of the mirror node for the custom network you'd like to connect to. Once entered, the application will fetch and display the list of available consensus nodes for the network.
