**Step 3**: Scroll down the network list or type the name to find your custom network.

*In this example, we will manage the "**Filecoin - Mainnet**" network - an EVM network.*

Depending on what suits your needs, choose the appropriate tab:

{% tabs %}
{% tab title="Edit network information" %}
{% hint style="warning" %}
Once a network is imported onto SubWallet, you can only edit its information by:

* Adding another network's provider URL
* Adding the network's block explorer
  {% endhint %}

**Step 4**: Click the pencil icon to get to the Network detail screen.

{% hint style="info" %}
To add another provider URL, click on the "**+**" button at the upper right corner of the screen, then add your selected provider URL. Once done, click "**Save**".
