Adding New Networks to SubWallet


This tutorial assumes you have already completed the setup for SubWallet. If you have not please refer to the section above

SubWallet supports adding custom networks. This can be helpful for in-development networks such as the Subspace Network as we have regularly changing RPC endpoints and versions of testnets, and soon various domains. Below you will find a simple guide on how to add these new networks. Additionally we will try and keep an updated list of active RPC endpoints below for development.

RPC Endpoints
  • Gemini 3d Endpoint: wss://
  • Gemini 3e Endpoint: wss://
  1. Open SubWallet, Select the 3 Line menu in the top left of the wallet


  2. Inside the settings menu you will see the option to Manage Networks, click this.

  4. This will open the Import Network menu, where you will see a few options

    • Provider URL
    • Network Name
    • Symbol
    • Block explorer
    • Crowdloan URL

    The only option that is required is the Provider URL. You can add an explorer if you would like but it is not required. (The current Subspace Explorer is available here.

    You can refer to the RPC Endpoints above for available provider URLs for the Subspace Network.


  5. Fill in the provider URL, once you click out of this box it will check the URL and add the rest of the information, then click Save.

    • In this example we will be using wss://


  6. You will then be taken back to the network screen where you can then see your new network that was added.
