How to add custom networks ​

Besides the built-in Mainnet and Testnet, you can add your own networks to the Ultra Wallet extension, for example a local development node.

  1. Open the Ultra Wallet extension and click the network name under your account (or open the Menu, top right, and select Networks).

    Networks screen

  2. Click Add Custom Network, enter a Network Name and the Node URL of your Ultra node (see nodeos), then click Add Network.

    Add Custom Network form

  3. Select a network in the list to switch to it. Custom networks can also be edited or deleted from this screen.

The wallet checks a network before saving it:

  • The Node URL must use HTTPS. http://localhost and http://127.0.0.1 are allowed for local development.
  • Private and internal network addresses are refused.
  • The name must not imitate a built-in network (for example "Ultra Mainnet").
  • The wallet contacts the node and records its chain ID.

Websites cannot add networks

Only you can add a network, on this screen. Websites cannot add networks to your wallet. A connected website can switch the wallet to a network you have already added (extension 2.2.14+). See Ultra Wallet SDK → Accounts & Networks.
