End users work with the Wallet Gateway through its User UI: a web app the Wallet Gateway serves at its root URL. From it they log in, create and manage parties, review transactions, and approve requests from dApps. This guide covers logging in and managing parties in the UI. To drive the same operations from a script or backend, see Automate with the User API.
The dApp API is separate. dApps call it through the dApp SDK when a user connects a wallet; users never call it directly. See dApp API.

​
The User UI

The Wallet Gateway serves a web UI at its root URL (for example http://localhost:3030). Its main pages are:
PagePathWhat it does
Login/loginChoose a network and identity provider, then sign in (OAuth redirect or self-signed).
Parties/partiesList, create, and remove parties, and set the primary party. Default landing page.
Activities/activitiesList of activities and view their status and details.
Approve/approveReview and sign or reject a transaction a dApp requested.
Callback/callbackInternal OAuth redirect target after login.

​
Log in

  1. Open the User UI and go to Login or Connect.
  2. Select from the list of available CIP-0103-compliant providers or gateways. Or enter a custom remote gateway URL.
  3. By selecting the Wallet Gateway option, a network of choice will be prompted. This network is associated with the connected validator or node, which needs to be configured within the validator or node settings.

  1. Click Connect to authorize to view your parties.
    • OAuth / OpenID Connect: you are redirected to your provider and back.
    • Self-signed: a token is generated locally (development only).
  2. On success you land on Parties. Unauthenticated users are redirected to Login automatically whenever a page needs a session.
The networks and IDPs you can choose from are configured by the operator. To add more, an admin manages them on the Networks and Identity Providers pages or in the configuration file. See Networks & identity providers.

​
Create a party

A wallet is a Canton party the Wallet Gateway manages for you on one network, signed by one signing provider.
  1. Navigate to the Parties list
  2. Choose + New
  3. Provide the Party ID (or hint) for the wallet.
  4. Select the network the wallet belongs to.
  5. Select the signing provider that will hold the key and sign transactions for this wallet. See Signing providers.
add a new party
  1. Optionally mark it as your primary wallet.
  2. Choose Create party
Each wallet is tied to exactly one network and one signing provider, so you can keep different parties on different networks or custody providers side by side in the same Wallet Gateway.
By the Parties header, you may click the refresh icon to reload your party list. If there is a party that was created outside of the Wallet Gateway, it may still appear but unable to access; showing a disabled status.

​
Set the primary party

You can mark one wallet as primary. dApps that request your primary account receive this wallet by default, so set it to the party you transact with most. Change it at any time on the parties page.
  1. Locate the desired party card (newer party cards located at the bottom of the list)
  2. Select Set as primary
  3. Verify with a green Primary tag
navigating between parties
Changing your primary wallet changes which party dApps default to. Connected dApps are notified through the accountsChanged event and should re-read the primary account rather than caching it. See dApp API.

​
View activities

The Activities page lists transactions the Wallet Gateway has prepared, signed, or executed for your parties, with their status and details. Reviewing and approving transactions that dApps request happens on the Approve page — see Approve & sign transactions.

​
Changing wallet providers

  1. Select the hamburger icon on the top right and Logout.
  2. Click Login or Connect in the dApp UI to trigger the pop-up.
  3. Select a new provider to log into and follow its instructions.

​
Sessions and logout

When you log in, the Wallet Gateway issues a session (a JWT) that authorizes your later calls to the User and dApp APIs. Sessions are created on login and stored in the Wallet Gateway’s database. Log out from the layout control. Logout ends the session (removeSession), clears local auth state, and returns you to Login — or closes the window if the UI was opened as an approval popup.
Sessions live in the Wallet Gateway’s database. If the operator restores the database from a backup or loses it, active sessions may be invalidated and users must log in again. See Networks & identity providers.
