This commit brings a separation of concerns for the UI components involved in dApp interactions.
Issue: The UI components depend on the WalletConnectService and also on its dependencies like DAppsRequestHAndler. As a result the UI components have a hard dependency on the WalletConnect specifics and are incompatible with BC. This results in duplication of logic.
Issue: The UI components operate on WalletConnect specific JSON object. E.g. session objects, session proposal etc. As a result the UI is built around the WalletConnect message format.
Issue: The UI components operate on ListModel items received through functions and stored internally. Any change in the model would result in a crash.
Solution: Remove the WalletConnectService dependency from DAppsWorkflow. The DAppsWorkflow now operates with models, signals and functions. This is the first step in the broader refactoring. Moving the logic into the service itself will allow us to further refactor the WC and BC.
How does it work now:
Dependencies - The UI components have a dependency on models. SessionRequestsModel and DAppsModel.
Pairing - The pairing is initiated in the UI. On user input a pairingValidationRequested signal is emitted and the result is received as a function pairingValidated. If the url is valid the UI requests a pairingRequested. When the WalletConnectService is refactored we can go further and request only pairingRequested and to receive a pairingResult call as a function with the result. In the current implementation on pairingRequested we'll receive a connectDApp request.
Connecting dApps - The flow is initiated with connectDApp function. This call currently contains all the needed info as args. In the next step it could be replaced with a ConnectionRequests model. The connectDApp call triggered a connection popup if we're not currently showing one to the user. If we're currently showing one it will be queued (corner case). The connection can be accepted with connectionAccepted and rejected with connectionDeclined. Once the connection is accepted we're expecting a result connectionSuccessful or connectionFailed. The connectionSuccessful also expects a new id for the established connection.
Signing - The signing flow orbits around the SessionRequestsModel. Each item from the model will generate a popup showing the sign details to the user. Sign can be accepted or rejected using signRequestAccepted or signRequestRejected. No response is currently expected. The model is expected to remove the sign request item.
1. The DAppsListProvider needs to receive all the user accounts so that it can process all dapps the user is connected to (the dapps filtering based on selected account is an internal impl. detail)
2. Call `revokeSession` on disconnect only if the dapp cannot be found in the WC active sessions. There is some overlapping between Browser connector and Wallet connect because both operate on the same data stored in the DB. If Browser connector controller removes WC data, the WC disconnect flows cannot be successfully completed.
3. Reuse the same notification flow for Browser connector as it's used for WC
4. Fix dapp filtering when processing the dapps that will be displayed in the UI.
(cherry picked from commit 21227893c2)
1. Hiding DApps button on not supported wallet account selection
2. Filtering DApps in connected dApps list based on account selection
closes: #15589closes: #15647
Add helper function to filter out dApps with sessions that don't
have any supported account in the available accounts list.
Use helper function to filter out dApps connected on other profiles
when listing dApps in the dApps list.
When disconnecting an app only disconnect sessions for the current
profile.
Closes: #14888, #15707
Abstract WalletConnectSDK to make it testable
Implement WC service pairing test
Bring back DAppsWorkflow tests back to life and add a pair modal test
Updates: #14927
Things done here:
Integrate basic functionality for wallet connect in status-go
Update the list of dapps from the SDK
Retrieve the persistence dapps list from the backend as a fallback
if there is no connection and SDK can't be initialized
