Wallet Connect Integration

TODO

• test namespaces implementation https://se-sdk-dapp.vercel.app/

Design questions

• Do we report disabled chains? Update session in case of enabled/disabled chains?
• User error workflow: retry?
• Check the Auth request for verifyContext https://docs.walletconnect.com/web3wallet/verify
• What description and icons to use for the app? See metadata parameter in Web3Wallet.init call

WalletConnect SDK management

Install dependencies steps by executing commands in this directory:

• update the package.json versions and run npm install
  • alternatively
    • use the command npm install <package-name>@<version/latest> --save for individual packages
    • or to update to the latest run npm update in here
  • these commands will also create or update a package-lock.json file and populate the node_modules directory
• update the bundle.js file by running npm run build
  • the result will be embedded with the app and loaded by WalletConnectSDK.qml component
• add the newly generated files to index git add --update . to include in the commit

Testing

Use the web demo test client https://react-app.walletconnect.com/ for wallet pairing and https://react-auth-dapp.walletconnect.com/ for authentication

Dev - to be removed

To test SDK loading add the following to ui/app/mainui/AppMain.qml

import AppLayouts.Wallet.stores 1.0 as WalletStores
import AppLayouts.Wallet.views.walletconnect 1.0

// ...

StatusDialog {
    id: wcHelperDialog
    visible: true

    WalletConnect {
        SplitView.preferredWidth: 400
        SplitView.preferredHeight: 600

        backgroundColor: wcHelperDialog.backgroundColor

        controller: WalletStores.RootStore.walletConnectController
    }

    clip: true
}

Initial setup

npm install --save @walletconnect/web3wallet
npm run build
# npm run build:dev # for development

• Do we report all chains and all accounts combination or let user select?
  • Wallet Connect require to report all chainIDs that were requested
  • Answer: We only report the available chains for the current account. We will look into adding others to he same session instead of requiring a new link
• Can't respond to sign messages if the wallet-connect dialog/view is closed (app is minimized)
  • Only apps that use deep links are expected to work seamlessly
  • Also the main workflow will be driven by user
• Allow user to disconnect session? Manage sessions?
  • Yes, in settings
• Support update session if one account is added/removed?
  • Not at first
• User awareness of session expiration?
  • Support extend session?
    • Yes
