Delete & Restore Feature Implementation Results

Date: 2026-03-29
Branch: phase1-dev
Commits:

• da589ae78f - feat(wallet): complete SSSS round-trip with delete and restore
• ee439cb5a3 - fix(wallet): use full URL for account data check

Feature 1: Delete Wallet with Warning Dialog ✅

Implementation

• Added showDeleteConfirmation: Boolean state to WalletPanelState
• Created WalletDeleteConfirmationDialog.kt composable:
  • Large ⚠️ warning icon
  • Title: "Delete Wallet?"
  • Warning body about permanent deletion and backup importance
  • Checklist: "Written down your 24-word recovery phrase, OR Backed up to Matrix"
  • "Cancel" button (safe, dismisses)
  • "Delete Wallet" button (destructive, red)
  • Non-dismissible (onDismissRequest = {}, BackHandler blocks back press)
• Added events: DeleteWallet, ConfirmDeleteWallet, CancelDeleteWallet
• Wired deletion in presenter: calls keyStorage.deleteWallet(sessionId), then walletManager.clearState()
• After deletion, panel shows wallet setup screen

Files Modified

• WalletPanelState.kt - added showDeleteConfirmation field
• WalletPanelPresenter.kt - handle delete events
• WalletPanelView.kt - render dialog when showDeleteConfirmation=true
• WalletDeleteConfirmationDialog.kt - new composable (created)
• OverviewTabView.kt - updated preview with new state field
• strings.xml - added delete wallet strings

Feature 2: Restore from SSSS on Setup Screen ✅

Implementation

• Added hasBackupWithoutKey(): Result<Boolean> to WalletBackupService interface
• Implementation uses matrixClient.userIdServerName() to get homeserver domain
• Constructs full Matrix API URL: https://$serverName/_matrix/client/v3/user/$userId/account_data/$secretName
• Uses matrixClient.getUrl(url) to check if account data exists (without decryption)
• Added state fields: hasCloudBackup, isCheckingCloudBackup, cloudRestoreRecoveryKey, isRestoringFromCloud
• Added SetupStep.RESTORE_FROM_CLOUD step
• Added events: RestoreFromCloud, UpdateCloudRestoreRecoveryKey, ConfirmCloudRestore
• On setup init: silently checks hasBackupWithoutKey()
• If backup exists: shows "Restore from Matrix Backup" button below "Import Existing Wallet"
• Restore flow: user enters recovery key → decrypt mnemonic from SSSS → import wallet → show address

Files Modified

• WalletBackupService.kt (api) - added hasBackupWithoutKey() method
• WalletBackupServiceImpl.kt - implemented hasBackupWithoutKey()
• WalletSetupState.kt - added cloud backup state fields, RESTORE_FROM_CLOUD step
• WalletSetupPresenter.kt - check for backup on init, handle restore events
• WalletSetupView.kt - RestoreFromCloudContent composable, show button when hasCloudBackup

Round-Trip Test

To test the full round-trip:

1. Open app with existing wallet (should have backup at key 5b8ac89548308c51)
2. Go to Settings tab → tap "Delete Wallet"
3. Warning dialog appears → tap "Delete Wallet" to confirm
4. Wallet panel shows setup screen
5. "Restore from Matrix Backup" button should appear (if hasBackupWithoutKey detected it)
6. Tap restore → enter recovery key 5b8ac89548308c51
7. Wallet restores with address: addr_test1qzl3rfpsnejf5wjey74yxz8jzduqzxfq3ze6xsgfcrrt03dlmpn40atetazzuywm6eseptz3eh9z7y7tevgtmujwy3ussnvev7

Notes

• The hasBackupWithoutKey() check makes an authenticated HTTP request to the Matrix API
• If the check fails (network issues, etc.), it silently returns false and the button won't appear
• Users can always use "Import Existing Wallet" to manually enter their mnemonic as a fallback
• Delete dialog is non-dismissible - user must explicitly choose Cancel or Delete
