⚠️ Restore from SSSS: INCOMPLETE (needs delete wallet implementation)

Test Environment

  • Emulator: Samsung Galaxy S10 (Android 14)
  • Container: android-emulator on Lucy
  • Account: @testbot-elementx:sulkta.com
  • Network: Preprod Testnet

Wallet Under Test

  • Mnemonic: (stored in /root/.openclaw/workspace/memory/wallet-mnemonic.txt)
  • Expected Address: addr_test1qzl3rfpsnejf5wjey74yxz8jzduqzxfq3ze6xsgfcrrt03dlmpn40atetazzuywm6eseptz3eh9z7y7tevgtmujwy3ussnvev7

Backup Test (Step 3)

UI Flow

  1. Opened wallet panel via DM room → wallet icon
  2. Navigated to Settings tab
  3. Tapped "Backup to Matrix" button (NEW)
  4. Entered recovery key: b4a67d93602ec7741b743839c00c9cec902d8f709c6e22df98124606249e07b0
  5. Tapped "Backup" button

Result

✅ SUCCESS

Logcat output:

elementx: Wallet seed backed up to SSSS | WalletBackupServiceImpl.kt:37
elementx: Wallet backed up to SSSS successfully | WalletPanelPresenter.kt:176

Verification

Matrix account data stored at com.sulkta.cardano.wallet_seed:

{
  "encrypted": {
    "5b8ac89548308c51": {
      "iv": "PgPZ2DjObIJfdXVCa+diag",
      "ciphertext": "y1QvCtCJ+6WLmOLJTASU9zy5wuwIJveKNftS8hn9WuUvnudz6ICtwZFUbOPZpvpio3uq412L6BEWZd3Q3kIOfZT9RQhtCSTZFWOImOOrrigxdSx+MXxjIgqm+kc4zL8OLRLSbGYRamFSx6wXPEAzp+/V5vGD0IfsTOGzyGGg5tWcNxqHcmoNy9YTnBOGvafbCEBa3BPFYr86zIe3OPUB",
      "mac": "1ML2/NUoK6+Lm6MhwW6OOrtQ+g1nq0pExv78e2T5ruc"
    }
  }
}
  • Key ID 5b8ac89548308c51 matches expected recovery key ID ✅
  • Ciphertext is properly encrypted with SSSS ✅
  • MAC present for integrity verification ✅

Delete/Restore Test (Steps 4-5)

Blocker

The "Delete Wallet" button doesn't trigger a confirmation dialog or actual deletion in the current implementation. The event handler has placeholder comments:

WalletPanelEvent.DeleteWallet -> {
    // Show confirmation dialog - handled elsewhere
}

What's Needed

  1. Implement delete confirmation dialog in WalletPanelView
  2. Add actual delete logic in presenter (call keyStorage.deleteWallet())
  3. Detect existing SSSS backup on setup screen to offer restore option

Size: 220MB (arm64)

Next Steps

  1. Implement Delete Wallet - Add confirmation dialog and actual deletion
  2. Implement Restore Detection - Check for SSSS backup on wallet setup screen, offer restore option
  3. Test Full Round-Trip - Delete wallet → Restore from SSSS → Verify address matches
  4. Edge Cases - Test with wrong recovery key, corrupted backup, etc.
