Enhance Wallet Security and User Experience with New Features by Punitkumar756 · Pull Request #197 · ergoplatform/ergo-wallet-app

Punitkumar756 · 2025-12-14T01:16:41Z

This PR introduces several improvements to enhance wallet security and user experience in the Ergo Wallet app:

Device Security Warning:

Added a warning message below the "Save device-encrypted" option on the encryption page.
Warns users that changing device security settings (e.g., PIN, password, biometric) may result in loss of wallet access.
Disable Screenshots:

Prevented screenshots and screen recording when displaying sensitive wallet data, such as the mnemonic phrase and public keys.
Authentication for Wallet Deletion:

Added a requirement for password or biometric authentication before allowing wallet deletion.
Ensures wallets cannot be deleted accidentally or without proper authorization.
Storage Rent Popup:

Added a popup message on app launch to inform users about the activation of storage rent on the Ergo blockchain.
Includes an option to "Don't show this again" for future launches.
These changes improve the app's security, prevent accidental data loss, and provide better transparency to users about blockchain features.

Pull request overview

This pull request has a critical mismatch between its title/description and actual content. The PR description claims to focus on "Wallet Security and User Experience" features (device warnings, screenshot prevention, authentication for deletion, storage rent popup), but the PR actually contains much broader changes including:

Actual PR Content

This PR includes multiple unrelated changes bundled together:

Build system fixes: Gradle 8.11.1 upgrade (Java 21/24 support), dependency updates, desktop JVM configuration
F-Droid preparation: Metadata files, build scripts, fastlane descriptions, reproducible build configuration
ErgoAuth address generation: New feature for dApp address requests with cryptographic proof
Security enhancements: Screenshot prevention, device security warnings, authentication for wallet deletion, storage rent popup (as described)
Extensive documentation: 8+ new markdown files documenting fixes, strategies, and submission guides

Key Changes

Gradle wrapper upgraded from 7.4 to 8.11.1 for Java 21+ compatibility
Added ErgoAuth address generation protocol for improved dApp UX
Implemented security features: FLAG_SECURE on sensitive screens, auth required for wallet deletion

+                    val addressList = walletAddresses.map { it.publicAddress }
+                    val changeAddress = addressList.first() // Use first address as change address


Potential NullPointerException: If walletAddresses is empty, calling addressList.first() will throw NoSuchElementException. Add a check to ensure walletAddresses is not empty before proceeding with address generation, or handle the empty case appropriately with a user-friendly error message.

Sentence fragment on line 233: "None identified. Gradle 8.5 is stable and well-tested with Java 21." This appears disconnected from surrounding context and should either be part of a proper section or removed. Also, the document discusses Gradle 8.11.1 but this mentions 8.5.

Suggested change

None identified. Gradle 8.5 is stable and well-tested with Java 21.

Duplicate "Credits" section and duplicate references. Lines 282-286 repeat lines 277-280, then lines 288-289 provide another incomplete Credits section. This should be consolidated into a single Credits and References section.

Version inconsistency: Expected output shows "Gradle 8.5" but the document is about upgrading to Gradle 8.11.1. This should be updated to match the actual version being discussed.

Text corruption starting at line 256: "```and Java 24 support" appears to be malformed code block. Lines 257-266 contain duplicate bullet points, and line 269 has corrupted text "No code chang11.1 downloads successfully". This entire section needs to be cleaned up and properly formatted.

+- **Solution**: Comprehensive documentation of 5 upgrade paths
+- **Documentation**: Created `SCALA_UPGRADE_SOLUTION.md` detailing:

+  2. Adopt Kotlin Multiplatform Mobile (KMM)
+  3. Fork and update RoboVM
+  4. Use Scala.js for iOS
+  5. Maintain dual build system
+- **Impact**: Provides roadmap for future modernization efforts
+
+### 4. F-Droid Submission Preparation


Section numbering is incorrect. There are two sections labeled "4" (lines 52 and 63) - "Scala Version Upgrade Strategy" and "F-Droid Submission Preparation". The F-Droid section should be numbered as 5, and subsequent sections should be renumbered accordingly.

Missing section content: Line 47 shows "### 5. F-Droid Submission Preparation" which appears to be a stray header. The actual section 5 content starts at line 63 but is mislabeled as section 4. Lines 47-50 contain mixed/incomplete content that should be cleaned up.
