The AI engineer began by inheriting an Expo mobile app () and  as a reference. Initial efforts to run the existing app exposed Polkadot.js compatibility issues, leading to a shift towards a backend proxy for blockchain data. User frustration over repeated errors and lack of progress necessitated a complete rebuild from scratch, focusing on design, authentication via Supabase, and real-time blockchain data.

The rebuild progressed through several phases. Key challenges included fixing  hardcoding issues for mobile, correctly configuring network security (), handling Supabase setup (service role key,  table, email confirmation), and addressing UI/UX feedback (safe areas, widget sizing, wallet features, performance). The AI diligently integrated Cloudflare Turnstile for human verification (using test keys) and a test Polkadot wallet. The latest work focused on robust Settings functionality, including various sub-screens, and is currently addressing language localization and dark mode implementation, having just created the necessary i18n and ThemeContext files. The development process has been iterative, driven by continuous user feedback and troubleshooting, often involving  for complex environment issues.

The goal is to build the **PezkuwiChain Mobile App**, a Kurdish Digital Citizenship Platform. Key features include a Dual-Token Wallet (HEZ, PEZ), Governance (Welati - Voting), Digital Identity (KYC), Education Certificates, Trust Score, NFTs, Referral Program, Business Hub, and Token Exchange. It must support 6 languages (English, Kurdish Sorani/Kurmanji, Arabic, Turkish, Farsi). The technology uses React Native + Expo, TypeScript, Polkadot.js API (via backend proxy), and React Navigation.

The app is a complete rebuild, leveraging 's backend infrastructure. It requires multi-network connectivity, user-centric UI/UX (thumb-friendly, gesture-driven), and a localized, Kurdish-themed design (red, green, yellow, white gradient, Kurdistan sun logo). Core flows include Human Verification, Sign In/Sign Up with email verification (and optional phone for first 1000 users) via Supabase, and a Home Screen displaying user profile, Tiki count, Trust Score, QR code, Notifications, Settings, and a dynamic widget area. The Wallet Screen needs to show balances, transaction history, and 30 quick action buttons. All images must be Base64. The backend is FastAPI, extended for Supabase authentication. Phase 1 focused on initial setup and core wallet features, and subsequent phases are enriching settings, user experience, and functionality.

<code_architecture>
The application utilizes a monorepo structure:  (Expo React Native) and  (FastAPI).



-   : FastAPI backend, configured to connect to a local Polkadot node via localtunnel () for real HEZ/PEZ balances. Supabase integration added for authentication (signup/login) and profile updates (email, wallet, 2FA settings). Includes an endpoint for Cloudflare Turnstile verification.
-   : Stores , , , , , , . Critical for backend service configuration.
-   : Expo application configuration. Crucially updated to include network security configurations ( for Android,  for iOS) to resolve Network request failed errors on mobile.
-   : Manages frontend dependencies. Numerous packages added for UI/UX, authentication, image handling, biometrics, and internationalization.
-   : Root component. Manages global providers (, ), and integrates the main navigation stack. Updated to include new screens for settings, notifications, QR scanning.
-   : **New file.** Centralizes API URL () to prevent hardcoding , resolving Network request failed issues.
-   : **New file.** Created to manage internationalization (i18n) for multi-language support across the app.
-   : **New file.** Manages user authentication state, login, logout, and signup using the FastAPI backend and Supabase. Initially hardcoded , later fixed to use the centralized API URL.
-   : **New file.** Created to manage theme (dark/light mode) state globally.
-   : Initial screen for language selection. Redesigned with Kurdish theme. Navigation to  was initially faulty, then fixed.
-   : Integrates Cloudflare Turnstile for bot protection using a WebView. Faced multiple network issues due to  and  misconfiguration, which were debugged and fixed.
-   : Handles user Sign In/Sign Up. Uses  for calls to the backend. Also had  issues, which were resolved.
-   : Main dashboard. Features profile picture, Tiki/Trust Score, QR, Notifications, Settings, dynamic widget. Includes  for displaying real HEZ/PEZ balances (from test wallet), 12 quick action buttons (down from 30 for performance), and token list with images. Extensively modified for safe area padding and responsive design. Updated for profile pic upload via camera/gallery, navigation to QR, Notifications, Settings.
-   : Central hub for settings. Now includes navigation to , , , , , , , , and Sign Out. Biometric authentication toggle added.
-   Various new screens (, , , , , , , , , ) have been created to support the detailed settings functionality, mostly with placeholder/basic implementations, awaiting full logic integration.
</code_architecture>

<pending_tasks>
-   Implement the logic for LanguageSettingsScreen to dynamically change the app's language, ensuring it doesn't redirect the user to the start.
-   Implement the Dark Mode toggle functionality using  within SettingsScreen.
-   Fully implement Two-Factor Authentication (currently a placeholder).
-   Complete the logic for  (email update), , and .
-   Develop comprehensive content and functionality for , , and  (including FAQs and linking to  support).
-   Implement the full 30 quick action buttons on the Wallet screen with lazy loading/virtualized lists to avoid performance issues.
-   Activate wallet notifications and QR reader.

Immediately before this summary request, the AI engineer was addressing the user's latest deficiencies reported for Phase 2.1. Specifically, the user highlighted that:
1.  The language selection in  was non-functional and stuck to English, also resetting the user's navigation flow to the beginning of the app upon selection.
2.  The dark mode toggle was inactive.

To address these issues, the AI engineer initiated the implementation of a proper internationalization (i18n) and theme management system. The very last action taken was the installation of necessary packages for i18n (, , , , , , ) and the creation of two new configuration/context files:
-   : This file is intended to hold the configuration for handling multiple languages within the application, including language definitions and translation functions.
-   : This file is designed to provide a React Context for managing the application's theme, specifically enabling dark/light mode functionality and making it accessible globally.

The engineer's immediate next step, as indicated by the last message, is to further develop  to be truly functional, integrate the dark mode toggle into , and update  to wrap the application with the new . The goal is to ensure language changes are silent and don't disrupt the user's flow, and dark mode can be toggled effectively.

<optional_next_step>
Implement the language selection logic in  and the dark mode toggle in , then integrate  into .
