<figure><img src="/files/WiIcAJph4aGZGjKpZkWb" alt=""><figcaption></figcaption></figure>

### Purpose

To create the first end-to-end playable prototype including user interface, matchmaking, and complete game flow.

***

### Key Highlights

* React frontend deployed - Live alpha version with match lobby, staking interface, and result display screens
* ELO-based matchmaking system completed - Algorithm pairs players within ±100 rating points for balanced competition
* Player profile system operational - Tracks wallet addresses, ELO ratings, win/loss records, and match history
* PostgreSQL integration complete - Backend stores all match data, player statistics, and transaction records
* MetaMask wallet integration - Users can connect Web3 wallets and sign transactions directly from frontend
* Real-time game state updates - WebSocket connections provide live match updates and move synchronization
* Basic anti-abandonment measures - Players penalized for leaving matches without completion

***

### Why It Matters

* Enables skill-based fair pairing - ELO system ensures competitive matches between similarly skilled players
* UI/backend integration brings public demo readiness - Platform now functional for limited beta testing with real users
* Backend tracks comprehensive metrics - Data collection supports future analytics, balance adjustments, and user insights
* Web3 integration demonstrates value proposition - Users experience seamless crypto gaming without technical complexity

***

### Open Issues

* Disconnection during match causes state inconsistency - Network interruptions may result in desynchronized game states
* Frontend occasionally submits before backend validation - Race condition where UI updates faster than server verification
* Matchmaking queue times excessive - Limited user base creates long wait times for balanced matches
* Mobile responsiveness incomplete - Chess interface not optimized for smaller screen sizes

***

### Fixed

* Match result syncing improved - Enhanced communication between backend services and smart contract layer
* Signature validation errors reduced - Better error handling for malformed or invalid player signatures

***

### Next Steps

* Introduce match timeout and auto-forfeit logic - Implement system to handle player inactivity and abandoned games
* Begin comprehensive anti-cheat replay logging - Enhance move history storage with tamper-proof verification
* Deploy testnet Chess matches with live staking - Enable real token staking for beta testers using testnet TAPZI
* Optimize mobile user interface - Redesign game board and controls for smartphone and tablet users
