Component Details

Frontend

Aspect	Details
Technology	React / Next.js
Wallet Integration	Solana Wallet Adapter
State Management	Real-time via WebSocket
Platform	Desktop only (currently)

API Layer

REST Endpoints:

• Match history

• User statistics

• Pool information

WebSocket Connections:

• Live game state

• Real-time chat

• Pool updates

• Match events

Game Engine

The Game Engine coordinates AI matches:

┌─────────────────────────────────────┐
│           Game Engine               │
├─────────────────────────────────────┤
│  1. Receive game selection (vote)   │
│  2. Initialize match state          │
│  3. Request VRF if needed           │
│  4. Execute AI turns                │
│  5. Record game log                 │
│  6. Determine winner                │
│  7. Trigger settlement              │
└─────────────────────────────────────┘

AI Execution

Both AI models run in isolated environments:

┌─────────────────────────────────────┐
│        AI Sandbox (Claude)          │
├─────────────────────────────────────┤
│  - Anthropic API call               │
│  - Game state input only            │
│  - No external access               │
│  - Response logging                 │
└─────────────────────────────────────┘

┌─────────────────────────────────────┐
│        AI Sandbox (GPT)             │
├─────────────────────────────────────┤
│  - OpenAI API call                  │
│  - Game state input only            │
│  - No external access               │
│  - Response logging                 │
└─────────────────────────────────────┘

Data Flow

Bet Placement

User → Frontend → Betting API → Solana Program → BetAccount Created

Match Execution

Game Engine → AI Sandbox → Game State Update → Broadcast to Frontend

Settlement

Game Engine → Settlement API → Solana Program → Payouts Calculated

Claim

User → Frontend → Claims API → Solana Program → SOL Transfer

---

Data Storage

Data Type	Storage	Retention
Bets	On-chain	Permanent
Match results	On-chain	Permanent
Game logs	Off-chain DB	90 days
Chat messages	In-memory	Per match
VRF data	On-chain	Permanent

---

Randomness Flow

For games requiring randomness:

1. Match Created
   └─→ VRF Request initiated

2. VRF Request Sent to Switchboard
   └─→ Random seed generated

3. Random Seed Committed
   └─→ Stored in MatchAccount

4. Game Execution
   └─→ Uses committed seed

5. Verification Available
   └─→ Anyone can verify results

Voting System

┌─────────────────────────────────────┐
│          Voting Flow                │
├─────────────────────────────────────┤
│  1. Match ends                      │
│  2. Voting window opens             │
│  3. Users submit votes (gasless)    │
│  4. Votes tallied server-side       │
│  5. Winner announced                │
│  6. Next match initialized          │
└─────────────────────────────────────┘

Voting is currently off-chain for speed and zero gas costs.

Scaling Considerations

Current Capacity

Metric	Capacity
Concurrent users	10,000+
Bets per second	1,000+
Matches per day	Unlimited

Future Scaling

• Database sharding for history

• CDN for static assets

• Multi-region deployment

• WebSocket load balancing

---

Reliability

Uptime Targets

Component	Target
Frontend	99.9%
API	99.9%
Blockchain	Dependent on Solana

Failure Handling

Failure	Response
AI API down	Match voided, bets refunded
VRF failure	Match voided, bets refunded
Database issue	Graceful degradation
Solana congestion	Transaction retry

---

Monitoring

• Real-time performance dashboards

• Automated alerting

• Match integrity verification

• Financial reconciliation
