+The architecture consists of five primary layers:
+
+- **User Layer**: Chess players and third-party developers
+- **Integration Layer**: SDK, wallets, and frontend interfaces  
+- **Platform Layer**: Multiple integrator platforms with custom configurations
+- **Ephemeral Rollup Layer**: High-speed execution environments for active games
+- **Solana L1 Layer**: Permanent state storage and settlement layer
