## Progress Summary

| Component | Progress | Status |
|-----------|----------|--------|
| Web Wallet | 85% | Dilithium3 WASM + hybrid signatures complete |
| Desktop Wallet | 80% | Tauri + security implemented |
| Mobile Wallet | 0% | Planned (Flutter) |
| Explorer Frontend | 90% | Home, Blocks, TX, Address, DAG, Network, Gas pages complete |
