1  # Quick Discussion - Network Toggle (NO NEW FILES)
  2  
  3  ## ✅ What I Discovered
  4  
  5  ### 1. Testnet URLs (VERIFIED!)
  6  ```bash
  7  ✅ API:     https://query.decaf.testnet.espresso.network (TESTED - Block 5720691)
  8  ✅ Explorer: https://explorer.decaf.testnet.espresso.network (TESTED - WORKS)
  9  ✅ Caff:    https://rari.caff.testnet.espresso.network (CONFIRMED)
 10  ```
 11  
 12  ### 2. Existing Code (GREAT NEWS!)
 13  - ✅ NetworkProvider exists - just needs state
 14  - ✅ useNetwork hook exists - already working
 15  - ✅ useDualNetworkData() exists - supports multiple networks!
 16  - ✅ stats.tsx has "MAINNET" label - perfect spot for toggle
 17  
 18  ### 3. The Plan (NO NEW FILES!)
 19  **Only modify 5 existing files:**
 20  1. config.ts - add testnet config
 21  2. networkcontext.tsx - add switch function
 22  3. stats.tsx - add toggle button to existing header
 23  4. useNet.ts - support current network
 24  5. env.example - add testnet variables
