## 🧪 **Testing Requirements**

### **Standard Multi-Chain Test Pattern**
Each enhanced command should have tests for:
1. **Help Options** - Verify `--chain-id` and `--all-chains` options
2. **Single Chain Query** - Test specific chain selection
3. **All Chains Query** - Test comprehensive multi-chain query
4. **Default Chain** - Test default behavior (ait-devnet)
5. **Error Handling** - Test network errors and missing chains

### **Test File Naming Convention**
