## Technical Implementation

### **✅ Technical Benefits**


**Consistent Multi-Chain Pattern**:
- **Uniform Options**: All commands use `--chain-id` and `--all-chains` where applicable
- **Standardized Output**: Consistent JSON structure with query metadata
- **Error Resilience**: Robust error handling for individual chain failures

**Enhanced Functionality**:
- **Health Monitoring**: Chain-specific health checks with availability status
- **Sync Tracking**: Per-chain synchronization monitoring
- **Information Access**: Chain-specific blockchain metrics and information
- **Client Integration**: Proper chain context in coordinator API calls
