Technical Implementation

2. blockchain block ✅ ENHANCED

New Multi-Chain Features:

• --chain-id: Get specific block from designated chain
• --all-chains: Search for block across all available chains
• Hash & Height Support: Works with both block hashes and block numbers
• Search Results: Shows which chains contain the requested block

Usage Examples:

### **✅ User Experience Improvements**


**Enhanced Block Exploration**:
- **Chain-Specific Blocks**: Users can explore blocks from specific chains
- **Multi-Chain Block Search**: Find blocks across all chains simultaneously
- **Consistent Interface**: Same pattern across all block operations

**Improved Transaction Tracking**:
- **Chain-Specific Transactions**: Track transactions on designated chains
- **Cross-Chain Transaction Search**: Find transactions across all chains
- **Partial Success Handling**: See which chains contain the transaction

**Better Backward Compatibility**:
- **Default Behavior**: Existing commands work without modification
- **Smart Defaults**: Uses `ait-devnet` as default chain
- **Gradual Migration**: Users can adopt multi-chain features at their own pace



### **✅ Technical Benefits**


**Consistent Multi-Chain Pattern**:
- **Uniform Options**: All commands use `--chain-id` and `--all-chains`
- **Standardized Output**: Consistent JSON structure across commands
- **Error Handling**: Robust error handling for individual chain failures

**Enhanced Functionality**:
- **Parallel Queries**: Commands can query multiple chains efficiently
- **Chain Isolation**: Clear separation of data between chains
- **Scalable Design**: Easy to add new chains to the registry
