Blockchain Balance Multi-Chain Enhancement

🎯 MULTI-CHAIN ENHANCEMENT COMPLETED - March 6, 2026

Status: ✅ BLOCKCHAIN BALANCE NOW SUPPORTS TRUE MULTI-CHAIN OPERATIONS

---

📊 Enhancement Summary

Problem Solved

The blockchain balance command previously had limited multi-chain support:

• Hardcoded to single chain (ait-devnet)
• No chain selection options
• False claim of "across all chains" functionality

Solution Implemented

Enhanced the blockchain balance command with true multi-chain capabilities:

• Chain Selection: --chain-id option for specific chain queries
• All Chains Query: --all-chains flag for comprehensive multi-chain balance
• Smart Defaults: Defaults to ait-devnet when no chain specified
• Error Handling: Robust error handling for network issues and missing chains

---

🔧 Technical Implementation

New Command Options

# Query specific chain
aitbc blockchain balance --address <address> --chain-id <chain_id>

# Query all available chains
aitbc blockchain balance --address <address> --all-chains

# Default behavior (ait-devnet)
aitbc blockchain balance --address <address>

Enhanced Features

1. Single Chain Query

aitbc blockchain balance --address aitbc1test... --chain-id ait-devnet

Output:

{
  "address": "aitbc1test...",
  "chain_id": "ait-devnet",
  "balance": {"amount": 1000},
  "query_type": "single_chain"
}

2. Multi-Chain Query

aitbc blockchain balance --address aitbc1test... --all-chains

Output:

{
  "address": "aitbc1test...",
  "chains": {
    "ait-devnet": {"balance": 1000},
    "ait-testnet": {"balance": 500}
  },
  "total_chains": 2,
  "successful_queries": 2
}

3. Error Handling

• Individual chain failures don't break entire operation
• Detailed error reporting per chain
• Network timeout handling

---

📈 Impact Assessment

✅ User Experience Improvements

• True Multi-Chain: Actually queries multiple chains as promised
• Flexible Queries: Users can choose specific chains or all chains
• Better Output: Structured JSON output with query metadata
• Error Resilience: Partial failures don't break entire operation

✅ Technical Benefits

• Scalable Design: Easy to add new chains to the registry
• Consistent API: Matches multi-chain patterns in wallet commands
• Performance: Parallel chain queries for faster responses
• Maintainability: Clean separation of single vs multi-chain logic

🔄 Comparison: Before vs After

Feature	Before	After
Chain Support	Single chain (hardcoded)	Multiple chains (flexible)
User Options	None	--chain-id, --all-chains
Output Format	Raw balance data	Structured with metadata
Error Handling	Basic	Comprehensive per-chain
Multi-Chain Claim	False	True
Extensibility	Poor	Excellent

🔗 Integration with Existing Multi-Chain Infrastructure

Consistency with Wallet Commands

The enhanced blockchain balance now matches the pattern established by wallet multi-chain commands:

# Wallet multi-chain commands (existing)
aitbc wallet --use-daemon chain list
aitbc wallet --use-daemon chain balance <chain_id> <wallet_name>

# Blockchain multi-chain commands (enhanced)
aitbc blockchain balance --address <address> --chain-id <chain_id>
aitbc blockchain balance --address <address> --all-chains

Chain Registry Integration

Current Implementation: Hardcoded chain list ['ait-devnet', 'ait-testnet']
Future Enhancement: Integration with dynamic chain registry

# TODO: Get from chain registry
chains = ['ait-devnet', 'ait-testnet']

---

🚀 Usage Examples

Basic Usage

# Get balance on default chain (ait-devnet)
aitbc blockchain balance --address aitbc1test...

# Get balance on specific chain
aitbc blockchain balance --address aitbc1test... --chain-id ait-testnet

# Get balance across all chains
aitbc blockchain balance --address aitbc1test... --all-chains

Advanced Usage

# JSON output for scripting
aitbc blockchain balance --address aitbc1test... --all-chains --output json

# Table output for human reading
aitbc blockchain balance --address aitbc1test... --chain-id ait-devnet --output table

---

📋 Documentation Updates

CLI Checklist Updated

File: docs/10_plan/06_cli/cli-checklist.md

Change:

# Before
- [ ] `blockchain balance` — Get balance of address across all chains (✅ Help available)

# After  
- [ ] `blockchain balance` — Get balance of address across chains (✅ **ENHANCED** - multi-chain support added)

Help Documentation

The command help now shows all available options:

aitbc blockchain balance --help

Options:
  --address TEXT     Wallet address  [required]
  --chain-id TEXT    Specific chain ID to query (default: ait-devnet)
  --all-chains       Query balance across all available chains
  --help             Show this message and exit.
