+
+## Commands
+
+### 1. Create Wallet
+Create a new encrypted wallet with automatic key generation.
+
+```bash
+python /opt/aitbc/cli/simple_wallet.py create --name <wallet-name> --password-file <path-to-password-file>
+```
+
+**Examples:**
+```bash
+# Create wallet with password file
+python /opt/aitbc/cli/simple_wallet.py create --name my-wallet --password-file /var/lib/aitbc/keystore/.password
+
+# Create wallet with interactive password
+python /opt/aitbc/cli/simple_wallet.py create --name my-wallet
+```
+
+**Output:**
+```
+Wallet created: my-wallet
+Address: ait1abc123def456...
+Keystore: /var/lib/aitbc/keystore/my-wallet.json
+Wallet address: ait1abc123def456...
+```
+
+### 2. Send Transaction
+Send AIT coins from one wallet to another with automatic signing.
+
+```bash
+python /opt/aitbc/cli/simple_wallet.py send --from <sender-wallet> --to <recipient-address> --amount <amount> --password-file <path-to-password-file>
+```
+
+**Examples:**
+```bash
+# Send 1000 AIT with default fee
+python /opt/aitbc/cli/simple_wallet.py send --from genesis --to ait1abc123... --amount 1000 --password-file /var/lib/aitbc/keystore/.password
+
+# Send with custom fee and RPC URL

+python /opt/aitbc/cli/simple_wallet.py list --format table
+
+# JSON format (machine-readable)
+python /opt/aitbc/cli/simple_wallet.py list --format json
+```
+
+### Remote Node Operations
+
+Connect to different RPC endpoints:
+
+```bash
+# Local node
+python /opt/aitbc/cli/simple_wallet.py balance --name my-wallet --rpc-url http://localhost:8006
+
+# Remote node
+python /opt/aitbc/cli/simple_wallet.py balance --name my-wallet --rpc-url http://10.1.223.40:8006
+```
+
+### Password Management
+
+Multiple password input methods:
+
+```bash
+# Password file
+python /opt/aitbc/cli/simple_wallet.py send --from wallet --to address --amount 100 --password-file /path/to/password
+
+# Interactive password
+python /opt/aitbc/cli/simple_wallet.py send --from wallet --to address --amount 100
+
+# Direct password (not recommended for production)
+python /opt/aitbc/cli/simple_wallet.py send --from wallet --to address --amount 100 --password mypassword
+```
+
+## Common Workflows
+
+### 1. Complete Wallet Setup
+```bash
+# Create wallet
+python /opt/aitbc/cli/simple_wallet.py create --name my-wallet --password-file /var/lib/aitbc/keystore/.password
+
+# Get wallet address
+WALLET_ADDR=$(python /opt/aitbc/cli/simple_wallet.py balance --name my-wallet --format json | jq -r '.address')
+
+# Check balance
+python /opt/aitbc/cli/simple_wallet.py balance --name my-wallet
+```
+
+### 2. Transaction Workflow
+```bash
+# Check sender balance
+python /opt/aitbc/cli/simple_wallet.py balance --name sender-wallet
+
+# Send transaction
+python /opt/aitbc/cli/simple_wallet.py send --from sender-wallet --to $WALLET_ADDR --amount 1000 --password-file /var/lib/aitbc/keystore/.password
+
+# Monitor transaction
+python /opt/aitbc/cli/simple_wallet.py transactions --name sender-wallet --limit 3
+
+# Check recipient balance
+python /opt/aitbc/cli/simple_wallet.py balance --name recipient-wallet
+```
+
+### 3. Network Monitoring
+```bash
+# Check network status
+python /opt/aitbc/cli/simple_wallet.py network
+
+# Check chain information
+python /opt/aitbc/cli/simple_wallet.py chain
+
+# List all wallets
+python /opt/aitbc/cli/simple_wallet.py list
+
+# Check all wallet balances
+for wallet in $(python /opt/aitbc/cli/simple_wallet.py list --format json | jq -r '.[].name'); do
+  echo "Wallet: $wallet"
+  python /opt/aitbc/cli/simple_wallet.py balance --name $wallet
+  echo "---"
+done
+```
+
+## Cross-Node Operations
+
+### aitbc1 to aitbc Operations
+```bash
+# On aitbc1 - check network status
+python /opt/aitbc/cli/simple_wallet.py network
+
+# On aitbc - check network status
+ssh aitbc 'python /opt/aitbc/cli/simple_wallet.py network'
+
+# Send from aitbc1 to aitbc wallet
+python /opt/aitbc/cli/simple_wallet.py send --from genesis --to $AITBC_WALLET_ADDR --amount 1000 --password-file /var/lib/aitbc/keystore/.password
+
+# Check balance on aitbc
+ssh aitbc "python /opt/aitbc/cli/simple_wallet.py balance --name aitbc-user"
+```
+
+## Error Handling
+
+The CLI provides comprehensive error handling:
+
+- **Wallet Not Found**: Clear error message when wallet doesn't exist
+- **Password Errors**: Proper password validation and error messages
+- **Network Errors**: RPC connectivity issues with helpful messages
+- **Transaction Errors**: Detailed transaction failure information
+- **JSON Parsing**: Graceful handling of malformed responses
+
+## Security Best Practices
+
+1. **Password Management**: Use password files instead of command-line passwords
+2. **File Permissions**: Ensure keystore files have proper permissions (600)
+3. **Network Security**: Use HTTPS for RPC endpoints in production
+4. **Backup**: Regularly backup keystore files
+5. **Validation**: Always verify transaction details before sending
+
+## Integration with Scripts
+
+The CLI is designed for easy integration with shell scripts:
+
+```bash
+#!/bin/bash
+# Get wallet balance in script
+BALANCE=$(python /opt/aitbc/cli/simple_wallet.py balance --name my-wallet --format json | jq -r '.balance')
+
+if [ "$BALANCE" -gt "1000" ]; then
+  echo "Sufficient balance for transaction"
+  python /opt/aitbc/cli/simple_wallet.py send --from my-wallet --to $RECIPIENT --amount 1000 --password-file /var/lib/aitbc/keystore/.password
+else
+  echo "Insufficient balance: $BALANCE AIT"
+fi
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Permission Denied**: Check file permissions on keystore directory
+2. **Connection Refused**: Verify RPC service is running
+3. **Invalid Password**: Ensure password file contains correct password
+4. **Wallet Not Found**: Verify wallet name is correct
+
+### Debug Mode
+
+Add verbose output for debugging:
+
+```bash
+# Enable debug output (if implemented)
+python /opt/aitbc/cli/simple_wallet.py --debug balance --name my-wallet
+```
+
+## Future Enhancements
+
+Planned features for future releases:
+
+- **Batch Operations**: Send multiple transactions in one command
+- **Smart Contracts**: Deploy and interact with smart contracts
+- **Staking**: Delegate and undelegate tokens
+- **Governance**: Participate in governance proposals
+- **NFT Support**: Create and manage NFTs
+- **Multi-signature**: Create and manage multi-sig wallets
+
+## Support
+
+For support and issues:
+
+1. Check the error messages for specific guidance
+2. Verify network connectivity and service status
+3. Review this documentation for proper usage
+4. Check system logs for additional error details
