- Add simple_wallet.py with create, send, list commands - Compatible with existing keystore structure (/var/lib/aitbc/keystore) - Uses requests library (available in central venv) - Supports password file authentication - Provides JSON and table output formats - Replaces complex CLI fallbacks with working implementation - Update workflow to use simple wallet CLI - Cross-node deployment to both aitbc1 and aitbc This provides a fully functional CLI tool for wallet operations as requested, eliminating the need for Python script fallbacks.
