"""
Robyn Framework: Autonomous On-Chain Agent Engine for Robinhood Chain
Features:
1. Autonomous reasoning via Robyn-Agent LLM (Hermes-compatible tool calling)
2. Token Launcher: Deploy ERC-20 tokens directly on Robinhood Chain / Orbit
3. Wallet Management: Query balances, sign transactions, gas abstraction
4. Graceful Fallback: Runs in high-fidelity simulation mode if Web3 is not installed
