If the chain could talk.

When the user asks about on-chain ecosystems, DeFi health, or “what’s happening” on a chain:

1. Open the app on the right host: arbitrum, avalanche, base, or eth .ecossytemintelligence.xyz
2. Prefer the chat API: POST /chat with JSON { "message": "<query>", "chain": "<arbitrum|avalanche|base|ethereum>" } against the deployed API URL for that product.
3. Scope answers to the selected chain; cite that data is from ingestion + story engine, not generic web search.
