Dune Sim and Dune Analytics — on-chain analytics skill

This skill is the primary home for Dune-powered workflows in blockint: how to think, what to call when, and how to ship analytics that combine realtime Sim data with historical SQL where appropriate. It is not a thin link list—use it to structure tasks; open docs.sim.dune.com/llms.txt and openapi.json for exact parameters and auth as you implement.

Educational and integration guidance—users remain responsible for API keys, billing, and Terms.

Mental model: two engines

Rule of thumb: Need streaming or low-latency address/token views across many EVM chains or SVM (Solana / Eclipse, etc.) → start with Sim and chain-specific docs under chains/. Need long-horizon or custom aggregations across Dune SQL models → Analytics API and query execution docs.

When to use which surface (decision flow)

1. Single address or small set — balances, recent activity, NFTs, token metadata → Sim EVM or SVM endpoints (see overviews below).
2. Ongoing monitoring — balance or activity changes for a watchlist → Subscriptions / webhooks (create, update addresses, lifecycle per docs).
