Most of the catalog is queryable for Optimism, from the blocks themselves to the daily activity of the projects that run on it.
The chain’s own record sits in the optimism dataset: one row per block, transaction, log and internal call. Everything above that sits in the catalog, where the Optimism rows are selected with chain_id = 'optimism'.
The section mirrors the catalog itself: the core entities, then the market verticals with data on Optimism.

Filtering
chain_id reads optimism wherever a catalog table carries a chain, so the same filter selects Optimism everywhere. Some shapes ask for something else. The asset tables key on the asset or its deployment, so the chain comes from dimensions.asset_tokens, as the query below does. Project and app totals span every chain a project runs on, so one chain’s share reads from metrics_project_chains and metrics_app_chains. A bridge transfer has a chain on each end and carries source_chain_id and destination_chain_id.
Every table splits by day: the raw and event tables on block_timestamp, the daily tables on timestamp. Bound that column in every query; without a bound the query reads the whole table.
