# Base

> Everything the catalog holds for Base, from raw blocks to project activity.

Most of the catalog is queryable for Base, from the blocks themselves to the daily activity of the projects that run on it.

The chain's own record sits in the `base` dataset: one row per block, transaction, log and internal call. Everything above that sits in the catalog, where the Base rows are selected with `chain_id = 'base'`.

The section mirrors the catalog itself: the core entities, then the market verticals with data on Base.

## Filtering

`chain_id` reads `base` in every catalog table that mentions a chain, so the same filter selects Base everywhere. Bridge transfers are the one exception: a transfer has a chain on each end and carries `source_chain_id` and `destination_chain_id` instead.

<Warning>
  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.
</Warning>

```sql theme={null}
select
    timestamp,
    asset_id,
    symbol,
    market_cap_circulating_total
from `metrics.asset_tokens_daily`
where chain_id = 'base'
  and timestamp >= timestamp('2026-08-01')
  and timestamp < timestamp('2026-08-02')
limit 100
```
