# Free onchain analytics with CryptoHouse and Goldsky

> Query Solana, Ethereum, and Base onchain datasets for free at crypto.clickhouse.com, a public ClickHouse instance powered by Goldsky Mirror pipelines.

<Warning>
  Mirror is Goldsky's previous-generation pipeline product. If you're building a new pipeline, use [Turbo](/turbo-pipelines/introduction) instead. See the [Mirror vs. Turbo comparison](/mirror-vs-turbo), or the [migration guide](/turbo-pipelines/migrate-from-mirror) if you have an existing Mirror pipeline.
</Warning>

We have partnered with [Clickhouse](https://clickhouse.com/) to allow you to interact with some onchain datasets for free at [crypto.clickhouse.com](https://crypto.clickhouse.com/).

As of today, users of CryptoHouse can query Solana blocks, transactions, token\_transfers, block\_rewards, accounts, and tokens for free. Similar datasets are available for Ethereum and Base. We plan to expand the data available and expose more blockchains in the coming months!

Remember that you can see more information about each dataset in our [reference](/chains/supported-networks#mirror) and [schemas](/reference/schema/non-EVM-schemas#solana) pages.
