Datashare FAQs - Dune Docs

How does datashare work technically?

Snowflake: Uses Snowflake’s native data sharing - data stays in our account but appears as tables in yours. Zero storage costs, only compute charges.BigQuery: We replicate data to shared datasets in your GCP project. Data is copied to your region for performance.Both provide the same curated blockchain data that powers dune.com.

What identifiers do I need to share with Dune?

Snowflake: Account locator (e.g., ABC12345.US-EAST-1) - found in your Snowflake URLBigQuery: GCP Project ID and a Principal (your email, service account, or domain)We never need passwords or sensitive credentials - just sharing identifiers.

How do I get started?

Snowflake: Self-service via Snowflake Marketplace for 30-day trialBigQuery: Email datashares-sales@dune.com with your GCP Project IDEnterprise: Visit dune.com/enterprise

What platforms do you support?

Snowflake (marketplace access, all regions)
BigQuery (custom setup, US Central 1 & EU West 2)

How fresh is the data?

Standard: 24 hours for most tables Enterprise: Hourly updates available Real-time: Some key tables update every few minutesFreshness varies by chain and table type.

Is it the same data as Dune's platform?

Yes, identical curated data. Data types are optimized for each platform:

BigQuery: Uses BIGNUMERIC for large integers, BYTES for addresses
Snowflake: Uses VARBINARY for addresses/hashes, DOUBLE for calculations

Can I join with my existing data?

Yes - that’s the main benefit! Query blockchain data alongside your internal datasets using your warehouse’s native SQL.

Do you see my queries or data?

No. You query in your own warehouse environment. Dune cannot see your queries, results, or any data you join with ours.

What does it cost?

Trials: Free (Snowflake 30 days, BigQuery by request) Production: Contact sales for pricing Compute: You pay your cloud provider’s standard rates for querying

[Snowflake] Get button didn't work?

Click “Get” twice if needed. Snowflake sometimes requires:

First click: Copies data to your region
Second click: Adds share to your account

[BigQuery] How do I find shared datasets?

Shared datasets appear in your BigQuery console under your project. Look for datasets with names like dune_ethereum or dune_polygon.
