Datashare brings Dune data directly into your data warehouse. Query blockchain data in your own environment with complete privacy and control.

​
What You Can Share

  • Dune’s data: Dune’s curated tables (1.5M+ tables, 100+ chains), set up by Dune in your Snowflake, BigQuery, or Databricks environment.
  • Your own tables: tables in your Dune namespace with change data feed enabled, registered with sync_datashare, for example from dbt. Delivered to Snowflake, Databricks, or S3. See dbt Connector + Datashare.
dbt Connector + Datashare is available only to existing customers of this offering and is no longer available to new customers. Learn more about Enterprise Datashare.

How Datashare Works

Datashare replicates Dune’s processed blockchain data directly into your cloud data warehouse: Datashare Architecture
  1. Data Replication: We keep live copies of Dune tables in your Snowflake, BigQuery, or Databricks environment, or in an S3 bucket
  2. Native Integration: Data appears as regular tables/datasets in your warehouse - no APIs or external connections
  3. Fresh Data: Automatic updates keep your data in sync with Dune’s platform
  4. Your Environment: Query using your warehouse’s native SQL, compute, and security controls
This is the same curated, decoded blockchain data that powers dune.com - optimized for analytics with proper data types and indexing.

​
What We Need From You

To set up datashare access, we need specific identifiers from your cloud environment:
Please provide your Snowflake data sharing account identifier so Dune can grant you access to a listing. To find this identifier log in to your Snowflake account and click at your user profile at the bottom of the screen > Account > View account details > Copy data sharing account identifier (you can view a visual path here). You can also run the following SQL command:
Then, share it with your Dune contact.
Required Information:
  • GCP Project ID (not project name - the unique ID)
  • Principal for access (user email, service account, or domain)
  • Preferred region (US Central 1 or EU West 2)
  • Chains of interest (optional - we can share all by default)
Principal Examples:
  • User: user:alice@company.com
  • Service Account: serviceAccount:etl-service@my-project.iam.gserviceaccount.com
  • Domain: domain:company.com (all users in domain)
Dune shares tables with your Unity Catalog metastore through Databricks-to-Databricks Delta Sharing.Required Information:
  • Sharing identifier of your Unity Catalog metastore, in the format <cloud>:<region>:<metastore uuid>
Run this in the workspace you will use to query the data:
See the Databricks guide for details.
S3 Export delivers your own tables, registered with sync_datashare (for example from dbt), to a Dune-managed S3 bucket. Dune’s curated dataset is not available on S3.Required Information:
  • Preferred AWS region: where the export bucket is created
  • Read access principal: either an IAM role ARN in your AWS account, or your AWS account ID
Dune provisions the bucket and grants your principal read access; you query the Iceberg tables directly from S3 with your own engine. See the S3 Export guide for details.

​
Setup Process

  1. Share Identifiers: Provide the required identifiers for your platform
  2. Access Configuration: We configure sharing permissions on our side
  3. Verification: We’ll confirm when data is available in your environment
  4. Support: Ongoing technical support for queries and optimization
Security Note: We only need identifiers to grant access - never passwords, keys, or other sensitive credentials.
