Trial: Email datashares-sales@dune.com or contact enterprise team Requirements:
  • GCP Project ID
  • Preferred region (US Central 1 or EU West 2)
  • Chains of interest

​
Sharing Identifiers

BigQuery uses dataset sharing for accessing Dune data:
  • Analytics Hub: Shared datasets appear in your project’s Analytics Hub
  • Direct sharing: We grant access to specific dataset IDs in your project

​
Principal Types

We need a “Principal” to grant access. This can be:
TypeFormatExample
Useruser:email@domain.comuser:bob@acme.com
Service AccountserviceAccount:name@project.iam.gserviceaccount.comserviceAccount:etl-sa@cust-proj.iam.gserviceaccount.com
Domaindomain:domain.comdomain:acme.com

Most common: provide your email address or a service account email. We can share complete blockchain history in seconds.
See GCP Principal Identifiers documentation for more details.

​
Data Types

BigQuery uses native types for blockchain data:

​
Addresses & Hashes

-- Query using BYTES
WHERE tx_hash = FROM_HEX('efb2e2c26974f72d9f3f04c693db73ecc679dd60')
-- Or STRING
WHERE tx_hash_hex = '0xefb2e2c26974f72d9f3f04c693db73ecc679dd60'

​
Large Integers

BigQuery’s BIGNUMERIC handles uint256/int256 natively: 
WHERE value > CAST('1000000000000000000000' AS BIGNUMERIC)

​
Event Logs

SELECT block_number, topics, data
FROM `project.ethereum.logs`
WHERE topics[OFFSET(0)] = FROM_HEX('ddf252ad...')

​
Query Optimization

  • Use block_time in WHERE clauses for partitioning
  • Select only needed columns
  • Tables are clustered by common query patterns
