The Data Hub is Dune’s web-based workspace where you query blockchain data with SQL, build visualizations, assemble dashboards, and share insights with your team or the public. It is one of several ways to work with Dune’s data — alongside the Data API, dbt integration, BI tool connectors, and Datashare. Data transformations on Dune

Prerequisites

  • Dune Account: Sign up here if you do not already have one.
  • Basic SQL Knowledge: Dune uses DuneSQL, a SQL dialect compatible with TrinoSQL. If you are new to SQL, start here.

What You Can Do

Write and Run Queries

Use the Query Editor to write SQL against blockchain data, add parameters, and schedule automated runs.

Visualize and Present Results

Turn query results into charts, counters, tables, and interactive dashboards.

Automate and Monitor

Schedule queries and dashboards to refresh automatically. Set up alerts for email or webhook notifications.

Share and Embed

Share dashboards by URL, embed live visualizations on any website, or export data via CSV and API.

Import and Export Data

Upload your own CSV datasets to join with blockchain data. Export query results in CSV or JSON.

Decode Smart Contracts

Submit contracts for decoding to create structured, queryable tables from raw transaction bytecode.

Manage Your Team

Create team workspaces, assign roles, share credits, and configure SSO for your organization.

Search and Discover

Find dashboards, queries, and analysts across Dune using search, discovery, and advanced filters.

Quick Start

Get from zero to a published dashboard in five minutes:
  1. Create a query — Open the Query Editor and write SQL. For example, daily Ethereum active addresses:
SELECT
  date_trunc('day', block_time) AS time,
  COUNT(DISTINCT "from") AS active_senders
FROM ethereum.transactions
WHERE block_time > DATE '2024-01-01'
GROUP BY 1
ORDER BY 1
  1. Run and save — Click Run to execute, then Save to persist your query.
  2. Add a visualization — Click New Visualization, choose a chart type, and configure your axes.
  3. Build a dashboard — Go to Create > New Dashboard, name it, then add your visualization as a widget.
  4. Share it — Copy the dashboard URL or use the Share button to embed it externally.
