Dune

Dune is a blockchain data platform that turns raw on-chain activity into queryable, shareable intelligence. It solves a fundamental problem in crypto: the data generated by hundreds of blockchains is publicly available but largely inaccessible without significant infrastructure — Dune indexes it all, normalizes it, and puts it behind a SQL interface anyone can use.

Core Mechanism

At its foundation, Dune runs a distributed query engine — internally called Dune Engine V2 — that processes data from 100+ blockchains in parallel. Users write SQL (a custom dialect called DuneSQL) against indexed tables that represent blocks, transactions, contract calls, token transfers, and decoded protocol events. Queries run in the browser against live data, with results returned in seconds to minutes depending on complexity and data volume. The platform currently indexes over three petabytes of blockchain data.

What distinguishes Dune from running your own node or indexer is the degree of work done before the query. Raw data is decoded, normalized, and — through the Spellbook layer — transformed into curated datasets covering common concepts like DEX trading volumes, NFT sales, and token flows. Spellbook is an open-source dbt repository where the Dune community collectively builds and maintains these higher-order models. Each Spellbook model is a SQL query that outputs a reusable table, making complex multi-protocol aggregations as simple as querying a single view.

Key Products

Data Hub is Dune's primary interface — a web application where analysts write SQL, visualize results, and publish interactive dashboards. The platform hosts over 200,000 dashboards and more than 6.5 million queries, forming a community archive of on-chain research that others can fork, extend, and build on. Popular dashboards tracking DEX volumes, stablecoin flows, NFT markets, and validator economics have become reference sources across the crypto industry.

Datashare connects Dune's indexed datasets directly to enterprise data warehouses. Organizations running Snowflake, BigQuery, or Databricks can subscribe to Dune's normalized blockchain tables and receive them as a data stream, integrating on-chain activity into existing analytics pipelines without building their own indexing infrastructure.

Data API provides programmatic access to query results. Developers can trigger queries and retrieve results via REST API, enabling on-chain data to flow into applications, dashboards, and monitoring tools without manual intervention.

dbt Connector allows data engineers to integrate Dune query outputs into production dbt transformation workflows, bridging the gap between blockchain data and standard data engineering practice.

The platform also supports a growing list of business intelligence integrations — Hex, Metabase, DBeaver, and PowerBI among them — letting teams that already have BI infrastructure pull Dune query results into familiar environments.

Solana Coverage

Dune indexes the full Solana blockchain and exposes it through seven primary data table categories: account activity (pre/post-balance changes for every account touched in a transaction), blocks (slot-level data including leader identity, rewards, and timing), IDL tables (human-readable decoded program data), instruction calls (program instructions with arguments and inner calls), rewards (validator and staker distributions), transactions (complete records with signatures, fees, and execution status), and vote transactions (validator consensus votes).

Because Solana's architecture differs fundamentally from EVM chains — programs, accounts, and instructions replace contracts, addresses, and function calls — Dune maintains a dedicated Solana data model rather than forcing Solana data into EVM conventions. For most analytical workflows, decoded IDL tables provide the fastest path to insights; raw tables are available when deeper inspection is needed. The Spellbook repository includes a dedicated Solana sub-project with community-maintained models covering DEX activity and other high-level Solana concepts.

Real-time latency is tight: block headers and transaction signatures update in under a minute, making Dune's Solana data useful for near-live monitoring as well as historical analysis.

Supported Asset Classes

Beyond chain-level data, Dune maintains curated datasets for major asset classes across its supported chains. These include stablecoin datasets tracking issuance, circulation, and transfer patterns; tokenized real-world asset (RWA) data; prediction market feeds covering Polymarket and Kalshi; ERC-20 token data across 21 EVM chains; and NFT market data. The platform serves over 1.5 million datasets in total.

Background and Funding

Dune was founded in Oslo, Norway in 2018 by Fredrik Haga and Mats Olsen, who began the project during their time together at a Norwegian media company. The platform started as an Ethereum-focused analytics tool and expanded incrementally to cover additional chains and data types as the multi-chain ecosystem matured.

In 2018, Binance Labs made an initial investment. The company subsequently raised a Series A before a $69.4 million Series B in February 2022 led by Coatue Management, with participation from Dragonfly Capital and Multicoin Capital. The Series B valued Dune at $1 billion, making it one of the first blockchain data infrastructure companies to reach unicorn status. Total funding stands at $79.4 million.

Fredrik Haga remains CEO. The company employs over 100 people and serves over 1,500 paying customers including hedge funds, asset managers, and major media outlets. Dune operates a freemium model: the core query and dashboard functionality is free; premium features including higher query concurrency, private queries, Datashare access, and commercial API usage are available through paid plans.

Ecosystem Role

Dune has become a de facto data layer for the broader crypto ecosystem. Protocol teams use it to monitor their own contracts and communicate activity to their communities. Researchers and journalists use its dashboards as primary sources. Traders and quant firms use Datashare and the API to feed on-chain signals into models. For Solana specifically, Dune dashboards tracking DEX volumes across Raydium, Orca, Meteora, and Phoenix, as well as validator reward distributions and token program activity, serve as widely-cited reference points for understanding network health and DeFi activity.

The combination of a free, community-accessible tier — where anyone can query and publish findings without setting up infrastructure — and enterprise-grade data delivery options positions Dune at the intersection of open data and institutional analytics in the Solana ecosystem and beyond.
