# Welcome

> Dune is a web-based platform that allows you to query public blockchain data and aggregate it into beautiful dashboards.

Blockchains are open and transparent, but each chain is unique—making it difficult to understand, ingest, and aggregate data. Dune gives you the tools to analyze cross-chain data for different tokens, wallets, and protocols. You can also easily share your work with the community, export and integrate data into your own applications, and more.

### Why Dune?

Dune—along with our massive community of users and experts—provides powerful tools and analysis of all onchain data. You can find a [dashboard](https://dune.com/browse/dashboards?q=dex\&order=favorites\&time_range=all) for pretty much anything web3-related, including for EVMs like Ethereum, Polygon, Goerli, and Optimism—and non-EVM chains like Solana and Bitcoin.
