Dune (formerly Dune Analytics) is the most powerful community-driven on-chain data visualization platform in the cryptocurrency space. It allows users to directly query raw data from major blockchains such as Ethereum and Solana using SQL code, and transform it into intuitive charts and dashboards. For users who don't know how to code, Dune's core value lies in its vast community — you can directly view and freely use ready-made charts created by top analysts, such as NFT market share, DEX trading volume share, or user retention rates for specific projects. It is an essential tool for gaining insights into on-chain micro data and macro trends.
