Signal21

Signal21 is the leading data and visualization platform for the Stacks blockchain. Data is sourced from the nodes into PostgreSQL database, preprocessed, and delivered to you through our many chart tools. Just in case you need more, this documentation will help you answer questions like :

• Is Activity on the Stacks blockchain increasing?

• Is the floor rising on your NFTs?

• Which NFT has the highest Volume?

• What is the TVL on the DeFi Platforms?

Signal21 is a collaborative effort by the Stacks community; many people helped build this website. This will be even more enforced with every query written. All dashboards are public, but creators are anonymous to the public for now. So feel free to make mistakes and learn.

An easy way to get started is to copy an existing dashboard query by clicking on the information icon on the top left of every dashboard chart, then paste it in our query editor and edit it depending on your needs. You can always find us on Twitter and ask for help; we were all beginners at one point.

Before we start, while querying the tables, you'll find many more columns than what is presented in this documentation. That is because we ideally want to provide the node data without significant changes and make it more user-friendly. We don't want to drastically change the data from what our nodes transmit, as it can still be helpful to a minority of advanced researchers. But even as a Blockchain Analyst, most of what you'll need will be in this documentation.
