About the Graph

The Graph is the indexing and query layer of web3. The Graph Network’s self service experience for developers launched in July 2021. Developers build and publish open APIs, called subgraphs, that applications can query using GraphQL. The Graph supports indexing data from multiple different networks including Ethereum, NEAR, Arbitrium, Optimism, Polygon, Avalanche, Celo, Fantom, Moonbeam, IPFS, and PoA with more networks coming soon. To date, tens-of-thousands of subgraphs have been deployed on the hosted service, and now subgraphs can be deployed directly on the network. Over 28,000 developers have built subgraphs for applications such as Uniswap, Synthetix, KnownOrigin, Art Blocks, Balancer, Livepeer, DAOstack, Audius, Decentraland, and many others.

If you are a developer building an application or web3 application, you can use subgraphs for indexing and querying data from blockchains. The Graph allows applications to efficiently and performantly present data in a UI and allows other developers to use your subgraph too! You can deploy a subgraph to the network using the newly launched Subgraph Studio or query existing subgraphs that are in the Graph Explorer. The Graph would love to welcome you to be Indexers, Curators and/or Delegators on The Graph’s mainnet. Join The Graph community by introducing yourself in The Graph Discord for technical discussions, join The Graph’s Telegram chat, and follow The Graph on Twitter, LinkedIn, Instagram, Facebook, Reddit, and Medium! The Graph’s developers and members of the community are always eager to chat with you, and The Graph ecosystem has a growing community of developers who support each other.

The Graph Foundation oversees The Graph Network. The Graph Foundation is overseen by the Technical Council. Edge & Node, StreamingFast, Messari, Semiotic  and The Guild are five of the many organizations within The Graph ecosystem.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
