Data Indexers

Data indexing is essential for enabling your dApp to efficiently read blockchain data. While blockchains are designed for seamless data writing, reading data can be challenging—especially when dealing with large volumes or requiring data transformation.

Below is a list of indexing providers that can help you index data for your smart contract on Optimism.

The Graph

The Graph (opens in a new tab) is an indexing protocol that provides an easy way to query blockchain data through APIs known as subgraphs.

With The Graph, you can benefit from:

• Decentralized Indexing: Improves redundancy and query speed. Lets you eliminate any single point of failure.
• GraphQL Queries: Provides a powerful GraphQL interface for querying indexed data, making data retrieval super simple.
• Customization: Define your own logic for transforming & storing blockchain data. Reuse subgraphs published by other developers on The Graph Network.
