The Graph

Overview

Getting historical data on a smart contract can be frustrating when building a dapp. The Graph provides an easy way to query smart contract data through APIs known as subgraphs. The Graph’s infrastructure relies on a decentralized network of indexers, enabling your dapp to become truly decentralized.

Features

• Decentralized Indexing: Enables indexing blockchain data through multiple indexers, thus eliminating any single point of failure
• GraphQL Queries: Provides a powerful GraphQL interface for querying indexed data, making data retrieval super simple.
• Customizable & Reusable: Define your own logic for transforming & storing blockchain data. Reuse subgraphs published by other developers.
• Data Aggregation: Aggregates data from multiple blockchain sources, offering a unified view for easier access and analysis.
• Scalability: Designed to handle large volumes of data and scale with the needs of growing dApps and data requirements.

Getting Started

Building a subgraph only takes a few minutes. It primarily consists of the following steps:

1. Initialize your subgraph project
2. Deploy & Publish
3. Query from your dapp
