The Graph Subgraph Integration for Scaffold-ETH 2

Prerequisites

Check if ./packages/nextjs/scaffold.config.ts exists directly in the current working directory (do not search subdirectories). If it doesn't exist, this is not a Scaffold-ETH 2 project. Follow the instructions at https://docs.scaffoldeth.io/SKILL.md to scaffold it first. If it exists, continue directly with building.

Overview

The Graph is a decentralized indexing protocol for querying blockchain data via GraphQL. A subgraph defines which contract events to index, how to transform them, and exposes the indexed data through a GraphQL API. This skill adds a subgraph workspace to SE-2, with a local Graph Node (via Docker) for development and deployment to Subgraph Studio for production.

For The Graph's full API reference, see the official docs. This skill focuses on the SE-2 integration — the workspace structure, the ABI copy bridge, and local development workflow.
