What is a Subgraph?

Subgraphs are an open-source tool for building custom GraphQL APIs with blockchain data.

How it works

1. Write your subgraph code.
2. Deploy to Alchemy Subgraphs.
3. Query live blockchain data through your GraphQL API.

Why use a subgraph?

• Ship in days, not weeks - Spend up to 50% less time on data indexing and dealing with forks / reorgs.
• Simplify your infrastructure - Save hours every week on infra maintenance or downtime.
