Alchemy

Alchemy Subgraphs is a blockchain indexing platform with drop-in support for hosted subgraphs.

Subgraphs are an open-source tool for building custom GraphQL APIs from on-chain data.

Identify on-chain events you want to index, write AssemblyScript handlers to transform them into your preferred format, and let the subgraph automatically ingest new events for you immediately as they happen.

Why subgraphs?

Developing an in-house indexing system is time-consuming, expensive, and requires ongoing expertise in data pipelines, devOps, and more.

Subgraphs handle the intricacies of data ingestion, decoding, and database management for you. Just define the data format you want and query live data through a GraphQL API.

Why Alchemy Subgraphs?

• Simple and reliable. We make payment easy (just a credit card, no staking tokens) and have guaranteed uptime.
• Developer tooling. Access developer tools like error logs, subgraph versioning, indexing performance metrics, and more.
• Easy migration. If you have existing subgraphs, it takes just 5 minutes to switch over using the familiar command line tools.
