Develop Your First Substreams
These tutorials demonstrate how to quickly index on-chain data for your application across various blockchains using the Substreams Dev Container. These tutorials are beginner friendly and are intended for developing either a programmable stream (Substreams) or programmable API (Substreams-powered Subgraphs).
Substreams data streams are available on the chains listed here. To support Substreams a Firehose endpoint must be available.
If your blockchain is not supported, please ask in Discord. Then, consult the relevant ecosystem guide to get started using Substreams real-time data streams:
