In this tutorial, you'll learn how to initialize a Solana-based Substreams project within the Dev Container.
Open the and follow the on-screen steps to initialize your project.
Running substreams init will give you the option to choose between two Solana project options. Select the one that best fits your requirements:
sol-minimal: Creates a simple Substreams that extracts raw Solana block data and generates corresponding Rust code. This path will start you with the full raw block, you can navigate to the substreams.yaml (the manifest) to modify the input.
sol-transactions: Creates a Substreams that filters Solana transactions based on one or more Program IDs and/or Account IDs, using the cached .
sol-anchor-beta: Given an Anchor IDL, create a Substreams that decodes instructions and events. If an IDL isn’t available using the idl subcommand within the , you’ll need to provide it yourself.
The modules within Solana Common exclude voting transactions, to benefit from a 75% reduction in data processing size and costs, delay your stream by over 1000 blocks from head. This can be done using the function in Rust.
Run substreams auth to create your and generate an authentication token (JWT), then pass this token back as input.
Now you can freely use the substreams gui to visualize and iterate on your extracted data.
Run substreams codegen subgraph to initialize the sink, producing the necessary files and function definitions.
Run substreams codegen sql and choose from either ClickHouse or Postgres to initialize the sink, producing the necessary files.
Run substreams-sink-sql to sink the data into your selected SQL DB.
You may find these additional resources helpful for developing your first Solana application.
Within the generated directories, modify your Substreams modules to include additional filters, aggregations, and transformations, then update the manifest accordingly. To learn more about this, visit the Within the generated directories, modify your Substreams modules to include additional filters, aggregations, and transformations, then update the manifest accordingly.

To make your Substreams queryable (as opposed to ), you can automatically generate a Subgraph (known as a or SQL-DB sink.
Create your within the mappings.ts and associated entities within the schema.graphql.
Build and deploy locally or to by running deploy-studio.
Run substreams build build the sink.
