Indexing Data on Solana

Solana is a high-throughput Layer 1 known for fast, low-cost transactions and a large DeFi, NFT, and payments ecosystem. The Graph can stream that onchain activity — program interactions, DEX swaps, token transfers and balances, and account updates — as real-time data with Substreams.

Solana is supported by The Graph with Substreams — a parallelized, real-time streaming engine for high-throughput use cases — via The Graph Market⁠ and Pinax Network⁠.

Indexing Solana with Substreams

Substreams is a parallelized, real-time streaming engine for extracting and transforming blockchain data. Where a Subgraph indexes into a hosted GraphQL API, Substreams lets you consume high-throughput data directly or via 10+ supported sinks. Solana is available through Substreams’ Solana block model, so modules have access to blocks, transactions, and instructions. Modules are written in Rust and composed into reusable packages.

Find an Existing Module on Substreams.dev

Before writing any code, check the Substreams Registry⁠ for a package that already does what you need. The registry hosts community- and team-built modules covering common onchain data that you can run as-is or compose into your own pipeline. Search for the protocol or data you want on Solana; if a module fits, you can consume its output directly or import it as a dependency in your own project.

Develop Your Own Substreams Module

If no existing module fits, you can build one. The Substreams Quick Start is the full walkthrough. In short:

1. Install the Substreams CLI and get a key at thegraph.market⁠ (no personal information required).
2. Scaffold a project with substreams init and choose the Solana path.
3. Write your extraction and transformation logic in Rust, then run substreams build.
4. Stream the output with substreams gui (or substreams run) to iterate, then publish your package to the Substreams Registry⁠ to reuse or share it.
