Lighter Rust Data Client Starter

This quickstart builds a minimal Rust LiveNode with the Lighter data client and the built-in DataTester actor. cargo run connects to Lighter testnet public streams.

Run

cargo run

Stop the node with Ctrl+C.

The quickstart uses public data only. Execution clients and live order submission need the credential variables documented in the Lighter integration guide.

Next steps

• Change INSTRUMENT_ID to another Lighter market such as ETH-PERP.LIGHTER.
• Enable subscribe_book_deltas(true) and manage_book(true) in DataTesterConfig for L2 MBP data.
• Add an execution client only after the data path is working.
