# Tycho Substreams SDK Some shared functionality that is used to create tycho substream packages. ## Protobuf Models Protobuf models are manually synced from the `tycho-indexer` repository whenever they changed. To generate the rust structs run the following command from within the root directory: ```bash buf generate --template substreams/crates/tycho-substreams/buf.gen.yaml --output substreams/crates/tycho-substreams/ ```
