# Substreams

Repo contains all substreams build by airstack.

# Steps to run the substream with substream cli

## Prerequisite

- [Install the substreams CLI](https://substreams.streamingfast.io/getting-started/installing-the-cli

)

- [Setup development env](https://substreams.streamingfast.io/developers-guide/installation-requirements)

- You will need firehose node to run substream, or you can use firehose node provided by streaming fast team for development. [Get a token to access firehose node](https://substreams.streamingfast.io/reference-and-specs/authentication). 

## Run a substream

1. Generate rust code with protogen

```

substreams protogen ./substreams.yaml --exclude-paths="sf/ethereum,sf/substreams,google"

```

2. Add target  wasm32-unknown-unknown

```

rustup target add wasm32-unknown-unknown

```

3. Build the project and install the rust dependencies

```

cargo build --target wasm32-unknown-unknown --release

```

If you face any authentication error on downloading dependencies, add below code to your ~/.gitconfig by using `code . ~/.gitconfig`

```

[url "https://github.com/rust-lang/crates.io-index"]

	insteadOf = https://github.com/rust-lang/crates.io-index

```

4. Run the substream. Make sure to change module name & block number based on substream.

```

substreams run -e mainnet.eth.streamingfast.io:443 \

   substreams.yaml \

   map_transfers \

   --start-block 10000000 \

   --stop-block 20000000

```
