# Deploying an Indexer (Subgraph) on Moonriver with The Graph

> Step-by-step guide for deploying a subgraph on Moonriver using The Graph for efficient blockchain data indexing and querying.

Deploying a subgraph on Moonriver using Mobula’s infrastructure is a straightforward process. This guide will walk you through the steps to get your subgraph up and running on the Moonriver network.

### What you’ll need

* Basic knowledge of The Graph and subgraphs.
* Your subgraph project files
* The Graph CLI installed
* A Mobula API key (for authentication)

### Walkthrough

<Steps>
  <Step title="Prepare Your Subgraph">
    Ensure your subgraph is configured for Moonriver. Update your `subgraph.yaml` file to reference Moonriver-specific contracts and events. If you don’t have a subgraph, you can clone the Uniswap V2 (Solarbeam) subgraph template and modify it for Moonriver:

    ```bash theme={null}
    git clone https://github.com/MobulaFi/univ2-subgraph-moonriver
    ```
  </Step>

  <Step title="Install Dependencies">
    Make sure you have The Graph CLI installed:

    ```bash theme={null}
    npm install -g @graphprotocol/graph-cli
    ```
  </Step>

  <Step title="Build Your Subgraph">
    Compile your subgraph before deployment:

    ```bash theme={null}
    graph codegen && graph build
    ```
  </Step>

  <Step title="Create the Subgraph">
    Use the following command to deploy your subgraph:

    ```bash theme={null}
    graph create --node https://subgraph.mobula.io:8020
    ```
  </Step>

  <Step title="Deploy to Mobula's Moonriver Node">
    Use the following command to deploy your subgraph:

    ```bash theme={null}
    graph deploy --node https://subgraph.mobula.io:8020 --ipfs https://subgraph.mobula.io:5001 --network moonriver
    ```
  </Step>

  <Step title="Authenticate">
    When prompted, provide your Mobula API key for authentication. Refer to the [authentication section](https://docs.mobula.io/indexing-stream/authentification) for more details on obtaining and using your API key.
  </Step>

  <Step title="Monitor Deployment">
    After deployment, you’ll receive a URL to monitor your subgraph’s indexing progress and status.
  </Step>
</Steps>

### Best Practices

* Regularly update your subgraph to ensure compatibility with the latest Moonriver network changes.
* Test your subgraph thoroughly on a testnet before deploying to mainnet.
* Monitor your subgraph’s performance and optimize queries for efficiency.

### Troubleshooting

If you encounter issues during deployment:

* Double-check your `subgraph.yaml` configuration.
* Ensure you’re using the correct network name and Mobula node URLs.
* Verify your API key is valid and has the necessary permissions.
