Deploying a subgraph on Scroll with Mobula’s infrastructure is a simple process. This guide will take you through the steps to get your subgraph running on the Scroll network.

​
What you’ll need

  • Fundamental understanding of The Graph and subgraphs.
  • Your subgraph project files ready.
  • The Graph CLI installed.
  • A Mobula API key (for authentication).

​
Walkthrough

1

Prepare Your Subgraph

Make sure your subgraph is configured for Scroll. Update your subgraph.yaml file to point to Scroll-specific contracts and events. If you don’t have a subgraph, you can clone the Uniswap V2 (SushiSwap) subgraph template and customize it for Scroll:

git clone https://github.com/MobulaFi/univ2-subgraph-scroll
2

Install Dependencies

Make sure you have The Graph CLI installed:

npm install -g @graphprotocol/graph-cli
3

Build Your Subgraph

Compile your subgraph before deployment:

graph codegen && graph build
4

Create the Subgraph

Use the following command to deploy your subgraph:

graph create --node https://subgraph.mobula.io:8020
5

Deploy to Mobula's Scroll Node

Use the following command to deploy your subgraph:

graph deploy --node https://subgraph.mobula.io:8020 --ipfs https://subgraph.mobula.io:5001 --network scroll
6

Authenticate

When asked, enter your Mobula API key for authentication. For further details on acquiring and using your API key, refer to the authentication section.

7

Monitor Deployment

Following deployment, you’ll be provided with a URL to track your subgraph’s indexing progress and status.

​
Best Practices

  • Keep your subgraph regularly updated to ensure it remains compatible with the latest Scroll network changes.
  • Thoroughly test your subgraph on a testnet before deploying to the mainnet.
  • Continuously monitor its performance and optimize queries for greater efficiency.

​
Troubleshooting

If you encounter issues during deployment:

  • Review your subgraph.yaml configuration.
  • Confirm that you’re using the correct network name and Mobula node URLs.
  • Ensure your API key is valid and has the required permissions.
