Deploying a subgraph on Polygon with Mobula’s infrastructure is a simple process. This guide will walk you through the steps to get your subgraph up and running on the Polygon 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

1

Prepare Your Subgraph

Make sure your subgraph is set up for Polygon. Modify your subgraph.yaml file to point to Polygon-specific contracts and events. If you don’t have a subgraph yet, you can clone the Uniswap V2 subgraph template and adjust it for Polygon:
git clone https://github.com/MobulaFi/univ2-subgraph-polygon
2

Install Dependencies

Ensure that The Graph CLI is installed:
npm install -g @graphprotocol/graph-cli
3

Build Your Subgraph

Compile your subgraph prior to 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 Polygon Node

Use the following command to deploy your subgraph:
graph deploy --node https://subgraph.mobula.io:8020 --ipfs https://subgraph.mobula.io:5001 --network polygon
6

Authenticate

When prompted, enter your Mobula API key for authentication. For more information on obtaining and using your API key, refer to the authentication section.
7

Monitor Deployment

Once deployment is complete, you’ll receive a URL to track your subgraph’s indexing progress and status.

​
Best Practices

  • Keep your subgraph regularly updated to maintain compatibility with the latest Polygon network changes.
  • Thoroughly test your subgraph on a testnet before deploying to the mainnet.
  • Continuously monitor your subgraph’s performance and optimize queries for better efficiency.

​
Troubleshooting

If you encounter issues during deployment:
  • Carefully review your subgraph.yaml configuration.
  • Confirm that you’re using the correct network name and Mobula node URLs.
  • Make sure your API key is valid and has the required permissions.
