Deploying a subgraph on Polygon zkEVM 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 zkEVM 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)
1

Prepare Your Subgraph

Make sure your subgraph is set up for Polygon zkEVM. Modify your subgraph.yaml file to reference zkEVM-specific contracts and events. If you don’t have a subgraph, you can clone the Uniswap V2 (QuickSwap) subgraph template and adjust it for Polygon zkEVM:

git clone https://github.com/MobulaFi/univ2-subgraph-polygonzkevm
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 http://subgraph.mobula.io:8020
5

Deploy to Mobula's Polygon zkEVM Node

Use the following command to deploy your subgraph:

graph deploy --node http://subgraph.mobula.io:8020 --ipfs http://subgraph.mobula.io:5001 --network polygonzkevm
6

Authenticate

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

7

Monitor Deployment

After deployment, 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 zkEVM 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.
  • Ensure your API key is valid and has the required permissions.
