Setting up a subgraph on zkSync with Mobula’s infrastructure is an easy process. This tutorial will guide you through each step to get your subgraph operational on the zkSync 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

Configure your subgraph for zkSync. Adjust your subgraph.yaml file to reference zkSync-specific contracts and events. If you don’t have a subgraph yet, you can clone the Uniswap V2 (zkSwap) subgraph template and tailor it for zkSync:
git clone https://github.com/MobulaFi/univ2-subgraph-zksync
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 zkSync Node

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

Authenticate

When requested, input your Mobula API key for authentication. Check the authentication section for detailed instructions on obtaining and using your API key.
7

Monitor Deployment

After deployment, you’ll receive a URL to monitor your subgraph’s indexing progress and status.

​
Best Practices

  • Ensure your subgraph is consistently updated to stay compatible with the latest zkSync network changes.
  • Perform thorough testing on a testnet before deploying to the mainnet.
  • Regularly monitor its performance and optimize queries for improved efficiency.

​
Troubleshooting

If you face issues during deployment:
  • Review your subgraph.yaml file carefully.
  • Ensure the network name and Mobula node URLs are correct.
  • Check that your API key is valid and has the appropriate permissions.
