Creating a subgraph on Linea using Mobula’s infrastructure is a straightforward task. This guide will help you set up and deploy your subgraph on the Linea network efficiently.

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

Set up your subgraph for Linea. Update your subgraph.yaml file to reference Linea-specific contracts and events. If you don’t have a subgraph, you can clone the Uniswap V2 (PancakeSwap) subgraph template and adapt it for Linea:

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

Install Dependencies

Make sure you have The Graph CLI installed:

npm install -g @graphprotocol/graph-cli
3

Install Mobula CLI

Install our CLI tool using npm:

npm i mobula-cli
4

Setup API Key

Configure your API key with the CLI. You can get your API key from the Dashboard. Please refer to the authentication section for detailed steps on obtaining your API key.

mob apikey set
5

Build Your Subgraph

Compile your subgraph before deployment:

graph codegen && graph build
6

Deploy your subgraph

Deploy your subgraph using the Mobula CLI:

mob deploy -n subgraphName
7

Monitor Deployment

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

Best Practices

  • Keep your subgraph up to date to ensure it aligns with the latest Linea network changes.
  • Conduct comprehensive testing on a testnet before mainnet deployment.
  • Continuously monitor performance and fine-tune queries for maximum efficiency.

Troubleshooting

If you encounter deployment problems:

  • Double-check your subgraph.yaml configuration.
  • Verify that the network name and Mobula node URLs are correct.
  • Make sure your API key is valid and properly authorized.
