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

Ensure your subgraph is configured for Ethereum. Update your subgraph.yaml file to reference Ethereum-specific contracts and events. If you don’t have a subgraph, you can clone the Uniswap V2 subgraph template and modify it for Ethereum:

git clone https://github.com/MobulaFi/univ2-subgraph-ethereum
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 Ethereum Node

Use the following command to deploy your subgraph:

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

Authenticate

When prompted, provide your Mobula API key for authentication. Refer to the authentication section for more details 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

  • Regularly update your subgraph to ensure compatibility with the latest Ethereum network changes.
  • Test your subgraph thoroughly on a testnet before deploying to mainnet.
  • Monitor your subgraph’s performance and optimize queries for efficiency.

​
Troubleshooting

If you encounter issues during deployment:

  • Double-check your subgraph.yaml configuration.
  • Ensure you’re using the correct network name and Mobula node URLs.
  • Verify your API key is valid and has the necessary permissions.
