Deploying an Indexer (Subgraph) on Hedera with The Graph
Guide to deploying a subgraph on Hedera using The Graph for efficient blockchain data indexing and querying.
Deploying a subgraph on Hedera with Mobula’s infrastructure is a simple process. This guide will take you through the steps to get your subgraph running on the Hedera network.
What you’ll need
- Fundamental understanding of The Graph and subgraphs.
- Your subgraph project files ready.
- The Graph CLI installed
- A Mobula API key (for authentication)
Walkthrough
Prepare Your Subgraph
Make sure your subgraph is configured for Hedera. Update your subgraph.yaml file to point to Hedera’s specific contracts and events. If you don’t have a subgraph, you can clone the Uniswap V2 (SaucerSwap) subgraph template and customize it for Hedera:
Install Dependencies
Make sure you have The Graph CLI installed:
Install Mobula CLI
Install our CLI tool using npm:
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.
Build Your Subgraph
Compile your subgraph before deployment:
Deploy your subgraph
Deploy your subgraph using the Mobula CLI:
Monitor Deployment
After deployment, you’ll receive a URL to monitor your subgraph’s indexing progress and status.
Best Practices
- Keep your subgraph regularly updated to ensure it remains compatible with the latest Hedera network changes.
- Thoroughly test your subgraph on a testnet before deploying to the mainnet.
- Continuously monitor its performance and optimize queries for greater efficiency.
Troubleshooting
If you encounter issues during deployment:
- Review your
subgraph.yamlconfiguration. - Confirm that you’re using the correct network name and Mobula node URLs.
- Ensure your API key is valid and has the required permissions.
