How to SEI it with SubQuery?

SubQuery is a fast & flexible blockchain indexing toolkit that powers hundreds of teams on blockchain networks such as Ethereum, Polkadot, Cosmos, Algorand and Avalanche. We also power NEAR and Aurora, and a number of Layer 2 chains such as Polygon, Arbitrum and Optimism.

Nothing much to say, but it’s very easy to do it with SubQuery. To do what? To create a SubQuery project indexing blockchain data within the SEI Network of course! Indexing the SEI Network allows developers to create a customised back end API to power their wondering and amazing front end dApps.

It takes about 3 minutes to get the SEI basic starter project up and running in a Docker environment. It is literally three lines of code.

subql init (to initialise the project and go through the step by step guide)
yarn install (install the dependencies)
yarn dev (to build & run the project in docker)

Once this is done and confirmed working, the next step is to follow our step by step quick start guide that indexed all ETH-USD exchange rates provided to Levana’s Sei DEX protocol by the Pyth price oracle. The quick start should take about 10–15 minutes and walked you through the various components of a SubQuery project.

At a high level, these are the steps are required:

1. Update Your GraphQL Schema File
2. Update Your Manifest File
3. Add a Mapping Function
4. Build Your Project
5. Run Your Project Locally with Docker

A sample query and the expected query result is also provided for reference.
