The Graph Prize: Build a Subgraph ($500)

[html5cat]

Build a Subgraph for your favourite contract

Hello ETH Berlin Hackers! Do you need to get data from the Ethereum blockchain for your web or mobile dApp? Do you like your APIs served via GraphQL endpoints? Build a subgraph for your favourite contract and win $500!

(if you want to build a dApp check out our main prize here)

Qualification Guidelines

Follow these steps to be eligible for our Bounty:

1. Join our Discord - This will be your first stop for engaging with the team. Post in the #hackathon channel and let us know what you’re working on. We’ll touch base to make sure you have a viable plan for using The Graph in your awesome project.
2. Get an API key or run Graph Node locally - We’re going to be running some Graph Nodes so you don’t have to waste time setting up the infrastructure. Once you post in the Discord channel, one of our team members will get in touch with an API key that you can use at the hackathon and up to 3 months afterwards.
3. Create a Subgraph - Use this example to see how to create a Subgraph. Your subgraph will ingest data from an Ethereum smart contract and make it available for querying over GraphQL.
4. Demo - Play with the API and showcase some of your favourite queries!

• Potential utility of the Subgraph for the community
• Completeness of the implementation, technical difficulty and code quality
