Retrieve The Graph Chain IDs

This process is useful to add a supported chain to the app, as we need to make sure that the chain is available on The Graph to provide a valid TOML quickstart config. GraphID type is automatically updated on pre-commit, so in most cases you don't need to worry about it.

In the case that the chain is not available on The Graph, we set its graph_id to null, so that the TOML config shows This chain is not supported by The Graph Network.

Steps to retrieve The Graph Chain IDs

OPTION A: Run npm run fetch-graph-ids in the project

1. Clone the repository
2. At the root of the project, run npm run fetch-graph-ids

OPTION B: CURL

1. Fetch The Graph Supported Chains
   • Option A: Install JQ and run cURL command curl -X POST -H "Content-Type: application/json" -d '{ "jsonrpc": "2.0", "method": "chain_list", "id": 1 }' https://api.studio.thegraph.com/deploy | jq
   • Option B: Use your favorite HTTP Client to retrieve it:

   {
      "url": "https://api.studio.thegraph.com/deploy",
      "headers": {
         "Content-Type": "application/json"
      },
      "body": {
          "jsonrpc": "2.0",
          "method": "chain_list",
          "id": 1
      }
   }

2. See if you can find a chain ID matching the chain you are adding to the app under "hostedService"
3. If you can't find any matching ID, the added chain will have graph_id: null, otherwise the chain ID
