Subgraph Deployment

In some instances like a frontend you might need to deploy a subgraph, in the MACI repository you can find the configuration to deploy a subgraph on The Graph Network.

important

MACI subgraphs can be deployed in Alchemy and The Graph network, this guide focuses on deploying on The Graph.

Configuration

Head to the subgraph folder in the app folder.

cd apps/subgraph

Edit the network.json file in the config folder. Adding the network it was deployed, the MACI contract and the block where it was deployed.

{
  "network": "optimism-sepolia",
  "maciContractAddress": "0xD18Ca45b6cC1f409380731C40551BD66932046c3",
  "maciContractStartBlock": 11052407
}

note

See the supported networks of The Graph here.

Create a subgraph in the graph studio and name it maci-subgraph.

Deployment

The first thing you need to do is to copy the key in subgraph studio dashboard and run the following command to authenticate:

graph auth --studio {key}

Then run the following commands to build and deploy the subgraph:

pnpm run build && \
pnpm run deploy

important

The pnpm run deploy command uses maci-subgraph as the subgraph name by default, but if you named your subgraph differently (e.g. maci-graph, my-graph, etc.), please change the command to graph deploy --node https://api.studio.thegraph.com/deploy/ your_subgraph_name
