Uniswap V3 Subgraph

Subgraph Studio Deployment

To deploy a Uni V3 Subgraph to the Subgraph Studio, you need to follow these steps:

1. Create a new subgraph in the Subgraph Studio. Documentation can be found here.
2. Then, you need to change the following fields in the subgraph.yaml file to deploy a subgraph with the correct configuration:
   1. network - the network where the subgraph will be deployed (e.g., mainnet, sepolia, polygon, etc.). This must be changed in two places.
   2. address - the address of the Uniswap V3 Factory contract deployed on the desired network mentioned in the previous step.
   3. startBlock - the block number from which the subgraph will start indexing. It is recommended to set it to the block number when the Uniswap V3 Factory contract was deployed.
3. Refer to this documentation to deploy the subgraph to the Subgraph Studio.
   1. Note that graph commands can be run from the root of the repository as follows:

      npx graph init --studio <SUBGRAPH_SLUG>
      graph auth --studio <DEPLOY KEY>

4. After all the steps are done, you can deploy the subgraph to the Subgraph Studio by running the following command:

   npx graph deploy --studio <SUBGRAPH_SLUG>

5. The subgraph will be deployed to the Subgraph Studio, and you can find it in the Subgraph Studio.
6. To query the subgraph, you can use the following development query endpoint, e.g.:

   https://api.studio.thegraph.com/query/<uuid>/<SUBGRAPH_SLUG>/version/latest
   

Running Unit Tests
