Yearn Vaults V2 Subgraph

This is the official subgraph for the Vault V2 - Yearn Protocol.

The subgraph is being updated and fixed constantly.

Get Started

To get started, you need to install the dependencies:

  • Using Yarn: yarn install
  • Using NPM: npm install

To run tests;

  1. Make sure your installed version of graph is newer than 0.22.0 using graph --version
  2. If you don't have Postgres installed, install it;
  3. Run yarn prepare:mainnet or yarn prepare:fantom to prepare subgraph.yaml.
  4. Run yarn test. Graph CLI should download and install a binary for the testing framework, Matchstick. Once the testing framework is set up, the tests will be run. If this does not work, you may need to compile Matchstick locally and run tests using $matchstick_build_dir/matchstick instead.

Network Configuration

Once the smart contracts are deployed on a testnet or mainnet, the JSON files located at folder config must be updated.

The final subgraph.yaml file is used to deploy on the network.


Each network has a JSON file in the ./config folder. When a deploy process is executed (using a script defined in the package.json), it creates the final subgraph.yaml, and deploy it to the The Graph node.


At this moment, the scripts available are:

  • yarn deploy:fantom: build the subgraph.yaml file, and deploy it on the Fantom network.
  • yarn deploy:mainnet: build the subgraph.yaml file, and deploy it on the mainnet Ethereum network.
  • yarn deploy:arbitrum: build the subgraph.yaml file, and deploy it on the Arbitrum network.

We don't support Ethereum testnets at the moment.
