The Balancer Subgraph indexes data on the Balancer smart contracts with a GraphQL interface. It updates data in response to function calls and contract events to maintain data on the Vault, Pools, AssetManagers etc, to power front-end apps and integrations.
{% hint style="warning" %} Note that Balancer has not yet migrated to the new Subgraph Studio mainnet. Any Balancer subgraphs appearing there should not be considered "official" deployments. Use at your own risk! {% endhint %}
The schema of GraphQL elements available is defined in /schema.graphql
The data included in this subgraph data layer is the data that is most applicable to the front-end. It aims at the very least to keep track of all the resources in the Vault contract, and keep track of basic pool data.
{% hint style="info" %} For an in-depth explanation of how to query the Subgraph, check out the Balancer Subgraph article in Guides. {% endhint %}
