# Subgraphs

{% hint style="warning" %}
These subgraphs are for **Fuul Protocol v1**. If you are using v2, refer to the relevant sections in the developer documentation.
{% endhint %}

Every token reward program has an onchain record on the Fuul Protocol v1 contracts. This information can be retrieved from any indexer, but using our aggregated subgraphs makes it much easier.

Fuul subgraphs are mainly used for:

* [Getting onchain rewards](/developer-guide/getting-individual-rewards.md)
* [Getting onchain claimable rewards](/developer-guide/claiming-onchain-rewards.md)

### Github Repo

The subgraph code is hosted on this GitHub repo:
