# Subgraph

Chamber's subgraphs are The Graph Protocol deployments that index vault state, deposits, withdrawals, trades, and manager activity. They are the primary source for analytics, dashboards, leaderboards, and any UI that needs to list or filter vaults.

**Repo:** `dhedge-v2-subgraphs`

## When to use the subgraph

* **List or search vaults** — by manager, denomination asset, chain, performance.
* **Reconstruct vault history** — deposits, withdrawals, trades, fee events over time.
* **Power a leaderboard or directory** — see [leaderboard & ranking](/concepts/leaderboard-ranking.md).
* **Build portfolio views** — a depositor's positions across multiple vaults.

For live state (current NAV, open positions), call the contracts directly or use the [SDK](/build/sdk.md) — subgraphs lag the chain by a few blocks.

## Chain coverage

Separate subgraph deployments exist per chain:

* Polygon
* Optimism
* Arbitrum
* Base
* Plasma
* Ethereum
* HyperEVM

Each chain has its own GraphQL endpoint. There is no single cross-chain endpoint — aggregate on the client side.

**Endpoints:** Per-chain GraphQL URLs are maintained in the subgraph repo README.

## What gets indexed

Full schema is in the subgraph repo's `schema.graphql`. The schema evolves with contract upgrades — pin your integration to a specific subgraph version if you depend on exact field shapes.
