# Coverage

> The chains and protocols Alterscope covers today — and the live endpoints that always tell you the current truth.

This page lists the chains and protocols Alterscope covers. It is a snapshot for orientation; to decide whether a **specific market** is covered right now, route the question to `GET /v2/data-manifest`, which reports completeness per row for the exact asset you care about:

* `GET /v2/data-manifest` — how *complete* the data is per protocol, right now. This is the endpoint to query for per-market coverage decisions.
* `GET /v2/assets` — the asset registry, with the chains each asset lives on.
* `GET /v2/protocols` — the protocol registry. Note that this registry does **not** yet list every indexed protocol (Euler V2, Blend, and SDEX, for example, have live connectors but no registry row), so a `/v2/protocols` lookup can false-negative. Don't use it as the authoritative coverage answer — use the data manifest.

Coverage depth varies by protocol, and we say so explicitly below — see [Coverage & gaps](/trust/data/coverage-and-gaps) for how to read it.

## Chains

| Chain        | Environment           | What's indexed                                                                                                                           |
| ------------ | --------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- |
| **Ethereum** | EVM mainnet           | Lending markets, vaults, oracle feeds with block-level history (via an [archive node](/trust/data/provenance)), and the knowledge graph. |
| **Stellar**  | Soroban + Stellar DEX | Blend lending pools, and SDEX orderbook + AMM liquidity metrics.                                                                         |

The asset and protocol registries are multi-chain by design, so an asset can carry addresses on more than one chain. The two environments above are where data is actively indexed today.

## Protocols

Coverage comes in depths. The deepest tier carries per-market data, oracle classification, and governance indexing; the next carries protocol-level metadata and risk factors. We mark which is which rather than implying uniform depth.

| Protocol                     | Chain            | Coverage depth                                                                                                                          |
| ---------------------------- | ---------------- | --------------------------------------------------------------------------------------------------------------------------------------- |
| **Morpho Blue**              | Ethereum         | Deepest — per-market data, MetaMorpho vault governance timeline, and [oracle classification](/trust/methodology/oracle-classification). |
| **Aave V3**                  | Ethereum         | Protocol metadata + risk factors.                                                                                                       |
| **Compound V3**              | Ethereum         | Protocol metadata + risk factors.                                                                                                       |
| **Euler V2**                 | Ethereum         | Protocol metadata + risk factors.                                                                                                       |
| **Pendle**                   | Ethereum         | Protocol metadata + risk factors.                                                                                                       |
| **Blend**                    | Stellar          | Lending pool metrics.                                                                                                                   |
| **Stellar DEX (SDEX / AMM)** | Stellar          | Orderbook depth, spread, and AMM pool liquidity metrics.                                                                                |
| **Hyperliquid**              | Hyperliquid (L1) | Perps venue metadata + risk factors.                                                                                                    |

<Note>
  This table is a documented baseline, not the live source of truth. If you are deciding whether a specific market is covered, query the [data manifest](/trust/data/coverage-and-gaps) (`GET /v2/data-manifest`) — it answers for the exact asset you care about, with completeness attached. The `GET /v2/protocols` registry is a complementary lens, but it does not yet list every indexed protocol (Euler V2, Blend, and SDEX have live connectors without a registry row), so don't rely on it alone to rule a market out.
</Note>

## Honest framing

* **Depth is not uniform.** A protocol appearing here means it is connected; it does not mean every market within it carries every signal. The [data manifest](/trust/data/coverage-and-gaps) reports completeness per row.
* **Coverage is expanding.** New connectors and chains are added over time. For the current per-market answer, query the [data manifest](/trust/data/coverage-and-gaps) (`GET /v2/data-manifest`) rather than this page — and note that `/v2/protocols` does not yet list every indexed protocol (e.g. Euler V2, Blend, SDEX).
* **Gaps are surfaced, not hidden.** Where a model or feed doesn't yet cover something, the response says so via its [freshness and quality](/trust/data/freshness-and-quality) metadata rather than guessing.
