# WeETHOracle

Ethereum uses two different V2 source families for weETH routes. They share the [capped base API](/technical-reference/reference-oracle/correlated-token-oracles/correlated-token-oracle.md) but not the same derived constructor or exchange-rate source.

| Route           | Address                                      | Derived source  | Checked state at block `25845949`                                                            |
| --------------- | -------------------------------------------- | --------------- | -------------------------------------------------------------------------------------------- |
| equivalence     | `0xaB663D4a701229DFF407Eb4B45007921029072e9` | `WeETHOracle`   | interval `2,592,000`, growth/second `1,680,618,975`, gap `4,704,509,580,349,536`, not capped |
| non-equivalence | `0x92469958A4C00101F9F290cc3AC32959Af497EAf` | `OneJumpOracle` | cap disabled: interval, growth, and gap all zero                                             |

The [`WeETHOracle` v2.16.0 source](https://github.com/VenusProtocol/oracle/blob/v2.16.0/contracts/oracles/WeETHOracle.sol) uses:

```solidity
constructor(
    address liquidityPool,
    address weETH,
    address eETH,
    address resilientOracle,
    uint256 annualGrowthRate,
    uint256 snapshotInterval,
    uint256 initialSnapshotMaxExchangeRate,
    uint256 initialSnapshotTimestamp,
    address accessControlManager,
    uint256 snapshotGap
)
```

It obtains the underlying amount through `liquidityPool.amountForShare(1e18)`. The non-equivalence instance instead uses the ten-argument [`OneJumpOracle`](/technical-reference/reference-oracle/correlated-token-oracles/one-jump-oracle.md) constructor with an immutable intermediate oracle.

The equivalence implementation exposes its immutable dependency through `LIQUIDITY_POOL()`.

Select the instance from the live ResilientOracle token config. “Equivalence” is deployment configuration, not a boolean getter shared by both addresses.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs-v4.venus.io/technical-reference/reference-oracle/correlated-token-oracles/we-eth-oracle.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
