# WBETHOracle

[`WBETHOracle`](https://github.com/VenusProtocol/oracle/blob/v2.16.0/contracts/oracles/WBETHOracle.sol) obtains BETH per WBETH from `WBETH.exchangeRate()`, then uses the configured ETH price from the ResilientOracle. It inherits the [capped V2 base](/technical-reference/reference-oracle/correlated-token-oracles/correlated-token-oracle.md).

```solidity
constructor(
    address wbeth,
    address eth,
    address resilientOracle,
    uint256 annualGrowthRate,
    uint256 snapshotInterval,
    uint256 initialSnapshotMaxExchangeRate,
    uint256 initialSnapshotTimestamp,
    address accessControlManager,
    uint256 snapshotGap
)
```

The BNB mainnet v2.16.0 artifact is the non-proxy contract `0x49938fc72262c126eb5D4BdF6430C55189AEB2BA`. At block `118367342`, its snapshot interval was `2,592,000` seconds, its growth rate was `1,471,334,348` per second, its gap was `4,215,128,607,557,400`, and `isCapped()` returned false.

BNB testnet deployment artifacts include an older proxy shape. Select ABI by address and environment rather than applying this mainnet V2 constructor globally.

# 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/wbeth-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.
