# BNBxOracle

[`BNBxOracle`](https://github.com/VenusProtocol/oracle/blob/v2.16.0/contracts/oracles/BNBxOracle.sol) calls the immutable Stader StakeManager to convert one BNBx into BNB, then applies the ResilientOracle BNB price. It inherits the [capped V2 base](/technical-reference/reference-oracle/correlated-token-oracles/correlated-token-oracle.md).

```solidity
constructor(
    address stakeManager,
    address bnbx,
    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 `0xC2E2b6f9CdE2BFA5Ba5fda2Dd113CAcD781bdb31`. At block `118367342`, its snapshot interval was `2,592,000` seconds, its growth rate was `2,387,747,336` per second, its gap was `6,956,741,073,522,234`, and `isCapped()` returned false.

`STAKE_MANAGER()` exposes the immutable Stader dependency, and `NATIVE_TOKEN_ADDR()` exposes the BNB pricing sentinel. These values, token addresses, and cap configuration are instance-specific; do not reuse them from another BNB-correlated oracle.

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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
