# InterestRateModelLens

The former page described this function:

```solidity
function getNextInterestRates(
    uint256 cash,
    uint256 borrows,
    uint256 reserves,
    uint256 reserveFactorMantissa,
    uint256 badDebt,
    InterestRateModel interestRateModel
) external view returns (uint256 borrowRate, uint256 supplyRate)
```

No canonical source file, deployed address, supported network, or current consumer for `InterestRateModelLens` has been identified in the stable Venus repositories or deployment registries.

{% hint style="danger" %}
Do not assume this contract is deployed or supported. Simulate rates by calling the exact model selected by the target market, after resolving any `CheckpointView` wrapper. See [BNB Core Interest Rate Models](/technical-reference/reference-core-pool/interestratemodels.md).
{% endhint %}

This page is retained only to prevent old links from silently implying that the unverified ABI is current. It can be archived after integrations and ownership are conclusively ruled out.

## 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-core-pool/interestratemodels/interestratemodellens.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.
