### yDAIv2

None ✅

### yUSDCv2

None ✅

### yUSDTv2

* set\_new\_APR ✅

```
No interaction with funds.

APR used for stateless recommend() function. Can be used to change the recommended provider. The owner could replace the existing contract to a controlled contract that could suggest a specific lending provider.
```

* set\_new\_COMPOUND ⚠️

```
Could access funds via malicious lending contract.

Sets the downstream address for Compound. The owner could replicate the compound mint() function call and force the APR change (with the vector mentioned in set_new_APR) and withdraw funds.

This method is implemented to allow adding Compound if they support the underlying token.
```

* set\_new\_DTOKEN ✅

```
No interaction with funds.

Can only update the ID at dydx, no way to influence any other action.

This method is implemented to allow adding dYdX if they support the underlying token.
```

* set\_new\_FULCRUM ⚠️

```
As per set_new_COMPOUND
```

### yTUSDv2

* set\_new\_APR ✅
* set\_new\_COMPOUND ⚠️

# 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 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://andrecronje.gitbook.io/yearn-finance/developers/misc-resources/adminpolicy.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.
