# Auxiliary services

## FVM

Other new opportunities are emerging since the launch of FVM (Filecoin Virtual Machine) in March 2023. The FVM allows smart contracts to be executed on the Filecoin blockchain. The FVM is Ethereum-compatible (also called the FEVM) and allows for entire new use cases to be developed in the Filecoin ecosystem. Think of on-chain FIL lending as an example, but the opportunities are countless.

## Storage tiering

Another potential service to offer is storage tiers with various performance profiles. For example, storage providers can offer hot/online storage by keeping an additional copy of the unsealed data available for immediate retrieval, as well as the sealed that has been stored on the Filecoin Network.

## 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.filecoin.io/provide-storage/filecoin-deals/auxiliary-services.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.
