# afETH Functionality

afETH is a hybrid LST built of 70% sfrxETH and 30% vlCVX - Visualized below.

Users mint afETH - User deposits are automatically split into 70% sfrxETH and 30% vlCVX. Both assets are held in the afETH contract.

sfrxETH automatically accrues rewards via a price redemption mechanism. CVX is locked in the Convex Vote Locker contract and the voting power is delegated to Votium. On a bi-weekly basis, yield is harvested from Votium, converted into ETH, and entered into The Yield Smoother.

#### The Yield Smoother

Similar to Yearn's vaults, new ETH rewards are locked up and only gradually accrue to the total value of the vault over time. This is to prevent large discrete jumps in the ETH/afETH price such that a searcher or other MEV extractor could sandwich reward distributions to capture most of their value.

#### Fees

There are no fees. Really.

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.asymmetry.finance/afeth-asymmetry-finance-eth/afeth-functionality.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.
