# Token Breakdown

Since the launch of the first iteration of the protocol, several tokens have been launched. Please find a breakdown below to help you navigate along them.

## Stablecoins

* fxUSD: Our flagship stablecoin, operating on v2. It is exclusively collateralized by Lido stETH and WBTC. While governance may introduce additional collateral types, they will always consist of the most liquid and secure assets in DeFi.
* fxSAVE: the ultimate DeFi savings account. This yield-bearing stablecoin harnesses the [Stability Pool](/fx-docs/f-x-protocol-mechanisms/stability-pool.md)'s yields.
* rUSD: A v1 stablecoin backed by Etherfi eETH and Renzo ezETH. Once staked, it not only earns restaking yields but also provides points!
* btcUSD: A v1 stablecoin collateralized by wBTC. Since wBTC is not yield-bearing, a small funding cost is charged to xToken holders and distributed to stable stakers.
* cvxUSD: A v1 stablecoin backed by aCVX, an auto-compounding staked CVX created by [Concentrator](https://concentrator.aladdin.club/).
* fETH: Our first-ever v1 stablecoin, designed differently. Instead of being pegged to the dollar, it maintains stability by capturing only 10% of ETH's volatility, with its xToken absorbing the rest.<br>

## Leveraged tokens (V1)

* xETH: a perpetual leveraged token providing up to 4x long exposure to ETH price movements, backed by Lido stETH exclusively.
* xstETH / xfrxETH: ETH leverage tokens offering up to 4.3x exposure. Respectively backed by Lido stETH and frxETH.
* xeETH / xezETH: ETH leverage tokens with up to 4.3x exposure. Respectively backed by Lido eETH and ezETH.
* xwBTC:\
  A Bitcoin leverage token offers up to 5.6x exposure, enabling traders to capitalize on market movements precisely.
* xCVX:\
  A CVX leverage token offering up to 3x exposure, designed to enhance trading efficiency and excitement.\ <br>

## 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://fxprotocol.gitbook.io/fx-docs/more/token-breakdown.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.
