# How to Buy USDu

USDu, the yield-bearing stablecoin issued by Unitas, can be acquired on the secondary market or minted directly through the Unitas protocol.

Via the [Unitas dApp](https://app.unitas.so/buy) interface, non-whitelisted users can seamlessly acquire USDu by exchanging other stablecoins (e.g. USDC, USDT) through integrated onchain liquidity sources.

#### Here's how it works:

* The user selects a stablecoin they wish to convert into USDu via the Unitas UI.
* This approach abstracts away the complexity of manual trading, allowing users to simply use stablecoins as input assets.
* The resulting onchain imbalances create arbitrage opportunities for whitelisted market makers, who can then proceed with the minting process.
* Minting USDu involves sending eligible backing assets to the Unitas protocol to receive newly issued USDu.
* Redeeming USDu involves burning USDu to withdraw the underlying backing assets.

Only whitelisted institutional participants can directly mint or redeem via the Unitas Mint Portal or API. Access to this functionality is gated and managed via allowlist controls to ensure system integrity and capital efficiency.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.unitas.so/guides/how-to-buy-usdu.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
