# acreBTC Deposit Token

**acreBTC is a non-rebasing ERC4626 deposit token**, which represents bitcoin deposited into Acre.

The ERC4626 standard is a tokenized vault standard, which is designed for the efficient management of vaults and rewards.

### How Rewards Accrue

**As Acre vaults generate rewards, these will automatically accrue to the acreBTC ERC4626 vault.** When a user withdraws their bitcoin, or redeems acreBTC, they will receive their deposited bitcoin amount--plus rewards that have accrued during the period of their deposit.<br>

### Rebasing vs Non-rebasing tokens

**acreBTC is a non-rebasing token, which means that the balance of acreBTC does NOT increase in a users wallet as rewards accrue.** Instead, the amount of bitcoin that acreBTC can be redeemed for increases.

### Using acreBTC outside of the Acre DApp

You can view your acreBTC balance anytime inside the Acre DApp. Note that there is no way to mint or move your acreBTC deposit token outside of the Acre Dapp. Any future decision to allow for minting or moving acreBTC will be voted on by the Acre DAO. <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://docs.acre.fi/key-concepts/stbtc.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.
