# Mint & Burn Process

## Mint Process

The minting process in PumpBTC represents the creation of new wrapped tokens, specifically $pumpBTC. This process is initiated when a user deposits assets into the PumpBTC system. When a user commits their assets, they are transferred directly to the partnered Custodian, not to PumpBTC itself. Upon receiving these assets, the Custodian triggers a mint transaction to the PumpBTC smart contract. This action results in the creation of new $pumpBTC tokens at a 1:1 ratio to the deposited assets. Finally, these newly minted $pumpBTC tokens are transferred back to the user.

## Burn Process

Burning in the context of PumpBTC refers to the process of redeeming Bitcoin in exchange for $pumpBTC tokens. This operation is essentially the reverse of the minting process and plays a crucial role in maintaining the system's equilibrium and token integrity.

## 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://pumpbtc.gitbook.io/pumpbtc/tech-specs/mint-and-burn-process.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.
