# Convert to Private Tokens
The Privacy Portal allows you to seamlessly mint privacy-preserving equivalents of your public tokens, and subsequently burn them to redeem your public assets. Converting standard public tokens into private tokens requires a two-step approval process:
{% stepper %}
{% step %}
**Authorize the Conversion**
If you are depositing ERC20 tokens (not native COTI), you must first approve the Portal to access your tokens:
* Select your desired asset from the Public Tokens list and enter the amount you wish to convert. Click **Approve**.
* Your MetaMask wallet will request a spending cap authorization. Review the estimated network fee and **confirm** the allowance.
Approve Spending
{% endstep %}
{% step %}
**Convert to Private**
* After the spending approval is processed on-chain, click the **Portal In** button.
* Confirm the minting transaction in your wallet.
* Your new minted Private Tokens will appear in the **Private Tokens** dashboard.

## 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.coti.io/coti-documentation/coti-privacy-portal/user-guide/convert-to-private-tokens.md?ask=&goal=
```
`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.
