# MetaMask Snap Setup

COTI MetaMask Snap is a plugin that enables you to execute encrypted transactions on the COTI Blockchain Network by granting Snap secure access to your [AES Keys](/coti-documentation/how-coti-works/advanced-topics/aes-keys.md).<br>

* When you click the **Unlock** button on the Private Tokens dashboard for the first time, a prompt titled “**MetaMask Snap Required**” appears. Click **Get COTI Snap** and follow the install flow. Use [dev.metamask.coti.io](https://dev.metamask.coti.io/) on **COTI Testnet** or [metamask.coti.io](https://metamask.coti.io/) on **COTI Mainnet** (the portal opens the matching link when you connect).
* Once the installation of COTI Snap is complete, click on the “Enable Snap” button.

## 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/metamask-snap-setup.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.
