# Swap BOB with Metamask Swap
{% hint style="info" %}
In this example we swap MATIC for BOB tokens. You can swap any supported tokens for BOB or vice versa using Metamask :fox:. BOB is also available to swap on Ethereum mainnet.
{% endhint %}
1\) Open MetaMask. Login to your Account and connect to the [Polygon Network](https://wiki.polygon.technology/docs/develop/metamask/config-polygon-on-metamask/). You can initiate swaps wherever you are on the internet, you do not need to be connected to any particular site.
2\) Press the **Swap** Icon.
3\) Enter token swap details.
1. The token from the dropdown (MATIC).
2. The amount you would like to swap (20).
3. Type in BOB to find and select the BOB token.
4\) Press **Continue,** or to double check you are using BOB, you can verify BOB on [polygonscan](https://polygonscan.com/). The BOB token contract is [0xb0b195aefa3650a6908f15cdac7d92f8a5791b0b](https://polygonscan.com/token/0xb0b195aefa3650a6908f15cdac7d92f8a5791b0b)
5\) Press **Review Swap**.

## 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://bob-docs.zkbob.com/bob-info/metamask/swap-bob-with-metamask-swap.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.
