# 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.

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.
