# How to?

To use Minerva you need a MetaMask wallet connected to the Optimism network. For information on MetaMask, visit their [website](https://metamask.io/). 

MetaMask by default only supports the Ethereum network. However, when you connect MetaMask to Minerva, we will automatically configure MetaMask to work with Optimism. \
\
To perform transactions on Minerva or any other OP native protocol, you will need ETH for gas.
