# How to create a MetaMask wallet

First step to invest in Growi Finance protocol is to have a crypto wallet

This is a step-by-step guide to create a MetaMask wallet. MetaMask is the most commonly used wallet, it allows you to store cryptocurrencies on the Ethereum, BSC, Optimism, or Arbitrum blockchain, among many others.

To create your Metamask wallet, follow these simple steps:

1. Download and install the Metamask extension in your browser. Always make sure you’re downloading files and interacting with official pages of protocols/companies. (<https://metamask.io/>).

2. Create a new wallet: Open MetaMask, click “Create a wallet,” and follow the instructions to set a password. Safely store your recovery phrase/secret key offline, and never share it with anyone.
3. Metamask will ask you to confirm the secret key before completing the process. Once done, you’ll have your wallet active.
4. By default, the initial blockchain is Ethereum. You’ll need to add the Arbitrum One blockchain to interact with our protocol. Click on the button in the upper left corner where it says “Ethereum Mainnet”, and then, click on “Add network”.
