Web 3.0 Basics - How to Set up a Metamask Wallet

Setting up a Wallet on Metamask

The first article in this series introduced the main concepts related to Wallets, now it is time to move on to the practical side.

Let's proceed to set up a Wallet, specifically a Web Wallet, on Metamask.

To do this, enter the website and download the appropriate version for your browser.

Once you have added the extension you can proceed to create the account (without wasting too much time playing with the fox).

Once this is done, you need to set the password.

Best practices for the creation of a secure password:

As a general rule, it is advisable to:

● Do not share your passwords.

● Do not write them down, or at least do not leave them lying around

● A minimum length of 15 characters

● Use a combination of uppercase letters, lowercase letters, numbers and special characters (for example: !, @, &, %, +)

● Avoid data that are personally relatable (birthdays, names of

relatives/ pets, nicknames)

● Enter characters randomly, avoiding sequences of characters (e.g., "qwerty" or "1234")

● Change passwords periodically and do not use the same password for multiple accounts

Having entered and confirmed the password, we are shown the Wallet Recovery Phrase.

It is imperative to copy it and secure it, possibly making multiple copies, because this represents the only way of recovery for one's wallet.

Obviously, you should never share it and it is critical not to lose it.

A safe way to do this is to prepare partial copies of the seed phrase and keep them in separate places, perhaps dividing the 12 words into 3 copies of 4.

It is important to copy them (in the order they are showed) and put them in a safe place, because losing these will make it impossible to have control of your Wallet.

Once you have confirmed the Seed Phrase, the procedure is complete.

The primary Web interface looks like this:

At the very top there is a section showing the so-called Address, which as you may have guessed is your Public Key.

By providing this address to a sender you can receive transactions. Conversely, to send transactions you need to know the recipient's address.

Now that our Metamask Wallet has been set up, we may need to operate on Blockchains other than Ethereum - but compatible with it - such as Polygon.

The next article will then cover the procedure of adding a new Network on Metamask.
