When you are researching blockchain games and crypto assets, do you see the term MetaMask?

MetaMask is an online wallet for storing crypto assets.

Because of its ease of use, it is used in many platforms such as blockchain games.

TJ

Because it is used by so many people, it is no exaggeration to say that MetaMask is one of the essential tools.

Therefore, in this article, we will explain how to register MetaMask and its basic usage, using diagrams.

How to register a MetaMask

MetaMask is a dedicated virtual currency account that can be used as an extension to your Internet browser (Google Chrome, Firefox, Safari, etc.).

So you must first add MetaMask as an extension to each browser.

In this article, I will explain using the Google Chrome screen, which is the easiest to use.

TJ

There are many fake MetaMask products on the market, and if you install them by mistake, you may lose information or bring your entire virtual currency.

So be sure to download MetaMask from the official page.

Also, there is no app for MetaMask ( on the contrary, the app is a scam).

TJ

I hear the fake MetaMask is a faithful reproduction of the real thing, so watch out!

STEP

First, if you do not have Google Chrome on the device you are using, please install it from the official page below.

Passwords are very important, so let’s proceed with increased attention.

STEP

After that, an explanation video will appear that says, “Recovery phrases are important things that no one can tell.”

Once you understand the importance of the password and recovery phrase, click [ Next ].

Metamask7

What is a “recovery phrase”?
The recovery phrase is a “master key” to your wallet (account) and funds.
If it is lost or leaked, the funds cannot be withdrawn or will be stolen.
So, let’s manage it strictly.

The recovery phrase is required at the following timings.

When the computer you are currently using is initialized
When logging into MetaMask from a terminal other than the one used for registration

TJ

If you forget, you will never be able to log in again under any circumstances.

Therefore, it is recommended to leave it not only in the computer but also on the cloud, notebook, memo paper, etc.

*Basically, I recommend that you keep it on paper in a place where you will never forget/lose it.

STEP

TJ

Note that since you will be using MetaMask more often in the future, it is convenient to pin it for immediate operation.

Pinning can be set by the following procedure.

Click on the extension button (puzzle mark) in the upper right corner of the Chrome browser.
Check that the MetaMask item appears.
Click on the pin button on the right side of the screen
When the “Fix” button turns blue, you are done.

[Caution! ] A scam to find out the recovery phrase

Anyone with a recovery phrase is free to move the funds in MetaMask.

So, try to get the recovery phrase out of them. There are a lot of scams out there.

Main fraudulent methods
Claiming to be the operator of MetaMask or trying to create a website that looks just like MetaMask to get you to fill out the form.
Attempting to get a recovery phrase from someone pretending to be at the support desk
They ask me to give them a recovery phrase because they will transfer it to my account in an airdrop campaign (free distribution of virtual currency).

We are aiming for recovery phrases by all means.

Never tell anyone whatever happens!

TJ

If you have the time and wisdom to do that, I wish you’d spend it on something different!

How to use MetaMask

Now that you have registered MetaMask, we will continue to illustrate how to use it.

TJ

MetaMask has four functions: (1) deposit, (2) transfer, (3) exchange currency, and (4) add chain.

How to use MetaMask (1) Make a deposit

The first and easiest way to use the system is to make a deposit.

Tap the fox icon in the upper right corner of the browser and click the button on the screen that appears to copy the MetaMask address.

TJ

Then, from an external site such as a crypto asset exchange, set the address you just copied as the destination/transfer address, and you are done.

Note that MetaMask only allows deposits and withdrawals of ETH (Ethereum) by default.

For example, if you send Bitcoin to a MetaMask ETH address, the Bitcoin you would have sent will disappear*.

*The technical term for this is “self-GOX.

TJ

If you wish to perform operations other than ETH, you must follow the procedure described in usage (4).

How to use MetaMask (MetaMask) (2): Transferring money

The second use is remittance.

Open the MetaMask screen as you did for the deposit, and click [Transfer Money].

You will then be asked to enter the destination address. Enter the address of the crypto asset exchange, etc., and click [Next] to send the money.

TJ

When sending money, please note that a fee called a “gas fee” is required when trading in crypto assets.
If there is not enough commission, the screen above will appear and the money cannot be transferred.

How to use MetaMask (2): Exchanging currencies

In addition to deposits and withdrawals of crypto assets, MetaMask also allows for the exchange of crypto assets for each other.

Click [Swap] on the MetaMask screen, select the source and destination crypto assets to convert and specify the quantity.

Set slippage (the larger the slippage, the higher the commission, but the easier it is to confirm the order) in Options and click 【Check Swap】.

How to use MetaMask (MetaMask) 4: Adding a chain

TJ

The last use is to add a chain (network).

A chain is simply an economic sphere, and transactions are recorded/executed on the ETH chain based on ETH.

The ETH chain had a long history and was very popular, but as the volume of transactions grew enormously, fees became a problem.

TJ

Therefore, in order to reduce fees, the development of chains derived from the ETH chain, represented by Polygon, was promoted.

MetaMask can only handle the ETH chain by default, but additional settings can be made to support other chains.

To do this, click on “Ethereum Main Net” on the MetaMask Home screen, and then click on “Add Network”.

You will then be asked to enter each piece of information.

TJ

Please copy and use the information below for typical chain information to enter.
