Welcome to the Maff instructions channel!
[4]
In this video, I'll show you the main points
you need to know about the MetaMask wallet.
[9]
How to install it, how to top up the balance
and make transactions, what settings to set
[14]
in it.
[15]
In general, how to prepare MetaMask for work.
[16]
There are timecodes in the video description.
[18]
If you are interested in a specific function
of the wallet, go directly to it.
[22]
Let's start by installing the wallet.
[24]
Opening the official website “metamask.io”,
the link is in the description.
[27]
I click on the blue "Download" button “”
[29]
Here, select the version to install, depending
on the browser or smartphone on which you
[32]
are going to use the wallet.
[33]
I will show the installation using the example
of the Chrome browser.
[37]
I click " install for Chrome”
[39]
A page opens in the Chrome Web Store.
[42]
I click "Install".
[44]
In the pop-up window, click " Install extension”
[46]
I wait until the file is downloaded and the
extension is installed.
[51]
When the installation is complete, the MetaMask
home page will automatically open and the
[55]
extension icon will appear.
[59]
I click " Start”
[60]
If you have already used the MetaMask, click
"import wallet".
[63]
You will need to enter a secret phrase.
[64]
I'll click " create wallet” to show you
how to create it.
[73]
Next, MetaMask offers to participate in a
program to improve the operation of the wallet.
[78]
Under the terms of this program, MetaMask
will send anonymous data about the pages where
[81]
you use the wallet and the actions on these
pages.
[83]
You do not have to agree to participate in
this program.
[88]
If you click " No, thank you”, you will
still be able to create a wallet.
[92]
If you have already installed and want to
disable this setting, I will show you how
[95]
to do it later in the “Security Settings
" section”
[97]
I set the password.
[98]
You need to save it, because you will use
it to enter the MetaMask in the future.
[102]
I check the box that I agree with the terms
of use and click " Create”
[106]
Next, an important point.
[107]
The wallet shows the secret phrase.
[110]
It is best to write it separately on paper,
or in a text file and store this file on a
[116]
flash drive or in the cloud with two-factor
authorization.
[117]
This phrase should not be shown to anyone.
[119]
Anyone who recognizes it will be able to access
your wallet.
[122]
It looks like this.
[124]
I show it as an example, since I will not
use this wallet anywhere else.
[127]
I save this phrase and click next.
[129]
You need to confirm that you have recorded
a secret phrase and place the words from this
[134]
phrase in the correct order.
[135]
I click " Completed”
[136]
So, we installed the MetaMask wallet.
[142]
To show the settings, I go to another wallet.
[147]
You can use the MetaMask in a window or in
full-screen mode.
[150]
When its easier to use window, but for the
video to show it in full screen.
[157]
I click on the 3 dots to the right of the
account name and select "Expand".
[160]
The interface, the location of all settings
will not change.
[162]
How to top up your wallet.
[163]
In MetaMask, you can create multiple accounts
inside a wallet.
[165]
Each of them will have a separate address
for replenishment.
[169]
Click on the account name to copy the address.
[171]
If it is more convenient to send by QR code,
you can click on the " Buy "button and select
[175]
"Direct deposit".
[176]
Send the Ether to this address and the wallet
will be replenished
[180]
If you have other wallets, you can connect
them and use them using the MetaMask.
[184]
Then you will not need to top up your account.
[187]
There are 2 options:
You can import another wallet using a private
[189]
key or a storage file.
[191]
It depends on the wallet you want to connect
to.
[193]
You can connect a Ledger or Trezor hardware
wallet.
[197]
Initially, only the Ether balance is displayed
in your wallet.
[200]
When you start using tokens, some of them
don't show up in your balance automatically.
[203]
For example, if you bought a token on a decentralized
exchange, the transaction was successful,
[209]
then this does not mean that the token balance
will be displayed in the wallet.
[216]
To display it, you need to add it manually.
[217]
I click "Add token" For example, I want to
buy "compound".
[219]
I enter "Comp”, choose from the options
I need, click" Next” and " add tokens”
[225]
Now the "Compound" balance is displayed in
the MetaMask.
[228]
If the search does not find the token you
need, you can go to the custom token tab and
[237]
find it at the smart contract address.
[238]
The address is best taken on the official
website of the project.
[242]
Usually you have to do this with little-known
tokens.
[244]
And usually the address of the smart contract
is enough, the other parameters are filled
[249]
in automatically.
[250]
If this does not happen, you can also find
them on the website of the project whose token
[252]
you want to add, from the developers of the
token, or on the website of the etherscan
[257]
blockchain browser, the link is in the description.
[260]
For example, I open etherscan and top erc20
tokens.
[262]
I choose UNI.
[263]
This is the address of the smart contract
that you need to copy and paste.
[265]
And this value is " Decimals”, that is,
the number of decimal places.
[266]
For UNI, it is equal to eighteen.
[267]
Under the symbol of the token wallet has in
mind for his Ticker.
[270]
In this case, UNI.
[271]
How to transfer ETH or tokens from a wallet.
[272]
To make a transfer, click "Send".
[273]
In this line, I enter the address to which
you want to send the coins.
[275]
You can add it to your address book.
[278]
Then this address will be displayed under
the address input line.
[282]
You can delete it in the settings in the “Contacts
" section.
[286]
If you click " Transfer between your accounts”,
you can transfer coins from one account to
[290]
another within the wallet, including imported
wallets.
[292]
Since the accounts have different addresses,
you need to pay a commission for such transactions,
[296]
just like for regular transfers.
[298]
In the "Asset" tab, I select what I want to
send.
[301]
I enter the amount.
[302]
Next, I need to select a commission.
[303]
MetaMask offers 3 options.
[305]
The higher the commission, the faster the
transaction will take place.
[309]
If you click " Advanced Settings”, you can
enter the commission manually.
[311]
If you compare the 3 options with those offered
by the gas tracker on the etherscan website,
[320]
the link to it is in the description, then
we will see that the MetaMask often shows
[327]
the commission higher.
[328]
Therefore, to save money, you can take a commission
from the gas tracker.
[333]
And if you need to urgently conduct a transaction,
you can specify a price slightly higher than
[343]
in the tracker and in the MetaMask.
[346]
I click "Save" to select my commission.
[348]
To submit a transaction, click "Next" and
" Confirm”
[349]
And now I will show you a few settings that
it is desirable to enable.
[353]
After that, you can assume that you have fully
configured the metamask and are ready to work.
[358]
Let's start with the section “Advanced.”
[359]
I click on the profile icon, click "Settings”
and select" Advanced”
[362]
String “Advanced gas control”.
[363]
With this setting, you will control the amount
of commission you pay for transactions.
[366]
It can be set immediately, without going to
the”Advanced Settings".
[369]
I enable this option and try to send the transaction
again.
[372]
Now the line for entering the gas price and
limit is available immediately.
[376]
You can enter your price and immediately click
next.
[379]
The following customization: Customize transaction
nonce.
[381]
Turn it on.
[382]
Now we can manually set the nonce number for
transactions.
[387]
You will need it to cancel or speed up a hung
transaction.
[389]
We recorded a separate video on this topic,
the link is in the description.
[393]
Next: Timer for automatic exit from the wallet.
[394]
By default, the exit from the wallet occurs
only when the browser is closed.
[398]
Here you can set the time after which the
MetaMask will automatically exit and ask you
[406]
to re-enter the password.
[408]
For example, I enter 30 minutes and click
save.
[410]
Now, if I haven't used my wallet for 30 minutes,
it will ask me to re-enter my password.
[417]
Now you can rest easy if someone gets access
to your computer, as they will still need
[423]
to know your password.
[424]
There is a “Basic”section in the MetaMask
settings.
[428]
In it, I advise you to change the following
points:
[434]
Currency conversion: By default, the balance
is converted to dollars.
[437]
Instead of dollars, you can choose rubles,
another fiat currency or cryptocurrency.
[440]
For example, if it is more convenient for
me to pay in rubles, then I choose them.
[443]
And now all the cryptocurrency on all MetaMask
accounts is converted into rubles.
[446]
Including the fees you pay for transactions.
[447]
Here, just choose how you prefer to count,
in dollars, rubles or other currencies.
[448]
The main currency: here we set the currency
in which the balance will be displayed first.
[450]
For example, when opening a list of accounts.
[451]
By default, this is Ether.
[452]
You can replace it with the currency that
the balance is converted to.
[454]
To do this, select "currency".
[455]
Now the balance is written not in Ether, but
in rubles.
[458]
Here, too, you set the settings that are more
convenient for you personally.
[461]
If it is more important to see how much your
cryptocurrency is worth, rather than how much
[469]
you have, then choose “currency” in the
settings.
[473]
For example, it is more convenient for me
to see the balance in cryptocurrency, so I
[478]
return the settings to "Ether".
[479]
Use Blockies Identcoin: This is the format
of the address icon in the upper-right corner.
[483]
If you enable it, you will have a unique icon
based on your secret phrase in this particular
[486]
format.
[487]
It doesn't affect anything.
[488]
Just the profile icon will be made on the
same principle as in many other wallets, for
[491]
example, in MyEtherWallet.
[492]
Next, the Security settings.
[493]
If you agreed to transmit data about the pages
where you use MetaMask when creating a wallet,
[499]
you can disable these settings.
[500]
I open the settings.
[501]
Section "Security and Privacy".
[502]
At the bottom there is a slider " Participate
in MetaMetrics” This is the same program
[508]
that we agree or disagree to participate in
when creating a wallet.
[513]
If you do not want to participate in it, just
switch this slider and the MetaMask will not
[518]
collect information about which sites you
visit and what you do on them..
[521]
The rest of the settings in the security section
should not be changed.
[525]
Show keyword: If you click here and enter
your password, you can view your secret keyword.
[530]
If you have lost the media with the secret
phrase, you can find it here.
[534]
Show incoming Transactions.
[535]
This is the setting for notifications of incoming
transactions.
[538]
It is enabled by default.
[540]
For example, when you top up your wallet,
a notification appears.
[542]
If you do not want to receive notifications
about receipts to the account, you can turn
[546]
it off.
[547]
I'll leave it on."
[548]
Use Phishing Detection.
[549]
This setting displays notifications if you
visit a phishing site.
[552]
Leave it on.
[553]
Account settings.
[554]
To open them, click on the 3 dots to the right
of the account name.
[561]
They are only relevant for the selected account
inside the MetaMask.
[563]
That is, I will now change the settings of
account 1 and they do not apply to account
[569]
2.
[570]
Connected Sites.
[571]
When you go to the sites of blockchain projects
and connect a wallet to them, the sites remember
[579]
it.
[580]
This is convenient when you regularly use
the same projects, because you don't need
[582]
to connect every time.
[583]
But there are sites that you visited once
or twice and forgot about them.
[587]
There are projects that have been missed.
[589]
There are projects that have stopped working.
[591]
And it is better that they do not remember
your wallet.
[595]
This opens a list of all the sites that your
account is connected to.
[600]
MetaMask draws attention to the fact that
these sites see the address of your account
[604]
The sites are listed in alphabetical order.
[606]
Those sites that you do not use regularly,
it is better to disable the MetaMask.
[612]
To do this, click on the trash icon.
[615]
If you have several accounts in the MetaMask,
then each of them will have its own list of
[620]
sites.
[621]
For example, I have a lot of sites on my first
account.
[624]
On the second - only one.
[625]
And if you deleted a site from one, it won't
be deleted automatically from the other.
[629]
For example, I delete a compound from this
account.
[634]
I go to the other one and open the settings.
[636]
And I see that the site has not been deleted
from the second account.
[640]
Other account settings
View on Etherscan.
[642]
The wallet statistics will open on the blockchain
browser.
[645]
Here you can view the history of all transactions
in the wallet, the balance of Ether and tokens
[653]
in dollars.
[654]
From here, it is convenient to view the current
prices for commissions in the gas tracker.
[657]
Account details - you can view the address
in the form of a QR code and a set of characters,
[664]
also view it on the etherscan website and
export the private key to use the account
[668]
through another wallet.
[670]
If you click on the account name, you can
rename it.
[674]
Just write a new name and save it.
[676]
This is only necessary for your convenience,
so that it is easier to navigate through multiple
[680]
accounts inside the MetaMask.
[681]
For example, one account can be personal,
another — for tokens, and the third-for
[684]
trading.
[685]
If you open the account settings from the
window mode, the “Expand " button will also
[690]
appear.
[691]
If you click, the full-screen mode will turn
on.
[694]
MetaMask has a built-in exchange of ether
for tokens and back.
[697]
The wallet analyzes prices and commissions
on 7 different decentralized exchanges and
[700]
selects the best offer based on the price-commission
ratio.
[703]
I click on "Swap".
[705]
At the top, I select what I want to sell and
enter the amount.
[710]
At the bottom, I choose what I want to buy.
[716]
To go to the advanced settings, click on advanced
options: here we can set the slippage.
[720]
Since the exchange rate is not constant, the
price may change during the exchange.
[728]
And the slippage means the percentage of the
price change that suits us.
[734]
By default, it costs 2% here.
[736]
If the price changes by 3% during the exchange,
the transaction will be canceled, but the
[742]
transaction fee will be deducted.
[744]
And if it is 1.5%, then you will successfully
receive your tokens.
[747]
Usually 2% is enough for the transaction to
go through.
[750]
But you can choose 1% or click custom and
write your own, for example 4%.
[753]
I leave 2%.
[754]
To view the terms of the exchange, click "Get
quotes".
[759]
The same check of prices and commissions on
7 decentralized exchanges begins.
[766]
We get the result.
[770]
The wallet shows how much we can buy for the
amount that we put up.
[783]
This is
the best quota, that is, the best offer.
[797]
You can click on quotas, i.e. other exchange
options, and compare them.
[805]
The price also includes the commission of
the MetaMask itself of 0.875%.
[822]
The expected and maximum commission is written
at the bottom.
[825]
The expected commission cannot be changed,
and the maximum commission can be changed
[834]
by clicking on " edit”
There are 2 options for transaction fees
[840]
Here you can also click "Advanced" and set
your maximum commission.
[844]
Here you do not need to go to other sites
and see what commissions are currently in
[858]
the network.
[859]
These settings will not affect the speed.
[860]
We simply set the maximum amount we are willing
to pay for the commission.
[864]
But I would not put more than what is written
in the basic settings.
[869]
It is better to choose within the limits.
[871]
So, in this video, we have figured out how
to install and configure the MetaMask wallet,
[880]
and how to use it.
[886]
On our channel, there are other videos about
this wallet, in which we tell you how to cancel
[892]
a suspended transaction using a MetaMask,
how to protect it from hacking and from dangerous
[896]
smart contracts.
[897]
The links are in the description.
