However, it should be reminded that the Chrome installation file downloaded from the official website is actually a download and installer. After running this download and installer, the installer will download and install the full version of Chrome. If you want to download the full version directly, you need to add "?system=true&standalone=1" after the download address, which is the complete address, then the downloaded Chrome is the complete installation package.
If you can't access the official Chrome website above, you can try this website link:。

Click the fox head icon of MetaMask, and a privacy prompt will appear when you use it for the first time after installation, as shown in the figure.
Click the "Accept" button to display MetaMask's terms of service, as shown in the figure.
By default, the Accept button is gray, don't worry, click the drop-down bar marked by the blue box in the upper right corner and pull it to the bottom, and the button will be available. Click the "Accept" button to enter the wallet login page, as shown in the figure.
Here users have two options, one is to create a new DEN (DEN is a wallet stored in MetaMask encrypted with a password), the other is to import an existing DEN. Take creation as an example here, enter a password in the two password input boxes above, and click the "CREATE" icon at (1) in the figure to create a MetaMask wallet, as shown in the figure.
MetaMask will create 12 English mnemonics for users, be sure to save these mnemonics, be sure to save these mnemonics, be sure to save these mnemonics, when other wallets import this newly created account It is possible that these mnemonics are required.
After saving these mnemonics, click the button below to enter the wallet page, as shown in the figure.
MetaMask has automatically created a wallet address for the user, the address is "incomplete"? It doesn't matter, click the three dots on the right to open a wallet address related menu, as shown in the figure.
There are 4 items in the menu. The first item is to view all the transfer information of the wallet address on Etherscan. I will introduce you to Etherscan later. The second item is to display the QR code of the wallet, the third item is to copy the wallet address to the pasteboard, and the fourth item is to export the private key of the wallet. Various specific functions will not be introduced to you, and the relevant ones can be seen from the name. The fourth item will prompt the user to enter a password when exporting the private key, as shown in the figure.
The input box here is to enter the password entered when creating the wallet, and then click "Submit", as shown in the figure.
Click the red key to copy it to the pasteboard, the user must save it, don't lose it, don't tell others, the user must save it, don't lose it, don't tell others, the user must save it , don't lose it, don't tell others.Then click "Done" to return to the wallet page.
Click the green "Main Network" in the upper left corner of the wallet homepage or to select the network used by the wallet, as shown in the figure.
It should be remembered that when introducing Figure 4, MetaMask prompted that it is connected to the test network by default, but we can see from Figure 12 that its current version is currently connected to the main network, and there is no need to modify it here.
Click the settings icon with three horizontal bars in the upper right corner of the wallet to display the settings menu, as shown in the figure.
There are three options here, the first one is "Setting", where you can set the pricing method of the virtual currency in the wallet, as shown in the figure.
Click the drop-down menu marked by the blue box to select the pricing method, including legal currency and virtual currency, and users can choose according to their own habits.
The second option is "Lock", which can be clicked when the user temporarily leaves the computer to temporarily lock the wallet, and the user needs to enter the login password to unlock it again, as shown in the figure.
The previous article introduced some common settings of the MetaMask wallet. This section introduces the main functions of MateMask as a wallet.
Click the "Buy" button on the front of the wallet to enter the purchase Eth page, as shown in the figure.
As you can see from this page, MetaMask supports two ways to buy Eth, one is from Coinbase and the other is through ShapeShift.
Coinbase is the first bitcoin exchange in the United States to hold a formal license. It can buy bitcoin with US dollars, but it is currently not open to Chinese people, so this article will not introduce it.
ShapeShift is an account-less digital currency exchange platform that allows you to exchange your own virtual currency directly for Eth, as shown.
ShapeShift supports the conversion of BTC, 1ST, BTS and other virtual currencies into Eth. Those who are interested can try it out first, and an article will be introduced later.
Click the "Send" button on the homepage of the wallet to enter the page for sending Eth, as shown in the figure.
Fill in the destination Eth address to be sent to, the amount of Eth to be sent, and click "NEXT".
The so-called account management is actually the management of the Eth address. In addition to an address generated by default, we can also create new accounts or import existing accounts. Click the second icon from the right in the upper right corner of the wallet, as shown in the figure.
The first item is an existing account, the second item is "Create a new account", and the third item is "Import an existing account".
Click "Create Account" in the second row, the wallet does not seem to respond, but in fact, a new account has been created, as shown in the figure.
Click on a different account, and the wallet will switch to the corresponding account.
Click "Import Account" to import other accounts, such as addresses of other wallets, as shown in the figure.
You can choose to import through the "private key" method (the default method), enter the private key in the second input box (remember the private key introduced in Figure 11 earlier), and click "IMPORT".
Here, users are reminded that after logging in to MetaMask, your account is visible to all websites you visit. For your privacy, it is best to log out after using MetaMask. At the same time, it also reminds that MetaMask will log in to a test network by default. To use the real Ethernet network, users need to manually connect to the main network of Ethereum, which will be demonstrated later.
