What is MetaMask?
MetaMask is an application designed to facilitate access to the Ethereum Dapp (Decentralized Application) ecosystem.
MetaMask can also be used as a wallet to store Ethereum and ERC-20 Tokens.
By connecting MetaMask to an Ethereum-based Dapp, users can use their tokens and coins in games, exchanges, Defi, and more.
If you want to use OpenSea, then one of the conditions is that you must connect your account with a supported Ethereum wallet application, one of which is MetaMask.
How to Create a MetaMask Account
This may seem very confusing at first. But MetaMask is the simplest app you can use to access Dapp and NFT platforms like OpenSea.
So don’t be afraid to follow this tutorial. I will guide you step by step.
I also complete this article with screenshots of each step so that you are easy to follow. Immediately, follow the tutorial below to create an Ethereum wallet on MetaMask.
The first step you have to do is download the MetaMask extension. Currently, MetaMask is available for Firefox, Chromium, Brave, Microsoft Edge, and other Chromium-based browsers.
Visit the MetaMask site by clicking the button below, then download MetaMask according to the browser you are using:
If MetaMask is already installed in the browser, then you will see a new tab containing the greeting from MetaMask. Click the Get Started button.
Next, there will be two options, namely Import wallet and Create a Wallet.
If you’re reading this article, then I’m assuming you’ve never had a MetaMask account before. So click on the Create a Wallet button.
There will be a request from MetaMask to allow us to send some usage data. I recommend turning it down. Tap No Thanks. But if you don’t mind sharing useful information with the MetaMask developers, then click I Agree.
Next, create a password that you will use every time you open MetaMask. Make sure you remember this password carefully. If you forget this password, then you will have to reinstall MetaMask and import your Secret Recovery Phrase.
Next, a short video will appear containing an explanation from MetaMask on how to secure your wallet. Please watch.
If so, click the Next button.
In the next step, we will be given a Secret Recovery Phrase. This is the most important thing about your wallet.
Secret Recovery Phrase is 12 random words generated by MetaMask linked to your account.
It functions like a password that you use to log into social media accounts. So, don’t give this Secret Recovery Phrase to anyone, including your parents.
To display the Secret Recovery Phrase, tap the CLICK HERE TO REVEAL SECRET WORDS box.
The box will then display 12 words which are your Secret Recovery Phrase.
Write these 12 words on paper, then store them in a safe place. Or if you want to store it digitally, use an app like Bitwarden which offers encryption, that way.
Click the Next button to continue.
Next, you need to confirm the sequence of the Secret Recovery Phrase that you saved earlier.
Type each word in order, then click the Confirm button.
If the order is correct, then you will see the words Congratulations as below. Tap All Done.
Next MetaMask will display your Ethereum wallet as shown below:
Because we just created the wallet, the Ethereum balance is still 0 and no transactions have been recorded.
To send Ethereum to the wallet, please copy the wallet address and paste it on the exchange you are using.
And congratulations, you have just successfully created a MetaMask account.
Now you can use it to log in to Open sea to buy and sell NFT.
Not only that, but you can also use MetaMask to login in to other DApps.
