Recently, the NFT trend has continued to gain popularity. NFTs, or non-fungible tokens, are blockchain-based tokens that validate the ownership and origin of digital items such as images, video files, and even physical assets.
NFT pictures are already being talked about at every turn. Celebrities publicize them, ordinary users are interested in them, and NFT-tokens themselves can bring millions of dollars to their owners.
Simple examples of this have been in front of us for a long time. The NFT-token with the first tweet in the history of Twitter by the company’s founder Jack Dorsey was sold for almost 3 million euros, and the world-famous Nyan Cat flying gif went under the hammer for 600,000 dollars.
OpenSea is a platform for NFT trading. The OpenSea platform allows you to sell, buy and create your own NFT tokens.
MetaMask is a non-custodial (OTC) crypto wallet that allows you to receive, store and send cryptocurrency assets.
If you sell something, it’s rational that the money should go to some account or wallet. And for that, the platform and the wallet must be connected to each other.
Well, here’s how to connect MetaMask to OpenSea.
How to install the MetaMask extension for a web browser
If you want to install the MetaMask extension for a web browser, you have to follow these steps:
- First of all, open your web browser and download the Metamask extension from the official website.
- Then, install and turn it on.
- After that, click on the “Get Started” button and select “Create a Wallet”.
- If you want to send Metamask data, click “I Agree”.
- Next, create your password and confirm it.
- Write down your backup phrase and confirm it.
- Finally, click “All Done” and sign in automatically.
If you decide to wait before buying Ethereum, you can sign out and come back later. If you’ve somehow logged out, all you have to do is click on the MetaMask icon to the right of the URL bar to access your account again.
Before you can create an account with OpenSea, you need to have some Ethereum in your MetaMask wallet. To buy Ethereum, you need to register an account with a cryptocurrency exchange such as Coinbase. By connecting your MetaMask wallet to the platform, you can get your new Ethereum.
However, you’ll have to wait up to 15 days before you can send your Ethereum to MetaMask. Thus, it’s better to start earlier.
How to connect MetaMask to OpenSea
All you have to do to connect your MetaMask wallet to OpenSea is to sign up for OpenSea using your MetaMask data. If you want to do so, you have to follow these steps:
- Open the OpenSea official website in your web browser.
- After that, click on the profile icon in the upper right corner of the webpage.
- Choose the MetaMask wallet from the list and link it to OpenSea.
- Now, click “Next” and add your email, username and other data.
Once you have completed these steps, you will be able to connect your MetaMask wallet to the OpenSea platform.
How safe is MetaMask
There are polar opinions about MetaMask’s security, but, first of all, security depends more on the user’s “digital hygiene” than on the developers of the wallet.
You should always consider what software is used on the device, who developed it, and what access that software has. Also, don’t forget about the apps that MetaMask connects to, some of them may request unlimited access to tokens stored on the wallet, and in case of malicious intent or hacking the app, all coins can be lost.
As an extra measure of security, MetaMask can be used with hardware wallets, such as Ledger. In this case, MetaMask works as an external interface, and all the user’s private keys are stored on the hardware wallet, and transactions are signed there as well. Even if intruders gain access to the computer, the user’s funds will be well protected.
What you need to know about OpenSea
OpenSea is the first NFT-marketplace, launched in 2017. The platform operates on the principles of a decentralized community: cryptocurrency wallets, addresses, and assets are controlled by users themselves. The marketplace protocol supports Ethereum, Polygon, and Klaytn Blockchain.
The feature of OpenSea is a wide range of categories. Popular categories include art, sports, collectible cards, and projects from famous artists. Also on the website, you can buy NFT in the form of audio, domain name, or 3D object.
OpenSea’s standard commission is 2.5% of the value of the NFT. The commission is charged to the buyer. The creator of the token pays the fee only for the first placement.
