Now you are reading the second article of our NFT tutorial series. If you don’t know about NFT, I recommend you to read first article before this.

What is NFT Meaning? Explained (NFT Crypto)

In this article, I will cover how you can start selling NFTs on OpenSea in order to make money from them. There are several NFT marketplaces where you can buy and sell your digital assets. Opensea is the first and most expanded marketplace for NFTs.

Opensea uses both Ethereum and Polygon blockchains for NFT listing so you can use Polygon for listing your items without any Gas fees. That means you can start selling NFTs at zero cost, so it’s completely free. Let’s start to sell on Opensea.

How to Create MetaMask Wallet

To log in to the Opensea platform, you need to have a crypto wallet. You can use any kind of crypto wallet to sign up to Opensea but Metamask browser-based wallet is the most preparable way to connect.

It is also very useful in our future videos as well, so I recommend you create a Metamask account. You can also add your other crypto wallets to Metamask.

• To create a Metamask account, you have to use the Chrome browser because it is a Chrome extension.

First, go to the Metamask website and download the Chrome extension to your browser. You can also get it from the Chrome web store but there is some risk, you may get spam or fake Metamask extension.

• After you add it to your Chrome browser, click on the Metamask icon on the top right corner of your browser.

You will redirect to this welcome page. If you have an old Metamask wallet you can add it or you have to set up a new one.

• I didn’t have one so I am going to click the “Create a wallet” button.

• You can read and click “Agree” to this statement.

• Create a strong password for your wallet.

This is an introductory video from Metamask, if you are interested watch and click on “Next”. This is the most important one, you can see your secret recovery phrase by clicking on this blurred box.

Keep it in a secure place, write down or remember it. If you lose this, you can not recover your wallet with your money or cryptocurrencies. Also, someone has stolen your secret recovery phase, he can access your wallet and control your transactions.

Next, confirm your “Secret recovery phrase” to verify it. Click these words according to your phrase. Now it is done, your Metamask wallet is ready for transactions.

Connect Metamask to OpenSea

Ok let’s go to the next step, now you can log in to the Opensea using your Metamask wallet. Click the “Create” link at the navigation bar, then you have to connect to the Metamask wallet. It is finished, now you have an Opensea account. You can customize your account and update your details.

After that, you can start listing your items on Opensea and sell them on it. Before listing a single item you have to create a collection. Here you have to add a logo image and enter a name for the collection. This name should be unique otherwise it will not be approved.

Add a description and select a suitable category according to your items for this collection. You can also set up a creator earning percentage that is the percentage you are going to get when it resells over time to time in the blockchain.

This is a unique feature of NFTs, you can get this percentage lifetime no matter how many times your NFT is being sold. You will get this proportion for each and every transaction.

In this field, you have to enter your wallet address. Copy it from the Metamask and enter. Suppose you want to list items on Opensea without gas fees, select Polygon blockchain.

In the Ethereum network, you have to pay gas fees for every listing on Opensea. After that, you can click the “Create” button to finish.

List NFT on OpenSea & Sell

Now you can list your items in this collection. After you enter the newly created collection, you can see a button called “Add item”. Upload your NFT, this can be a Photo, Vector, GIF, or Video. Fill in the other details, name, external link, and description. Then you can create the listing.

After successfully listing the item, you can find the “Sell” button in the upper right corner of the page. Click it to start selling your item. You can enter any amount you wish to sell your NFT and also the duration of the listing.

When you do this process for the first time, you can see an “Unlock” button. Click it first and unlock the transaction from Metamask. Then you are able to list as normal.

Ok, now you listed your first NFT on the blockchain. Wait for a new order for your listing. In future videos, you can learn to generate more than 10000 NFTs in a few minutes. Stay with MineX.
