How to Create an NFT on OpenSea
Creating a non-fungible token (NFT) on OpenSea is easy and intuitive. Users just need to select the genre of their collection, set up a crypto wallet, choose a blockchain, and list their NFT(s).
Currently, OpenSea is one of the most popular NFT marketplaces, hosting over 1.2 million users and 80 million NFTs. It simplifies the buying, selling, and minting processes, allowing anyone to get involved in this lucrative technology.
With these incredible data, the most impressive thing about all this is that to participate in OpenSea you only need a device with a connection to Internet and a Web3 wallet. With this you will be able to buy, sell and even create your own NFTs and show them to the world.
In this article, we will provide a step-by-step tutorial on how to mint NFTs on OpenSea.
What do you Need to Mint an NFT?
In addition to the NFT itself, you will need a crypto wallet to create and mint your NFT. “Minting” an NFT is the process of writing a digital item onto the blockchain. This establishes your immutable record of authenticity and ownership.
Crypto wallets are a fundamental tool of web3. Your wallet acts as a private key that allows you to interact with decentralized applications, buy NFTs, and browse the web3 universe. Each blockchain has specific wallets that you can use to transact on them. For example, MetaMask is a wallet used to interact with the Ethereum blockchain and Phantom is a wallet used to interact with the Solana blockchain. OpenSea supports a wide variety of wallets.
Next, choose a blockchain to mint your NFT on. OpenSea currently supports the Ethereum, Solana, Polygon, Klaytn, Arbitrum, and Optimism blockchains, and each of these blockchains have different gas fees associated with transactions on their networks.
Then you can create your collection. This is the fun part! Decide what your NFT collection is about. Is it a piece of art, a collection of profile pictures, sports memorabilia, group membership, or something else entirely? Once you decide, create your collection by naming it something unique that represents your work and describing it. You will also be asked to choose a category and provide relevant social media links.
Once your crypto wallet is set up, you’ve chosen a blockchain, and your collection is built, you’re ready to mint your NFTs!
Create an NFT for Free on OpenSea
Yes, you heard it right. You can create an NFT for free on OpenSea. Simply follow these steps:
1. Connect With OpenSea
Using OpenSea is very easy since you only have to meet the following requirements:
- A device (PC, laptop, tablet or mobile) with an Internet connection
- A Web3 wallet (ex: MetaMask, Wallet Connect or similar) that operates within the networks ETH o Polygon.
To enter OpenSea, the first thing you must do is go to its official website. Once there, all you have to do is go to the wallet icon on the web and click on the MetaMask option to connect to the wallet. When selecting the wallet, you only have to accept the interaction with it and with this you will already be completely connected to the market.
2. Select “My Collections” on OpenSea
On Opensea, click your profile icon, then select “My Collections” from the dropdown menu.
3. Click on the “Create a collection” button.
4. Add the details of your collection, such as the logo, description, social media links, and banner. Set your creator earnings.
5. You can also select which blockchain to use by clicking the dropdown menu and selecting Polygon. Polygon does not have gas fees when creating NFT collections on Opensea because it is a layer 2 solution that uses Ethereum smart contracts to verify and validate transactions. This means that transactions are processed off-chain, which speeds up the process and reduces fees. This is a great solution for those who want to create an NFT collection but do not want to pay the high gas fees associated with Ethereum. Polygon supports Polygon ETH, but you can also add other payment tokens in addition to ETH.
6. Now that your collection has been created, you can add your NFTs by clicking the “Add Item” button in the top right corner of the screen.
7. You can now create a new NFT item by uploading your file and customizing your NFT details. One of the benefits of Polygon is that it allows you to create a semi-fungible token (NFT) for free.
By increasing the supply of your NFT, you can increase the number of copies that can be minted, meaning your item can be owned by multiple wallets.
8. Once you’ve hit the blue button to Create your NFT, you’ll see a confirmation window appear.
Does it cost money to create an NFT?
Sometimes. Depending on the blockchain, creators will need enough cryptocurrency in their wallets to cover gas fees for the transaction. But, on Ethereum and Polygon, OpenSea offers something called “lazy minting,” a process by which creators can avoid paying gas fees to mint NFTs.
Lazy minting and the OpenSea collection manager allows creators to make NFTs without the need to pay any upfront gas fees. This process works because the item is not transferred up the chain until the first purchase or transfer is made from the creator to the first collector. Collections are also free and instant.
