Hi, what are you looking for?



If you’re wondering how you can create and sell NFT’s on OpenSea, then you have come to the right place. Because today in this article, I will show you exactly how you can do that. Whether, you’re looking for a step by step guide or you’re stuck somewhere, I’ve got you covered.

Firstly, lets familiarize ourselves with some of the important Blockchain and NFT Key terms.

What are NFT’s? – NFT’s so called Non-Fungible Tokens are digital items, assets that can be anything from an original artwork, paintings, collectibles, to trading cards and even music, videos or any other digital assets. They are unique, and cannot be identical to each other. While, the data about NFT’s which include ownership data, description, name and so on, are all stored in the blockchain network. This is the reason why NFT’s cannot be duplicated, replicated and replaced. This makes NFT’s have the ability to be rare and unique.

Ethereum – Ethereum is actually a blockchain network where ETH or Ether is used as the main Cryptocurrency of the network. Today, Ethererum or Ether is widely used in NFT’s due to the possibility of Smart Contracts that allows smooth transactions between the users.

Crypto Wallets Crypto Wallets are essentially a Virtual Wallet in the form of desktop and mobile apps. This wallet allows us to store, receive and send Cryptocurrencies. Today, we can actually directly buy and sell Cryptocurrencies from a Crypto Wallet itself. Crypto Wallets like MetaMask allows us to do this.

Wallet Address – Your wallet address is a unique address that will be used to receive funds into your account in the form of Cryptocurrencies. This means when-ever you wish to receive funds from someone, you’ll have to use this unique address.

Secret Seed Phrase – This is essentially a list of 12 secret words given to you while you are creating your Crypto Wallet. This secret phrase acts as a recovery method incase if you lose your password or access to your Crypto Wallet. Remember to keep this secret phrase hidden in a safe location and should be only used to recover your Crypto Wallet. Not even the Crypto Wallet Company should ever ask you this phrase unless for the purpose of importing your wallet or recovering your wallet.

You’ll enter a page where you’ll have the option to add image, video, audio files and fill up data such as name and description. Upload your NFT image and fill those details.

To list your NFT, go to your collection page and choose the NFT you want to list and sell on the marketplace.

Next Press sell.

Here, you’ll be given two options, A fixed price listing and or a auction type listing.

A fixed price listing is where you’ll be setting a fixed price and the buyer has no other option but to buy your NFT on that fixed price.

An Auction is where different buyers compete with each other with their prices and the bidder who gets the highest bidding wins the auction, provided you choose the buyer and his price.

Once done, click on Post your Listing and follow the instructions given on your wallet.

Next, you’ll have to pay a gas fee before you can list your NFT. This is only a one time fee and the next time you won’t have to pay anything.

Once you’ve paid the gas fee, the transaction may take some time due to the market being busy.

Normally the transaction time depends upon the amount of gas you’ve paid. The gas fees ranges between $30 to $100 dollars and it may take between 60 mins to 24 hours.

That’s it, if you check after a couple of hours, your NFT should be listed on the OpenSea market place.

FAQ’s – Frequently Asked Questions

Q1. What if you want to create Multiple NFT’s on OpenSea?

A. Presently, you can only create one NFT at a time on OpenSea, However if you wish to create several versions of the same NFT and sell multiple times, so called “Edition Numbers”, you can do that too.

To do that, add “?enable_supply = true” at the end of the URL at the top of the page while creating your NFT and Press Enter. This should reload the page and a new option called Add Stats should appear.

Here you can set the supply of the NFT.

However, you cannot list all the NFT’s at once. OpenSea only allows you to list one NFT at a time individually. So you have to set the quantity to 1 for each versions of your NFT.
