Do you have some cool digital designs in the work but you’re not sure how to transform them into non-fungible tokens NFTs? Then this blog post is for you! The process of ‘minting’ or ‘tokenizing’ your artwork on a marketplace is not complicated. After reading this short guide, you will be able to start to display and market your NFTs in no time.

There are many benefits to converting your (digital) artwork into an NFT. We’ll mention just a few here below since the objective is to help you enter the space, not convince you that it’s a fit for your specific situation. 🤓

👀 More visibility
🔐 True ownership over your work
💸 You can receive a commission every time your NFT is resold. If the value of your NFT increases when resold, you will be able to benefit from it

This short step-by-step guide will help you transform your artwork into an NFT on OpenSea. This platform is the largest NFT marketplace, so it is the best marketplace to demonstrate the process of turning art into an NFT. This process is called ‘minting’!

Step 1 — Connect your Crypto Wallet

The first step is to sign into OpenSea, to do so you just need to connect your crypto wallet.

If you don’t have a crypto wallet, you will need to download one beforehand. Wallets essentially allow you to interact with decentralized platforms, like OpenSea. With your wallet, you will be able to send and receive ETH, which is the cryptocurrency used to buy or receive payments for NFTs on the platform. We recommend using Metamask as it is a very simple wallet to use, but you can choose from 11 different options on the platform. It’s up to you!

Step 2 — Create your collection

Once your wallet is connected to the platform, the next step is to create your collection.

  • Go to your profile on the top right corner and select ‘My Collection’.
  • Then press ‘Create’ to start a new collection.

Your collection is gonna work like a digital art portfolio or an album. Once it’s created and you start growing it, you can basically just scroll through the different NFTs added on it.

Step 3— Mint your first NFT!

After creating your collection, just press on ‘Add New Item’ to mint your first NFT. Upload your NFT and choose a name for it. You can then add properties, levels, and stats which are basically additional descriptions for your digital collectible. Press create and that’s it! Your NFT is on display, where you can check all of its details. You can keep the NFT for display, or sell it.

In order to sell it press the ‘Sell’ button on the top right corner. For the first NFT you sell on OpenSea, you will need to pay a gas fee before you can list it. You can either set a price for your NFT or auction it (you have the option to add a minimum bid). Then press post listing and sign the transaction. Now you just need to wait for a collector to acquire your art!

Final step — verify the storage of your work

There is one last thing that you should know about minting: the storage of your NFT is very important. If your NFT is stored on a centralised server, rather than on the blockchain, IPFS, or Arweave, then your NFT will be vulnerable to tech issues. There is one tool to verify the storage of NFTs on Opensea, called Nifty Scanner. This browser extension developed by the Indorse team will tell you in detail if your NFT is safely stored.

😎 You should now be able to start minting NFTs like a pro, good luck!
