What is OpenSea?
OpenSea is a peer-to-peer marketplace for trading NFTs. NFTs can be anything from works of art to virtual land, in-game items, and other utility tokens. By collecting NFTs from multiple blockchains, OpenSea acts as a one-stop shop where most collectors go to discover and purchase NFTs.
How to Mint an NFT on OpenSea
Step 1: Connect your wallet
Click on the wallet icon at the top right and connect your wallet. (If you’re using a Rainbow Wallet, you can connect it using the WalletConnect option)
Step 2: Create a Collection
A Collection is like a folder that allows you to group NFTs that are part of the same series. Each collection has a unique link that displays only the NFTs that are part of that collection. If you are minting a lot of NFTs for different reasons, creating a collection is a good way to organize them and also makes it easy for collectors to access. For example, here is the Rabbithole Quest NFT collection on OpenSea
OpenSea supports a range of file types like JPG, PNG, GIF, MP4, WEBM, MP3, and more.
The maximum file size supported is 40 MB.
Add the name of the item, an external link, and a description.
Markdown is supported in the description.
Select the Collection that you’d like to add the NFT to.
If you’re creating an NFT series with multiple NFTs that have different traits, you can use the Properties, Levels, and Stats options to include them. This will allow users to calculate how rare a particular trait is.
Add Unlockable Content
This content can only be unlocked by the owner of the NFT. You can add a link to a private discord server, link to the high-quality file, etc
Select this if your item is NSFW
You can choose either Ethereum or Polygon.
Minting on Ethereum is expensive due to the transaction and gas fees.
Minting on Polygon is very cheap.
If you choose to mint on Ethereum, you can only choose to mint 1 NFT. Minting on Polygon allows you to mint multiple copies.
Click on Create.
Your NFT is now live! You can now choose to list it for sale. Listing it is free. Add the price of the NFT and sign a gasless transaction with your wallet to confirm the listing.
Congratulations! You have now minted an NFT on OpenSea!
