Uploading an NFT to the blockchain is known as “minting,” and it’s a pretty simple step overall. Rarible and OpenSea both have roughly the same process here. Following the instructions on your NFT marketplace’s website, you will upload your NFT into your wallet, add details like the description and a number of others—and then that’s pretty much it.

Underneath those fields, you can choose a collection for your NFT if you’ve set one up, as well as add properties, levels, or stats that can basically act as metadata. If you’re selling an NFT that could act as a video game character, for instance, this is where you’d put in their information. If you’re selling a piece of art, you could use the properties panel to add information about it, such as the medium, year, etc. However, all these fields are optional, so a lot of people will probably be able to ignore them.
OpenSea also lets you add text that acts as unlockable content, which the buyer / owner of the NFT will be able to see. You could use this toggle-able field to include something like an invite link to a private Discord, a code to redeem something on an external website, or even just a message thanking them for buying.
