NFTs are tools that are simply not found outside the blockchain space, allowing for a wide range of applications and possibilities. Building a dynamic and randomized NFT is a great start for those looking to get into building collectibles, independent tokens, tickets, gaming applications, or anything the ERC721 token standard allows for. But what can we do with it now? Wouldn’t it be awesome to show off your newly minted randomized or dynamic characters?
We think it would be too. In this tutorial, we will walk you through all the steps to deploy your own dynamic or randomized NFT to the OpenSea marketplace. Here is an example of what it’ll look like at the end.
Let’s learn how to make something like the above!
ERC721 (also known as NFTs) define a framework for making tokens that are unique and different from each other (hence the term non-fungible), while the popular ERC20 standard defines tokens that are “fungible”, meaning the tokens are all interchangeable and guaranteed to have the same value. We will be diving a little deeper into how to build these and how the community represents them across platforms. You can read more in the OpenSea NFT Bible as well.

What Is Metadata?
In our last blog, we learned how to build random NFTs. Now we are going to take it to the next level using another important piece with the ERC721 standard: metadata.
All NFTs have what’s called metadata. You can read about this in the original ...
