NFT 101: An Introduction to NFTs

What is an NFT? What does NFT stand for? Why are NFTs selling for millions of dollars? These are some of the questions you may have when new to the NFT community. In a short span of time, Non-fungible tokens, or NFTs, have made their way into sectors of all kinds, including art, finance, sports, fashion, and gaming, to name a few.

NFTs gained prominence in 2021, especially after NFT artist Beeple scripted history by selling his NFT art for $69 million. Since then, NFTs have taken the digital world by storm, with artists, celebrities, global brands, tech giants, and more hopping on the bandwagon. 

If you are new to the crypto and Web3 world, NFTs may sound overwhelming (seriously, what are they?) But don’t worry—we have got you. This ultimate NFT guide is all you’ll need to know everything you ever wanted to know about NFTs and more. In this guide, we will take you through what NFTs are, the tech behind them, how NFTs are created and sold and whether you should get involved. Follow any of the links in this article to read the full and in-depth articles for each topic.

So, let’s dive right in!

What is an NFT and how does it work?

An ‘NFT’ or ‘Non-Fungible Token’ is a blockchain-based asset linked to a digital or physical object and serves as an authentic proof of ownership. In short, they are:

  • Non-interchangeable
  • Immutable
  • Traceable

Notably, NFTs can be pretty much anything from images, music, and videos to gifs, to physical objects. As a result, they now have wide use cases as fundraising tools, event tickets, exclusive merch, and much more. If you want to learn more about the details, make sure to check out our first guide on what an NFT is in the first place!

Is it worth buying an NFT?

 There are a couple of reasons why NFTs sell like hot cakes:

  • Traceability and transparency: Each token is completely unique—much like a digital signature. And thanks to transparency conferred by blockchain technology, you can easily track an asset’s ownership and authenticity.
  • Royalties:  Non-fungible tokens make it possible for artists to create and sell their works independently, without having to go through middlemen. What’s more, they can earn lifetime royalties through every secondary sale of their digital asset.
  • Potential Profit: Investing in non-fungible tokens has the potential to help you gain high returns. For example, CryptoPunks, which were originally available for free, today costs at least $135,000 (at the time of writing).
  • Community: Community is an integral part of most NFT projects.

The Metaverse and Digital real estate

NFTs are also an important part of what the metaverse is. Essentially, a metaverse is a 3D virtual world that incorporates a slew of tech such as virtual reality (VR), augmented reality (AR), and mixed reality (MR) into our daily lives. Within the virtual world, non-fungible tokens represent a range of items including avatars, wearables, virtual land, vehicles, weapons, and so much more.

Digital real estate usually serve as unique plot of land in the metaverse, with non-fungible tokens representing each parcel of land. Just like in the real world, you can do pretty much anything with your digital real estate. You can build virtual houses, shops, and galleries, set up casinos and even host parties!

To help you learn about the most popular metaverses, we’ve created some highlights on the biggest of them:

 Then, if you’re considering buying virtual land, make sure follow our outline in: How To Buy Metaverse Land.

How to Choose a Crypto Wallet For NFTs

To get involved for real, you’ll need to choose a crypto wallet that supports NFTs. This is where you will safely store and transfer your digital assets and crypto. Primarily, there are two types of crypto wallets. Firstly, Software (or hot) wallets like Metamask store your NFTs online. Then hardware ( or cold) wallets, like Ledger,  store them offline. 

To help you make your own choice, we’ve compiled a list of the best crypto wallets for NFTs.

Do I Need Crypto To Buy NFTs?

Most NFT marketplaces only allow you to trade digital assets using crypto. So, yes, there’s a high chance you will need some. As most digital assets are based on the Ethereum blockchain, its native currency, Ether (ETH) is the leading crypto used for NFT transactions. However, due to ETH’s high transaction costs and high carbon footprint, you may want to consider other blockchains.

Solana (SOL), Tezos (XTZ), and Flow (FLOW) are other blockchains that support NFTs, with the former being the most popular.

Finally, there are some marketplaces that don’t use crypto at all. If that’s more your style, you may want to consider the Veve Marketplace.

Which NFT Marketplace is Best?

To buy most NFTs, you’ll need to find an appropriate marketplace. Now, while there is a whole range of marketplaces to choose from, each caters to a specific need. To choose the best marketplace, read our in-depth guide on the best NFT Marketplaces. To start with though, here are the basics:

For beginners on Ethereum, we recommend starting with the most popular marketplaces. Namely, OpenSea, Rarible and LooksRare. These are the generic marketplaces with the most volume on Ethereum, and likely the most accessible.

However, if you are looking for 1/1 artworks, curated marketplaces such as SuperRare or Foundation are the better choice. Similarly, for music NFTs you’ll want to consider music-native platforms. Some of the best options include: Catalog, Royal and OneOf.

Finally, Nifty Gateway is a great place to find drops by celebrities and top-selling artists. 

Marketplaces on Alternative Blockchains

Looking to dip your toes into non-fungible tokens but Ethereum prices scared you away? Why not try some NFT marketplaces on Solana?

Namely, Magic Eden and Solsea are some community favourites. If you want to know more, we’ve created an all encompassing guide on how to buy solana NFTs. Plus, don’t forget our introduction to the top NFT collections on Solana for some great investment ideas.

How to Invest In NFTs

There are many reasons why someone may want an non-fungible token, but how do you know it’s a good investment? Well, from respected artists to doxxed founders, our guide on how to invest in NFTs will explain all you need to get started.

Next, a good investment is all about being in the right place at the right time. While digital assets are often cheapest at a project’s launch, sometimes the floor price will drop post-reveal. To learn more about choosing your timing, you’ll need to read over when to buy NFTs!

Beyond that, there are a few hoops to jump through to get the best NFTs. Most projects have an allowlist or whitelist. Basically, these act as gated mints, access to which you may have to compete for or earn. For tips about allowlists, premints and more, make sure you study the criteria on how to get NFT whitelisted.

Beware of gas fees and gas wars

Before buying NFTs, you should be aware of Crypto gas fees. In a nutshell, you must pay miners gas fees or transaction fees to carry out each and every transaction on the blockchain. Yes, every single action you make on the blockchain costs money! As daunting as that may sound, you’ll find it easy with our full-length guide about NFT Gas Fees .

Next, if you’re vying for tokens on Ethereum, you must consider gas wars. These occur when the transaction fees are extremely high due to network congestion. If you don’t want to get caught in the ruckus, make sure to read our guide on how to escape NFT gas wars.

NFT Smart Contracts 101

Non-fungible tokens are all based on smart contracts. Put simply, a smart contract is a digital contract written in code and stored on the blockchain. They are automatically executed upon meeting certain pre-established conditions. In a smart contract, you can find everything from ownership and transaction details to custom trading rules and special rights. To learn more in-depth about what that means follow our crash course on what a smart contract is. 

Beyond that, reading smart contracts is a skill that not many (but more should) have. If you want to get ahead, a great place to start is Etherscan. To explain, Etherscan is a “block explorer”. Essentially it allows you to read and interact with smart contracts on Ethereum. Following this simple guide, you can learn how to use Etherscan too.

Once you have the confidence reading smart contracts, it’s time to start interacting with them. Here we have a guide to teach you how to mint an NFT from the smart contract.

NFT storage

While smart contracts are stored on the blockchain, the actual files included may not be. While some store the image files on-chain, like CryptoPunks and CryptoSkulls, others use decentralized hosting services like IPFS or Arweave. Still confused? Check out our guide on NFT storage to learn more!


So, what the hell is a DAO? Well, by definition it is a ‘Decentralised Autonomous Organisation. In short, its a structure that allows holders to vote and decide on proposals completely autonomously. In web3, NFT and crypto projects use these to decide what happens with treasury money or a shared asset. To learn more, read our guide on what a DAO is. If you’re feeling confident, you can even make your own with our how to create a DAO guide.


We have covered everything you’d need to kick start your Non-fungible journey. However, remember— don’t make any hasty decisions due to FOMO. At the end of the day, NFTs, like crypto, are volatile assets with considerable market risks. There is no guarantee of profits. Besides, with the rising NFT scams, you may even end up losing all your assets. 

Therefore, always do your own research before making any investment decisions. If you do decide to go down the non-fungible token road, we hope you get to be part of some incredible communities.
