Pronounced “one of one”, a 1:1 NFT is a unique, single edition NFT, as opposed to an NFT that’s part of a multi-edition collection. For example, Everydays by Beeple is an example of a 1:1 NFT, whereas an NFT from the 1989 Sisters collection is not. 

10k Project

A collection of 10,000 NFTs. 


To send an NFT or NFTs to a wallet free of charge. NFTs can be airdropped for a number of reasons, such as to promote a new collection or reward someone for participating in a contest. 

Airdrops can also be used to lure someone into a scam, such as a rug pull, so be sure to read our articles How to spot and avoid crypto scams and Crypto security basics: Staying safe in Web3 before interacting with an airdropped NFT

Ape In

To heavily invest in a new project, usually out of fear of missing out. 

Avatar Project

Sometimes used interchangeably with terms like PFP and generative art, an avatar project is a collection of cartoon avatar NFTs, usually represented as a portrait depicting the avatar from the shoulders or neck up. CryptoPunks is a popular example of an avatar project. 


Pseudonym for Mike Winkelmann, perhaps the most well known digital artist. Beeple’s Everydays: the First 5000 Days sold for $69,400,000, the current record for most expensive NFT.

Binance Smart Chain

A blockchain compatible with buying and selling NFTs. While Ethereum is the most popular blockchain for NFTs, prominent competitors include Binance and Solana.


To burn an NFT is to effectively destroy it. While technically NFTs always remain on the blockchain, you can remove one from circulation by sending it to a wallet address that can't be accessed. 

Cold Wallet (also called Hardware Wallet)

A cold wallet is a physical device that keeps your crypto assets (e.g., cryptocurrency, NFTs) completely offline. Many such cold wallets look like USB drives.  A cold wallet is much more secure than what is called hot wallet (see below), since it keeps your crypto assets off line.  The disadvantage is the possibility of losing your device and hence the assets that it contains.


A Decentralized Autonomous Organization (DAO) has no central leadership; it's transparent and encoded on the blockchain. As described by Ethereum DAOs are:

Member-owned communities without centralized leadership.

A safe way to collaborate with internet strangers.

A safe place to commit funds to a specific cause.


To remove an NFT from an exchange. Delisting an NFT incurs gas fees. NFT communities often encourage holders to delist NFTs before big announcements.


An instant messaging platform and the go-to place for discussing NFTs.


A token standard that allows for the creation of unique, non-fungible tokens. It differs from ERC-20, for example, which is used to mint fungible tokens.


A blockchain with smart contract functionality. Ethereum is currently the main platform for NFT projects.

Floor Price

The lowest NFT price in a collection. To “buy the floor” or "floor sweep" is to buy the cheapest NFT in a collection.

Floor Sweep

To buy up the cheapest NFTs in a collection. Sweeps can be organized by an NFT collection’s community to raise the project’s floor price.

Fractional Ownership

Partial ownership rights over an NFT. Sellers can sell percentages of a work and buyers can buy what they can afford.


Replaceability. Dollars are fungible because a dollar owed can be paid using any dollar in existence. Something that is non-fungible, like a painting or NFT, is one-of-a-kind.

Gas Fees

Fees that blockchain users pay to compensate for the computational resources used to execute transactions. Gas fees ensure that transactions will be genuine and discourages bad actors from spamming the network with a high volume of transactions.

Generative Art

A project in which NFTs are generated from a pool of limited assets. In a generative art collection, each NFT can have a unique set of traits while still sharing individual traits with other NFTs in the collection. 

InterPlanetary File System

A means of storing NFT data that is considered superior to storing on an HTTP gateway URL, since the latter is tied to a specific provider. IPFS addresses allow users to find a piece of content so long as someone on the network is hosting it.


A public ledger derives its name from the age-old record-keeping system used to record information, such as agricultural commodity prices, news, and analysis. The public ledger was available for general public viewing as well as for verification. As cryptocurrency-based blockchain systems emerged, which rely on a similar record-keeping and public verification mechanism, the use of the public ledger gained popularity in the world of cryptocurrency. This article explores cryptocurrency public ledgers, how they work, and the challenges they face.


The collection of data that defines ownership and differentiates one NFT from another. Metadata can be on-chain or off-chain.


The leading Ethereum wallet used as a gateway to NFT apps like OpenSea, Rarible, and Axie Infinity.


A virtual 3D world where people can interact. Popular blockchain-based metaverses include Decentraland and The Sandbox, virtual gaming worlds where users can buy and sell land NFTs.

Play-to-Earn Game

Games in which players can earn rewards, such as NFTs and cryptocurrency, that have real-world value and can be exchanged outside of gameplay. Axie Infinity is currently the most popular NFT play-to-earn game.


An Ethereum-compatible protocol that provides cheaper, faster, and more secure payment transactions. Polygon is an attractive platform for NFTs because of cheap minting costs and low gas fees.


A community-owned NFT marketplace founded in 2020. The Moscow-based platform mostly hosts digital art, and is fuelled by its native ERC-20 token RARI.


An important measure of an NFT’s value. The overall rarity of an NFT is usually determined by calculating the scarcity of its individual traits, e.g. by averaging them or multiplying them together.


A document that maps out the goals and next steps for an NFT project. 


Money earned by an NFT creator through the token’s resale. Some NFTs automatically pay royalties each time an NFT is sold. An NFT can be hardcoded to pay an artist royalties forever, an interesting use case that has the potential to shake up the music industry.

Rug Pull

Smart Contract

A self-executing digital contract. NFTs are composed of code written in smart contract programming language like Solidity.


A programming language for writing smart contracts. Solidity is a high-level language like Java and Python that is ideal for Ethereum, which hosts most NFTs.


One of the main challengers to Ethereum as a preferred blockchain for NFT marketplaces. Popular Solana marketplaces include Magic Eden, Solanart and Solsea

Utility-focused NFTs

NFTs with real-world use cases. For example, NFTs can be used to improve event ticketing. Digital art can also have utility coded into it. E.g., ownership of a Bored Ape grants members-only benefits like access to a collaborative graffiti board.

Verifiable Provenance

Built-in feature of NFTs, which document their proof of origin on the blockchain. A perk of collecting digital art.


Short for "crypto wallet". A crypto wallet is an interface that lets you interact with your blockchain assets. Crypto assets are essentially data on the blockchain. Crypto wallets contain the private key to their location on that blockchain, and this private key determines whether you can access that crypto.
