Your quick and practical guide for all NFT-related definitions


Address | The identification of a sender or receiver of a cryptocurrency transaction on the blockchain. Addresses are derived from private and public keys of a user. For example, "0xb794f5ea0ba39494ce839613fffba74279579268" is an address on Ethereum.
Airdrop | An event where certain users will receive free tokens for holding onto certain types of assets for a moment of time. Often a surprise and unknown to users.


Bear Market | A bear market is one that is in decline having fallen 20% or more from recent highs.
Blockchain | The Blockchain is often defined as an online ledger where everyone has access to records and transactions. It is transparent and immutable.
Bookkeeping | Term used to describe the action of keeping records of financial affairs within a business.

Collectible | Assets or items that will have value because of their rarity. Most collectible projects have a limit of items available. For example, there are only 10,000 Bored Apes NFTs.
Cryptocurrency | A type of digital currency that is stored on the Blockchain, such as Bitcoin, or Ether.
CryptoPunks | A non-fungible token collection on the Ethereum blockchain launched in June 2017 by the Larva Labs studio. Often criticized because it does not use the ERC-721 standard.


DAO | An acronym that stands for "Decentralized Autonomous Organization", which represents an organization where rules are encoded as a computer program which is transparent, controlled by all of the organization members and not influenced by a central authority or government.
dApps | Short for "Decentralized applications", meaning applications that run on decentralized networks.

DeFi | An acronym for "Decentralized Finance", where the need for intermediaries (banks, brokers, exchanges) is eliminated by using blockchains and smart contracts.
Digital signature | A string of data a user produces using his private key so that anyone who has the corresponding public key, the signature, and the document can verify that the transaction was "signed" by the owner of that particular private key, and it was not changed after it was signed.
Distributed network | A distributed computing network system where data depends on multiple sources and is stored on distributed locations across the network, increasing its safety.
Down the rabbit hole
| A metaphor used to describe something that transports you into a wonderful and surreal world. This expression is used in the crypto art community when curiosity leads you to fall down the rabbit hole of crypto, NFTs, blockchain, DAOs and Web 3, a world that feels surrealist because users and creators are empowered. This expression originates from the movie "Alice in Wonderland", adapted by Walt Disney Studios.


ENS | ENS stands for "Ethereum Name Service", a platform that allows you to name your wallet address differently than "0x........................................", making it easier and more accessible to transact in crypto with other people.
Etherscan | Etherscan is an Ethereum blockchain explorer and analytics platform that tracks when gas is at its lowest. It allows you to review details of the Ethereum block such as prices, addresses, tokens, transaction details and other information.
ERC-1155 | is a novel Ethereum standard that stands for “Ethereum Request for Comments 1155”. It allows efficient transfers between a fungible and non-fungible token within a single transaction.
ERC-20 | is an Ethereum standard that stands for “Ethereum Request for Comments 20”. It is a set of rules that all Ethereum-based tokens must follow used for token implementation on all smart contracts in the blockchain. It is essentially a standard for fungible tokens.
ERC-721 | is an Ethereum standard that stands for “Ethereum Request for Comments 721”. It introduced an open standard interface for NFTs on the Ethereum blockchain. What this implied is that this type of token was meant to be unique, and capable of having a different value than other tokens (contrarily to fungible tokens, such as Bitcoin).

Fiat | A term used to refer to regular currencies like CAD, USD, Euro.
Fungible | A term used to describe assets that are interchangeable by another item of identical value. For example, money is an interchangeable asset since it is possible to make an exchange between two currencies as they hold the same value.


Gas | An amount of cryptocurrency required to perform any transaction on the Blockchain. On the Blockchain, every action, such as buying an asset or transferring cryptocurrencies includes fees, which we call gas, to pay for the energy that must be deployed to operate the transaction.
Gas Fee | A payment that an individual has to make in order to complete a transaction on the blockchain and it is used to compensate for the computing power used to verify blockchain transactions.
Gas Tracker | A service showing the most affordable times to transact. Tip: Look for gas tracker to go below 100.
GM / GN | Greeting acronyms standing for "good morning" and "good night". Used by members of the community to greet each other, spreading positivity and communication within social media platforms.


Listing | The action of making an NFT available to the public for purchase.
IPFS | IPFS stands for "InterPlanetary File System", a distributed system for storing and accessing files, websites, applications, and data. IPFS can be used to store data related to NFTs, such as the link to where they were minted.

Minting | The creation process of an NFT, i.e. uploading it onto the platform where it will be sold or offered.
Listing | The action of making a NFT available to the public for purchase.


Mainnet | Short for "main network," this is the principal public Ethereum blockchain. It is also known as "layer 1" when discussing scaling solutions.
Metadata | Data that describes relevant information about other data. Within the NFT space, it provides the NFT’s essential properties, details and anything its creator feels relevant to know.
Metaverse | A network of virtual worlds focused on social connection, where interactions are facilitated by the use of virtual and augmented reality technologies.
