General Web3 Glossary
Understanding the foundational concepts of Web3 is the first step toward fluency in the space. These terms apply broadly across decentralized technologies.
Airdrop
An airdrop occurs when a project distributes free tokens or NFTs directly to users' wallets. This can serve as marketing, a reward for early supporters, or a way to distribute assets after a fiat-based sale where wallet details weren’t initially collected.
DAO (Decentralized Autonomous Organization)
A DAO is a community-driven organization governed by smart contracts and member voting. There’s no central leadership—decisions are made collectively. For example, ConstitutionDAO famously attempted to purchase an original copy of the U.S. Constitution through crowd-funded efforts.
dApp (Decentralized Application)
A dApp runs on a blockchain network rather than a centralized server. Because data is distributed and secured via cryptography, users retain control over their information as long as they safeguard their private keys.
DeFi (Decentralized Finance)
DeFi refers to financial services built on blockchain technology without intermediaries like banks. These include lending, borrowing, trading, and yield farming—all powered by smart contracts. Play-to-earn games are a popular application of DeFi principles.
Doxing / Doxxing
Short for “dropping documents,” this term describes the act of revealing someone’s private personal information online—often maliciously.
Fairdrop
Unlike standard airdrops that give equal amounts to eligible users, fairdrops distribute tokens proportionally based on a user’s holdings at a specific blockchain snapshot.
GameFi (Game Finance)
GameFi blends gaming with financial incentives. Players earn crypto tokens or NFTs through gameplay, which can later be traded for real-world value—commonly seen in play-to-earn models.
IRL (In Real Life)
Used to distinguish physical reality from digital or virtual experiences. Synonymous with “meatspace.”
IYKYK (If You Know, You Know)
A subtle nod to insider knowledge. This phrase signals that only those familiar with a particular community or trend will understand the reference.
Meatspace
Another term for the physical world, contrasting with virtual environments like metaverses or online platforms.
Noob
A newcomer or beginner in a crypto or NFT community. The opposite of an OG.
OG (Original Gangster)
Refers to early adopters who joined a project before it gained popularity. OGs are often respected within communities for their foresight and loyalty.
P2E (Play-to-Earn)
A model where players earn cryptocurrency or NFTs by participating in games. These earnings can be converted into real money, creating new economic opportunities in digital worlds.
Shill
To actively promote a project—often on social media—either out of genuine belief or to gain benefits like whitelist access or price appreciation.
Smart Contract
Self-executing code on a blockchain that triggers actions when predefined conditions are met. With no intermediaries involved, smart contracts ensure transparency and trustlessness.
Snapshot
A record of user balances at a specific block height. Projects use snapshots to determine eligibility for airdrops or fairdrops.
Essential Crypto Slang
Now that we’ve covered the basics, let’s dive into the colorful slang used daily in crypto communities.
Ape / Ape In
To go “all in” on a risky investment. Originating from the meme “apes together strong,” it reflects collective confidence despite high risk.
ATH (All-Time High)
The highest price an asset has ever reached. Reaching ATH is often celebrated in bull markets.
BTD (Buy the Dips)
Encourages investors to purchase assets during price declines, based on long-term conviction.
DD (Due Diligence)
The research process before investing. Doing your DD helps avoid scams and poor decisions.
Degen (Degenerate)
A playful yet critical term for someone who invests recklessly without proper research—often chasing quick gains through pump-and-dump schemes.
Diamond Hands
Describes holders who refuse to sell even during steep price drops. Symbolizes resilience and strong belief in an asset’s future.
DYOR (Do Your Own Research)
A reminder that no advice should be taken at face value. Always verify claims independently before investing.
FOMO (Fear of Missing Out)
The anxiety that drives impulsive buying when prices rise rapidly or hype builds around new projects.
FUD (Fear, Uncertainty, and Doubt)
Negative narratives spread—often anonymously—to manipulate market sentiment and drive prices down.
GMI / WAGMI (Gonna Make It / We All Gonna Make It)
Motivational phrases used during downturns to maintain morale. The opposite, NGMI (“Not Gonna Make It”), is self-deprecating humor after a bad trade.
HODL (Hold On for Dear Life)
A misspelling of “hold” from a 2013 Bitcoin forum post, now iconic in crypto culture. It means refusing to sell despite volatility.
LFG (Let’s F*** Go)
An energetic cheer used to hype up community excitement—especially before major launches or rallies.
NFA (Not Financial Advice)
A disclaimer used when sharing opinions to avoid liability. Always pair with DYOR.
Paper Hands
The opposite of diamond hands—someone who sells at the first sign of trouble due to fear or panic.
Ponzi Scheme
A fraudulent investment model where returns are paid from new investors’ funds rather than actual profits. Some critics compare certain meme coins or GameFi projects to Ponzi dynamics.
Pump and Dump
A manipulative tactic where insiders inflate an asset’s price through false hype, then sell off their holdings—crashing the price and harming latecomers.
REKT
Short for “wrecked.” Used humorously to describe severe financial losses in trading or investing.
Rug Pull
When developers abandon a project and disappear with investors’ funds—a devastating form of scam common in low-trust ecosystems.
To the Moon
An expression of extreme optimism about an asset’s price trajectory—implying it will skyrocket.
Whale
An individual or entity holding large amounts of cryptocurrency. Whale activity can significantly influence market movements.
NFT-Specific Terms You Need to Know
NFTs have their own subculture and terminology—especially around collecting, utility, and community engagement.
AMA (Ask Me Anything)
Live sessions hosted by NFT teams on Discord or Twitter Spaces where holders can ask questions directly.
Burn
Destroying an NFT by sending it to an inaccessible wallet address (“burn address”). Projects may do this to reduce supply and increase scarcity.
Flip
Buying NFTs at low prices and reselling quickly for profit—common during early phases of hyped collections.
Floor Price
The lowest current listing price in an NFT collection. A rising floor often indicates growing demand.

Private trading venues for large orders without public visibility—minimizing market impact.
DEX (Decentralized Exchange)
Peer-to-peer trading platforms built on blockchain (e.g., Uniswap). Users retain custody of funds at all times.
