A
Airdrop
beginnerA distribution of free tokens to wallet addresses, typically used for marketing, community rewards, or governance token distribution.
AMM (Automated Market Maker)
intermediateA decentralized exchange mechanism that uses mathematical formulas and liquidity pools instead of order books to facilitate token swaps.
AMM Curve
advancedThe mathematical function governing how a decentralized exchange prices tokens based on the ratio of assets in a liquidity pool.
APR
beginnerAnnual Percentage Rate — the yearly interest rate earned on deposits or paid on loans, without accounting for compounding effects.
APY
beginnerAnnual Percentage Yield — the effective yearly return accounting for compound interest, always higher than the equivalent APR.
Atomic Swap
advancedA trustless peer-to-peer exchange of cryptocurrencies between different blockchains using hash time-locked contracts without intermediaries.
Automated Market Maker
intermediateA smart contract-based system that uses mathematical formulas to price assets in liquidity pools, enabling decentralized trading without order books.
B
C
Collateralization Ratio
intermediateThe ratio of collateral value to the value of borrowed assets in a DeFi loan, determining safety margin before liquidation.
Composability
intermediateThe ability of DeFi protocols to interact seamlessly with each other, enabling complex financial strategies by stacking protocols like building blocks.
Concentrated Liquidity
advancedA DEX mechanism allowing liquidity providers to allocate capital to specific price ranges rather than the full spectrum, improving capital efficiency.
D
DEX (Decentralized Exchange)
beginnerA cryptocurrency exchange that operates without a central authority, using smart contracts on a blockchain to facilitate peer-to-peer trading.
DEX Aggregator
intermediateA platform that sources liquidity from multiple decentralized exchanges to find the optimal swap route and best execution price for token trades.
F
Flash Loan
advancedAn uncollateralized DeFi loan that must be borrowed and repaid within a single blockchain transaction, enabling zero-capital arbitrage.
Flash Loan Attack
advancedAn exploit that uses uncollateralized flash loans to temporarily manipulate market conditions and drain funds from vulnerable DeFi protocols.
G
I
Impermanent Loss
intermediateThe temporary loss of value experienced by liquidity providers when the price ratio of pooled tokens changes relative to simply holding them.
Impermanent Loss
intermediateThe temporary loss of value experienced by liquidity providers in AMMs when the price ratio of deposited tokens changes compared to simply holding them.
Initial DEX Offering
intermediateA token launch method where a new cryptocurrency is first sold to the public through a decentralized exchange launchpad.
L
Lending Protocol
intermediateA DeFi platform that allows users to lend assets for interest or borrow against collateral, creating decentralized credit markets.
Liquid Staking
intermediateA mechanism that issues derivative tokens representing staked assets, allowing users to earn staking rewards while maintaining liquidity and DeFi composability.
Liquid Staking Token
intermediateA tokenized representation of staked assets that can be freely traded or used in DeFi while the underlying assets remain staked and earning rewards.
Liquidity Mining
intermediateA mechanism where protocols distribute tokens to users who provide liquidity, incentivizing capital deployment and bootstrapping new markets.
Liquidity Pool
intermediateA collection of cryptocurrency tokens locked in a smart contract that provides liquidity for decentralized trading, enabling AMMs to facilitate swaps without traditional order books.
Liquidity Provider
intermediateA user who deposits assets into a DeFi protocol pool, earning trading fees and potentially token rewards in exchange for supplying market liquidity.
M
Maximal Extractable Value
advancedThe profit that can be extracted from block production beyond standard rewards, by strategically ordering, including, or censoring transactions.
MEV (Maximal Extractable Value)
advancedThe profit validators or searchers can extract by reordering, inserting, or censoring transactions within a block, exploiting DeFi arbitrage and front-running opportunities.
MEV Protection
advancedTechniques and tools that shield DeFi transactions from being exploited by MEV bots through front-running, back-running, or sandwich attacks.
O
P
Perpetual DEX
advancedA decentralized exchange that offers perpetual futures trading on-chain, combining the leverage of derivatives with the self-custody of DeFi.
Protocol Revenue
intermediateThe fees earned by a DeFi protocol from its users, representing the actual cash flow generated by the smart contract system.
R
Restaking
advancedA DeFi mechanism that allows staked assets to simultaneously secure multiple networks or services, earning additional yield on the same capital.
Rug Pull
beginnerA scam where project developers drain liquidity or abandon a project after collecting user funds, leaving token holders with worthless assets.
S
Sandwich Attack
advancedA form of MEV extraction where an attacker front-runs and back-runs a pending DEX transaction, profiting from the price impact at the victim's expense.
Slashing
intermediateA punitive mechanism in Proof-of-Stake networks that destroys a portion of a validator's staked tokens for malicious behavior or extended downtime.
Smart Contract Audit
intermediateA professional security review of a smart contract's code to identify vulnerabilities, logic errors, and attack vectors before deployment.
Stablecoin
beginnerA cryptocurrency designed to maintain a stable value relative to a reference asset, typically the US dollar, through various backing and stabilization mechanisms.
Staking
beginnerThe process of locking up cryptocurrency to support a proof-of-stake blockchain network, earning rewards in return for helping validate transactions.
T
Timelock
intermediateA smart contract mechanism that enforces a mandatory waiting period before certain actions can be executed, providing security against sudden malicious changes.
Token Unlock
intermediateA scheduled event where previously locked or vesting tokens become freely tradeable, often creating sell pressure as early investors and teams realize gains.
Total Value Locked
beginnerThe aggregate dollar value of assets deposited into a DeFi protocol, measuring its adoption, trust, and capital attraction.
TVL (Total Value Locked)
beginnerThe total amount of cryptocurrency deposited in a DeFi protocol's smart contracts, used as a primary metric for measuring protocol adoption and health.
TVL Ratio
intermediateThe ratio of a DeFi protocol's revenue to its Total Value Locked, measuring how efficiently the protocol monetizes its deposited capital.
V
Vault
intermediateAn automated smart contract strategy that deposits, compounds, and manages user funds to optimize yield across DeFi protocols.
Vote-Escrowed Tokenomics
advancedA token model where holders lock tokens for extended periods to earn voting rights and boosted rewards, aligning long-term incentives and reducing sell pressure.
W
Y
Yield Aggregator
intermediateA DeFi platform that automatically moves user funds between protocols to maximize yield by finding and switching to the best available rates.
Yield Farming
intermediateA DeFi strategy of deploying crypto assets across protocols to maximize returns through lending, liquidity provision, and staking reward optimization.
