DeFi Basics

DeFi (Decentralised Finance)

DeFi is an umbrella term for financial services — lending, borrowing, trading, and earning yield — that run on public blockchains without banks or intermediaries.

Smart Contract

A smart contract is a program stored on a blockchain that automatically executes predefined actions when specific conditions are met — no human intermediary required.

Blockchain

A blockchain is a distributed database that records transactions in chronological blocks, linked cryptographically, making the history tamper-proof and publicly verifiable.

Stablecoin

A stablecoin is a cryptocurrency designed to maintain a stable value, typically pegged 1:1 to the US dollar, making it ideal for DeFi yield strategies without price volatility risk.

Crypto Wallet

A crypto wallet is software (or hardware) that stores your private keys and allows you to send, receive, and interact with blockchain applications.

Gas Fees

Gas fees are small transaction costs paid to blockchain validators for processing and confirming your transactions on-chain.

DeFi vs CeFi

DeFi (Decentralised Finance) uses smart contracts with no central authority; CeFi (Centralised Finance) uses companies as intermediaries — the key difference is who controls your funds.

MetaMask

MetaMask is the most widely used browser extension and mobile crypto wallet for interacting with DeFi protocols on Ethereum, BNB Smart Chain, and other EVM-compatible networks.

Trust Wallet

Trust Wallet is a mobile-first, multi-chain crypto wallet developed by Binance, supporting BNB Smart Chain and hundreds of other blockchains with a built-in DeFi browser.

Whitepaper

A whitepaper is a technical document published by a crypto project that explains its design, technology, tokenomics, and goals — the foundational reference for evaluating a protocol.

KYC (Know Your Customer)

KYC (Know Your Customer) is the identity verification process required by regulated financial institutions — DeFi protocols typically do not require KYC, allowing permissionless access.

Web3

Web3 is the vision of a decentralised internet built on blockchains, where users own their data and digital assets rather than corporations owning them.

Yield & Returns

Yield Farming

Yield farming is the practice of deploying crypto assets into DeFi protocols to earn returns — through trading fees, interest, or token rewards.

APY (Annual Percentage Yield)

APY is the annualised return on an investment, accounting for compounding — the effect of earning returns on previously earned returns.

Liquidity Pool

A liquidity pool is a smart contract holding two or more tokens that enables decentralised trading — liquidity providers deposit tokens and earn a share of trading fees.

Impermanent Loss

Impermanent loss is the temporary reduction in value experienced by liquidity providers when the price ratio of their deposited tokens changes relative to simply holding them.

TVL (Total Value Locked)

TVL (Total Value Locked) is the total dollar value of assets currently deposited in a DeFi protocol — a key metric for measuring protocol size and adoption.

Fixed Yield

Fixed yield in DeFi means earning a predetermined, guaranteed return on your deposit for a set period — unlike variable APY which fluctuates based on market conditions.

APR (Annual Percentage Rate)

APR (Annual Percentage Rate) is the simple annual return on an investment without accounting for compounding — the base rate before reinvestment effects.

Staking

Staking is the process of locking cryptocurrency to support a blockchain's consensus mechanism (Proof of Stake) in exchange for earning staking rewards.

Compound Interest

Compound interest is the process of earning returns on both your principal and previously accumulated returns — the 'interest on interest' effect that accelerates wealth growth over time.

Protocol Mechanics

DEX (Decentralised Exchange)

A DEX (Decentralised Exchange) is a trading platform that operates via smart contracts, allowing users to swap tokens directly from their wallets without a centralised intermediary.

AMM (Automated Market Maker)

An AMM (Automated Market Maker) is a type of DEX protocol that uses a mathematical formula to price tokens and execute trades automatically, without order books or human market makers.

PancakeSwap

PancakeSwap is the largest decentralised exchange (DEX) on BNB Smart Chain, offering token swaps, liquidity provision, and yield farming with billions in daily trading volume.

Lending Protocol

A DeFi lending protocol is a smart contract system that matches lenders (who earn interest) with borrowers (who provide collateral) without a bank intermediary.

Aave

Aave is a decentralised lending protocol where users earn variable interest by supplying assets or borrow against collateral — one of the largest DeFi protocols by TVL.

Flash Loan

A flash loan is an uncollateralised loan in DeFi that must be borrowed and repaid within a single blockchain transaction — if not repaid, the entire transaction is reversed.

DeFi Governance

DeFi governance is the process by which token holders vote on protocol changes — fee adjustments, new features, treasury spending — through on-chain proposals.

DAO (Decentralised Autonomous Organisation)

A DAO (Decentralised Autonomous Organisation) is an organisation governed by smart contracts and token holder votes rather than a traditional management hierarchy.

DeFi Aggregator

A DeFi aggregator is a platform that searches multiple protocols to find the best yield rates or swap prices, routing your funds automatically to maximise returns.

Slippage

Slippage is the difference between the expected price of a trade and the price at which it actually executes — caused by price movement between order submission and execution.

Security & Safety

Smart Contract Audit

A smart contract audit is an independent security review of a DeFi protocol's code, conducted by specialised firms to identify vulnerabilities before they can be exploited.

Renounced Contract

A renounced contract is a smart contract where the original deployer has permanently transferred ownership to the zero address, meaning no one can ever modify or upgrade the contract.

Rug Pull

A rug pull is a DeFi scam where developers drain a protocol's liquidity or funds and disappear, leaving investors with worthless tokens or empty contracts.

Locked Liquidity

Locked liquidity means the LP (liquidity provider) tokens representing a protocol's liquidity are held in a time-locked smart contract, preventing anyone from removing that liquidity.

DeFi Security

DeFi security encompasses the technical and operational safeguards that protect users' funds in decentralised finance protocols — from smart contract audits to wallet best practices.

Private Key

A private key is a secret cryptographic number that gives complete control over a crypto wallet — whoever holds the private key controls all assets in that wallet.

Price Oracle

A price oracle is a service that provides real-world price data to smart contracts — essential for lending protocols, derivatives, and any DeFi application that needs accurate asset prices.

DeFi Risks

DeFi risks encompass smart contract vulnerabilities, protocol exploits, impermanent loss, regulatory uncertainty, and user error — understanding these is essential before participating in DeFi.

DeFi Insurance

DeFi insurance provides coverage against smart contract exploits, protocol hacks, and other DeFi-specific risks — allowing users to protect their deposits against technical failures.
