DeFi Basics Explained

Discover the world of Decentralized Finance built on blockchain technology

What is DeFi?

DeFi (Decentralized Finance) refers to financial services built on blockchain networks, operating without traditional intermediaries like banks. Using smart contracts, DeFi enables lending, borrowing, trading, and earning interest in a permissionless, transparent way.

Core DeFi Concepts

🔄

Decentralized Exchanges (DEXs)

Trade crypto directly with other users without a middleman. You keep control of your funds.

Examples: Uniswap, SushiSwap, PancakeSwap

💰

Lending & Borrowing

Earn interest by lending your crypto, or borrow against your holdings without selling.

Examples: Aave, Compound, MakerDAO

🌾

Yield Farming

Earn rewards by providing liquidity to DeFi protocols. Higher rewards often mean higher risks.

Examples: Curve, Yearn Finance, Convex

🔒

Staking

Lock up your crypto to support network security and earn passive rewards.

Examples: Lido, Rocket Pool, native staking
