Definition
Decentralized Finance (DeFi) encompasses financial services — lending, borrowing, trading, insurance, derivatives — built on blockchain technology without traditional intermediaries. Smart contracts replace banks, brokers, and exchanges.
Key DeFi protocols include: Uniswap (decentralized exchange), Aave (lending/borrowing), MakerDAO (stablecoin), Lido (liquid staking), and Curve (stablecoin trading). These protocols collectively manage billions in assets and process millions of transactions.
DeFi offers advantages over traditional finance: 24/7 operation, global accessibility, transparency (all code is open), composability (protocols can be combined), and permissionless access (no credit checks or KYC for basic operations).
Why It Matters for Founders
DeFi represents the potential future of financial infrastructure. It demonstrates that complex financial services can operate without centralized intermediaries, potentially reducing costs and increasing access globally.
For founders, DeFi provides building blocks for financial products. Understanding DeFi primitives (lending, AMMs, stablecoins) is valuable whether building in Web3 or traditional fintech, as these concepts increasingly influence mainstream finance.

Real-World Example
Using Aave, a user deposits $10,000 in USDC as collateral and borrows $7,000 in ETH — all without a bank, credit check, or human approval. Smart contracts handle everything.
