Decentralized Finance (DeFi)

Financial services built on blockchain technology that operate without traditional intermediaries.

Definition

Decentralized Finance (DeFi) refers to financial services and applications built on blockchain networks that operate without traditional intermediaries like banks, brokerages, or exchanges. DeFi protocols use smart contracts to automate lending, borrowing, trading, insurance, and yield generation. Users interact directly with protocols through crypto wallets, maintaining custody of their assets. Major DeFi categories include decentralized exchanges (Uniswap, Curve), lending platforms (Aave, Compound), and yield aggregators (Yearn Finance). Total value locked (TVL) in DeFi has reached tens of billions of dollars. While DeFi offers permissionless access and transparency, risks include smart contract vulnerabilities, impermanent loss, and regulatory uncertainty.
