Decentralized Finance (DeFi) refers to an ecosystem of financial applications built on blockchain technology, aiming to recreate traditional financial services in an open, permissionless, and decentralized manner. These applications facilitate lending, borrowing, trading, and asset management without central intermediaries, leveraging smart contracts to automate financial agreements.
Context
Crypto news frequently reports on DeFi innovations, including new yield-generating protocols, the total value locked (TVL) in various DeFi platforms, and regulatory efforts to bring these decentralized services under traditional financial oversight. Security breaches and smart contract vulnerabilities remain persistent concerns within the DeFi space.
