Technology platforms enable decentralized finance (DeFi) by utilizing blockchain to create peer-to-peer financial systems without traditional intermediaries like banks. Through smart contracts, users can interact directly with decentralized applications (dApps), executing transactions and agreements autonomously. These platforms offer a range of financial services, from lending and borrowing to trading and earning interest, all powered by cryptocurrency. By reducing reliance on centralized institutions, DeFi promotes financial inclusion and accessibility. Additionally, transparency, security, and programmability in transactions pave the way for innovative financial solutions that empower users.
