Decentralized Finance, commonly known as DeFi, is revolutionizing the traditional financial system by removing intermediaries like banks and enabling peer-to-peer financial transactions on the blockchain.

Built primarily on platforms like Ethereum, DeFi allows users to lend, borrow, trade, and earn interest without relying on centralized institutions.
