DeFi platforms are decentralized finance solutions built on blockchain technology that allows users to perform financial transactions without intermediaries like banks. These platforms include decentralized exchanges (DEXs), lending platforms, and yield farming protocols. DeFi platforms utilize smart contracts to enable peer-to-peer transactions, automate financial processes, and enhance transparency. Popular DeFi platforms such as Aave, Uniswap, and MakerDAO provide users access to decentralized services that are more accessible,and secure, and often offer better returns compared to traditional finance systems.
