DeFi (Decentralized Finance) is a new paradigm in finance that utilizes blockchain technology to create an open and decentralized financial system, allowing anyone to participate without the need for intermediaries such as banks or financial institutions. By using smart contracts and decentralized platforms, DeFi allows for a wide range of financial services including lending, borrowing, trading, and investing, all executed in a transparent and trustless manner. The DeFi ecosystem is built on a set of decentralized protocols and applications that can be accessed by anyone, anywhere, using only an internet connection and a compatible wallet, enabling greater financial inclusion and accessibility.
