DeFi is an emerging technology that allows people to create financial applications on a decentralized blockchain network. These applications aim to provide financial services that are accessible to everyone, regardless of their location or financial status, without the need for intermediaries such as banks or financial institutions. DeFi enables users to store and transfer value securely, lend and borrow digital assets, trade assets, and participate in decentralized governance of protocols. DeFi is built on decentralized blockchain networks such as Ethereum, and its applications are powered by smart contracts that execute transactions automatically and transparently.
