DeFi use cases involve a wide range of applications that aim to replicate traditional financial services without intermediaries. Common DeFi use cases include decentralized exchanges (DEXs), lending and borrowing platforms, yield farming, and synthetic assets. DeFi also offers stablecoins, insurance, and staking protocols, allowing users to earn rewards while maintaining control over their assets. By enabling peer-to-peer transactions, DeFi reduces fees, enhances financial inclusion, and offers greater transparency, revolutionizing the traditional financial landscape through blockchain technology.
