DeFi has the potential to assist e-commerce by providing alternative financial services built on blockchain technology. The COVID-19 pandemic led to increased demand for e-commerce as lockdowns reduced in-person retail. DeFi offers decentralized applications that allow users to exchange digital assets without needing traditional financial institutions. While early versions of DeFi had security issues, improvements like smart contract insurance help address vulnerabilities and reduce risks for users. Overall, DeFi illustrates how blockchain technology can transform the global financial system to be more transparent and accessible.
