Decentralized finance (DeFi) enables users to engage in a variety of financial applications on blockchain platforms, primarily Ethereum, allowing activities such as lending, borrowing, and trading without intermediaries. DeFi solutions include exchanges, lending platforms, smart contracts, and more, which enhance user accessibility and transaction efficiency while reducing operational costs. Clone scripts for popular DeFi platforms like PancakeSwap, Uniswap, and BakerySwap offer entrepreneurs ready-made solutions to launch their own decentralized exchanges.
