How Does a DeFi App Work?

DeFi apps facilitate financial transactions on decentralized networks through smart contracts, blockchain technology, and automated execution of financial agreements.

Here's the process flow:

• Users interact with the application through a user-friendly interface to perform operations like lending, borrowing, trading, or staking
• Smart contracts automatically execute transactions, which are then verified by network nodes and recorded on the blockchain
• Digital assets such as cryptocurrencies and stablecoins facilitate quick, low-cost transactions
• Immutability ensures transaction integrity throughout the process, while decentralization optimizes accessibility
