What Is Decentralized Finance (DeFi)?

Decentralized Finance, or DeFi, refers to a financial ecosystem built on blockchain technology that eliminates intermediaries like banks and brokers. It leverages smart contracts on blockchain networks, primarily Ethereum, to enable peer-to-peer financial activities. DeFi platforms allow users to lend, borrow, trade, and earn interest on cryptocurrencies without relying on traditional financial institutions. The system is transparent, permissionless, and accessible globally, promoting financial inclusion. By removing centralized control, DeFi reduces costs, increases transaction speed, and empowers users with complete control over their digital assets. Lending and borrowing in DeFi are core functions, allowing users to generate passive income and access liquidity efficiently.

How Lending Works In Decentralized Finance

Lending in DeFi allows users to deposit their cryptocurrency assets into smart contract protocols, which then become available for borrowers. In return for providing liquidity, lenders earn interest on their deposits, often higher than traditional banking interest rates. Platforms like Aave, Compound, and MakerDAO facilitate decentralized lending through automated systems, eliminating the need for credit checks. Lenders can choose different assets and risk levels, with interest rates determined algorithmically based on supply and demand. The funds deposited by lenders are typically over-collateralized, reducing default risks. By participating in DeFi lending, users can generate passive income while contributing to the ecosystem’s liquidity.
