Compound Finance
Compound Finance is a decentralized finance (DeFi) protocol built on the Ethereum blockchain that enables users to lend and borrow cryptocurrencies algorithmically through smart contracts. It uses interest rate models based on supply and demand to automatically set borrowing rates, allowing lenders to earn interest on their assets and borrowers to access liquidity without intermediaries. The protocol issues cTokens as interest-bearing tokens that represent a user's share in a lending pool.
Developers should learn Compound Finance to build DeFi applications that integrate lending and borrowing functionality, such as yield farming strategies, liquidity management tools, or cross-protocol integrations. It's particularly useful for projects requiring automated interest rate mechanisms, composable financial services, or exposure to decentralized money markets on Ethereum and other EVM-compatible chains.
