Lending Protocol

Definition ∞ A lending protocol is a decentralized application that facilitates the borrowing and lending of digital assets without intermediaries. Users can deposit their crypto assets to earn interest as lenders, or use their existing assets as collateral to borrow other assets. These protocols operate on smart contracts, automating loan origination, interest calculation, and collateral management. They are a cornerstone of decentralized finance, promoting capital fluidity and yield opportunities.
Context ∞ Lending protocols are currently undergoing significant scrutiny regarding their risk management practices and the potential for contagion during periods of market stress. Discussions revolve around the robustness of collateralization models, the management of liquidations, and the transparency of interest rate mechanisms. Ongoing developments focus on enhancing user protection and ensuring the long-term stability of these critical DeFi components.
