Lending Protocol Risk

Definition ∞ Lending protocol risk encompasses the various dangers associated with decentralized lending platforms within the DeFi ecosystem. These risks include smart contract vulnerabilities, which can lead to asset loss, and liquidation risks from volatile collateral. Additionally, oracle manipulation and governance attacks pose threats to the stability and security of these protocols. Managing these risks is paramount for platform integrity.
Context ∞ Lending protocol risk is a persistent concern in the DeFi space, often highlighted in news reports concerning platform exploits or significant market downturns. Developers and auditors continuously work to enhance smart contract security and refine risk models. The industry is exploring decentralized insurance solutions to provide additional layers of protection for users.
