Inter-Protocol Lending Dependency
Inter-protocol lending dependency describes the situation where multiple DeFi protocols rely on the liquidity or assets of each other. For example, a lending protocol might accept tokens that represent a claim on another protocol as collateral.
If the second protocol fails, the value of that collateral vanishes, potentially triggering a default in the first protocol. This creates a complex, interconnected web of risk that is difficult to monitor.
It is similar to the subprime mortgage crisis where the failure of one set of assets caused a collapse in the broader financial system. In crypto, this is often referred to as "contagion risk" within the DeFi ecosystem.
It means that the security of a user's assets is not just dependent on the protocol they are using, but on the health of the entire network of protocols it interacts with. This requires a new approach to risk assessment that looks beyond individual protocols to the entire ecosystem.
