Programmable Collateral Fragility

Collateral

Programmable collateral fragility denotes the heightened susceptibility of collateral pools within decentralized finance (DeFi) to cascading liquidations triggered by smart contract interactions and automated risk management protocols. This fragility arises from the composability of DeFi, where collateral posted in one protocol can be utilized across multiple applications, creating complex interdependencies. Consequently, a localized shock—such as an oracle failure or flash loan exploit—can propagate rapidly through the system, diminishing the value of collateral and initiating a sequence of forced sales.
