Collateral Liquidations
Collateral liquidations are the automated processes within smart contracts that sell a borrower's assets when their collateral-to-debt ratio falls below a certain threshold. In decentralized finance, this is a rigid, code-based response to price volatility designed to protect the solvency of the protocol.
Because these liquidations are automated, they can occur in massive volumes within seconds, significantly impacting market prices. If many borrowers are liquidated at once, it can trigger a cascade that threatens the stability of the entire protocol.
This mechanism is the primary defense against bad debt but also a major source of flash crashes. Understanding the parameters and trigger points of these liquidations is vital for managing risk in DeFi environments.
