# On-Chain Liquidations ⎊ Area ⎊ Greeks.live --- ## What is the Mechanism of On-Chain Liquidations? On-chain liquidations refer to the automated process within decentralized finance (DeFi) protocols where a borrower's collateral is sold to repay their loan when its value falls below a predetermined threshold. This mechanism is executed by smart contracts, often triggered by liquidators who monitor collateralization ratios and profit from the liquidation fee. It ensures the solvency of lending protocols by preventing undercollateralized loans. The process is transparent and permissionless, operating without human intervention. ## What is the Trigger of On-Chain Liquidations? The primary trigger for on-chain liquidations is a significant decline in the market value of the collateralized asset, causing the loan-to-value (LTV) ratio to exceed a predefined limit. This threshold is continuously monitored by the protocol and external liquidators. Oracle price feeds play a critical role in accurately determining the collateral's value, making oracle integrity paramount. Rapid price movements, particularly in volatile crypto markets, can quickly push positions towards these triggers. Understanding these triggers is vital for borrowers and lenders. ## What is the Consequence of On-Chain Liquidations? The consequences of on-chain liquidations are significant for both individual participants and the broader DeFi ecosystem. For borrowers, it results in the loss of their collateral, often at a discount, to cover the outstanding debt. For the market, large-scale liquidations can exacerbate downward price pressure, creating a feedback loop that triggers further liquidations. This can lead to systemic instability during periods of market stress. Effective risk management for borrowers involves maintaining sufficient collateral buffers. For protocols, robust liquidation mechanisms are crucial for maintaining solvency. --- ## [Flash Loan Liquidations](https://term.greeks.live/definition/flash-loan-liquidations/) The use of instant, uncollateralized loans to execute liquidations within a single blockchain transaction block. ⎊ Definition ##
