Liquidation Threshold Exploitation

Liquidation threshold exploitation occurs when a trader forces a protocol to liquidate a position by intentionally driving the asset price toward the protocol's defined liquidation point. This is often done by combining large sell orders with oracle manipulation to ensure the protocol perceives the position as under-collateralized.

Once the liquidation is triggered, the attacker may capture the liquidation bonus or seize the collateral at a discount, depending on the protocol's design. This exploit is a direct attack on the solvency mechanisms of lending and derivative protocols.

It turns the safety feature designed to protect the system into a mechanism for value extraction. Protocols attempt to prevent this by setting conservative liquidation thresholds and utilizing robust, multi-source oracle feeds that are resistant to short-term manipulation.

The exploit demonstrates how critical parameter settings are to the overall health and stability of a decentralized financial system. It requires deep knowledge of the specific protocol's risk management math.
