Slippage and Market Impact Risks
Slippage and market impact risks occur when the size of a trade causes the execution price to move away from the current market price. In liquidations, selling a large amount of collateral can depress the asset's price, potentially reducing the proceeds of the liquidation.
This can lead to a shortfall where the sale does not fully cover the debt. Protocols must account for this by estimating the depth of the liquidity pool and the potential for slippage.
Strategies to mitigate this include breaking large liquidations into smaller, incremental trades or using decentralized exchange aggregators. Understanding these risks is vital for liquidators and protocol designers to ensure the orderly resolution of under-collateralized positions.
It is a fundamental challenge in managing large-scale financial operations on-chain.
