Front-running liquidation is a specific form of front-running where an actor observes a pending liquidation transaction on a blockchain and executes a new transaction to perform the liquidation first. This attack exploits the public nature of the mempool, where pending transactions are visible before being confirmed on-chain. The front-runner identifies a profitable liquidation opportunity and pays a higher gas fee to ensure their transaction is processed before the original liquidation attempt. This practice allows the front-runner to capture the liquidation bonus or fee associated with closing the position.
Arbitrage
The motivation behind front-running liquidation is pure arbitrage, where the front-runner profits from the difference between the collateral value and the outstanding debt of the liquidated position. The liquidation mechanism typically offers a bonus to the liquidator for successfully closing the position and preventing bad debt. Front-runners compete to capture this bonus by optimizing their transaction fees and execution speed. This activity can lead to increased transaction costs for legitimate liquidators and reduce the efficiency of the liquidation process.
Latency
The risk of front-running liquidation is directly related to transaction latency and the time window between a liquidation trigger and its execution. In high-speed blockchain environments, liquidators must compete fiercely to be the first to execute the transaction. This competition often results in a “gas war,” where liquidators bid up transaction fees to prioritize their transactions. The latency between observing a liquidation opportunity and submitting a front-running transaction is a critical factor in determining the success of this strategy.
