This practice involves identifying and exploiting temporary price discrepancies for the same asset or derivative across different onchain order books or between onchain and offchain venues. Searchers construct specialized transactions designed to execute before standard market orders. The profit is realized by capturing the difference between the price seen by the searcher and the final settled price.
Block
The process is intrinsically linked to the block production mechanism, as searchers compete to have their profitable transaction included in the next block. Bidding mechanisms, often involving sending a higher gas fee or direct payment to the block producer, are used to prioritize inclusion. Control over block ordering is the fundamental lever for this activity.
Transaction
The extraction involves carefully ordering a sequence of operations, often involving a trade, a loan, or a liquidation, within a single atomic unit. This sequencing ensures that the desired outcome is achieved regardless of intermediate market movements. Analyzing the mempool for pending transactions is the initial step in identifying an opportunity.
