Ex-Post Auction

Definition ∞ An ex-post auction is a mechanism where the final price and allocation of trades are determined after all bids and offers have been submitted within a specified trading period. This differs from continuous trading by collecting all orders first and then calculating a single clearing price for the entire block of transactions. It is often used to reduce price manipulation and front-running in financial markets. This system promotes fairness and price stability.
Context ∞ The current situation for ex-post auctions in digital asset markets involves their application in mitigating issues like Maximal Extractable Value (MEV) and improving transaction fairness. A key discussion centers on optimizing the auction design to prevent information leakage and ensure efficient price discovery. Future developments will likely focus on integrating ex-post auction mechanisms into decentralized exchanges and various MEV mitigation strategies.
