Solver-based auctions are a sophisticated mechanism used in decentralized finance to optimize transaction execution and mitigate Maximal Extractable Value (MEV) extraction. In this model, users submit their orders to a network of specialized entities called “solvers” rather than directly to the public mempool. Solvers compete to find the most efficient way to bundle and execute these transactions, often by solving complex optimization problems to minimize slippage and gas costs.
Optimization
The core function of the solver mechanism is to optimize the execution of multiple orders simultaneously, ensuring fair pricing and preventing front-running. Solvers utilize advanced algorithms to determine the optimal sequence and price for a batch of transactions, creating a more efficient market outcome than simple first-come, first-served processing. This optimization process benefits users by providing better execution prices and reducing the value extracted by malicious actors.
Protocol
The implementation of solver-based auctions requires a specific protocol design that centralizes order flow for a brief period before execution. This design shifts the competition from front-running in the public mempool to a private competition among solvers, where the winning solver is rewarded for providing the best execution for users. This approach enhances market integrity and provides a more robust framework for derivatives trading in a decentralized environment.
