# Overview ### Overview The **MEV Zone Block Builder** performs a critical role in the block production mechanism within a framework designed to optimize for maximal extractable value (MEV). Its core function is to manage transaction bundles submitted by searchers, which are entities that construct these bundles to exploit transaction ordering for specific opportunities, such as arbitrage or liquidations. The block builder evaluates the received bundles based on their associated bids, with priority assigned to those offering higher bids, as these maximize the potential rewards for validators. After determining the order of bundles by profitability, the block builder assembles a candidate block. This block includes the highest-ranking bundles alongside standard transactions sourced from the mempool, thereby integrating both MEV-driven and general transaction activity. Once the candidate block is constructed, it is transmitted to validators, who assess the proposed blocks and select the one with the highest cumulative reward. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
