Flashbots is a tool to prevent Ethereum MEV issues by enabling private, efficient transactions.

Flashbots is a research and development organization focused on addressing the Maximum Extractable Value (MEV) problem on the Ethereum blockchain. MEV refers to the profit miners can make by reordering transactions within blocks. Flashbots provides tools that allow users to submit transactions directly to miners, bypassing the public mempool. This reduces the risk of front-running and other MEV-related issues. By promoting transparency and efficiency, Flashbots aims to create a fairer transaction environment. It benefits both users and miners by optimizing transaction ordering and execution.
