I am currently using eth_sendRawTransaction to submit transactions to the public mempool using an Infura node and looking into flashbots/mev-boost to prevent my users from potential frontrunning. Unlike broadcasting a transaction which lands on-chain even if the transaction fails, troubleshooting Flashbots bundles is considerably more challenging, since any of the following circumstances will prevent your bundle from landing on chain: This repository contains the FlashbotsBundleProvider ethers. This strategy is particularly relevant to searchers who operate on public mempool transactions, and/or employ strategies that leave leftover MEV on the table (for example, if your strategy changes 原文标题：《元宇宙之道丨一文了解 Flashbots 最新重大版本升级，引入超级捆绑概念（mega bundles）》 撰文：Robert Miller，Flashbots 产品经理 以太坊 MEV 市场解决方案 Flashbots 今日正式发布了 v0.
