Blocky saysFlashbots and private mempools route transactions around the public MEV free-for-all.
To reduce MEV harm, Flashbots created a private channel where searchers submit transaction bundles directly to block builders, and tools like MEV-Boost separate block building from proposing. Users can send transactions through private mempools/RPCs so bots can't see and sandwich them. It doesn't eliminate MEV but makes it more orderly and gives users protection options.
