TL;DR: It has been a great year for Flashbots Protect! Post-merge, all transactions sent to Protect will have frontrunning and revert protection. But due to how mev-boost will be launched at the merge, Flashbots Protect will be down for at least 1 hour after the merge. If you rely on Flashbots Protect as a user or application developer then please plan accordingly.
Today Flashbots and our community are excited to launch a public beta of Flashbots Protect, a new product line focused on allowing everyday users and developers to easily submit transactions to Flashbots.
