How Does a ‘Private Transaction Pool’ Attempt to Mitigate MEV?

A Private Transaction Pool, often called a private mempool, allows users to submit their transactions directly to a block builder or validator without first broadcasting them to the public mempool. This prevents 'searchers' and attackers from seeing the transaction and front-running it.

By keeping the order flow private until inclusion in a block, the pool effectively eliminates the information asymmetry that enables MEV attacks like sandwiching.
