What Are Private Mempools and How Do They Shield Transactions?

A private mempool is a dedicated, non-public channel for submitting transactions that bypasses the standard, transparent public mempool. When a trader uses a private mempool, their transaction is sent directly to a trusted party, like a searcher or block builder, who guarantees its inclusion in a block without revealing it to other public bots.

This shields the transaction details from front-running bots, preventing them from creating a preemptive or sandwich trade.
