Public mempools expose unconfirmed transactions to MEV bots, enabling pre-confirmation exploitation through transaction simulation and strategic submission.

Quotes that support claims

Mempools, whether public or private, serve as holding areas where transactions wait to be picked up by block builders

Pending transactions are held in the network’s publicly visible waiting area called the 'mempool,' where they will sit until a miner or validator selects them

During that window, bots can see every pending, unconfirmed transaction–essentially peering into the future and allowing them to front-run trades
