CoinWorld News reports that Polygon has announced the launch of Private Mempool, which provides users with MEV (Maximum Extractable Value) protection through a private transaction submission endpoint. Currently, public mempools make pending transactions visible to all observers, making them vulnerable to frontrunning and sandwich attacks by bots, leading to slippage, transaction failures, or abnormal rollbacks. Private Mempool routes transactions directly to block producers elected by validators, bypassing the public mempool, thereby structurally avoiding exposure and manipulation risks.
