Polygon Launches Private Mempool to Mitigate Risks of Transaction Exposure and Manipulation

Odaily News Polygon has announced the launch of a Private Mempool. It provides users with protection against MEV (Maximal Extractable Value) through a private transaction submission endpoint. The current public mempool mechanism makes pending transactions visible to all observers, making them susceptible to frontrunning and sandwich attacks by bots. This can lead to user slippage, transaction failures, or abnormal reversals. In contrast, the Private Mempool routes transactions directly to block producers elected by validators, bypassing the public mempool, thereby structurally avoiding the risks of transaction exposure and manipulation.
