Gate News, April 2, Polygon announced the launch of a Private Mempool feature, providing users with MEV (maximum extractable value) protection through private transaction submission endpoints. Currently, the public mempool mechanism makes pending transactions visible to all observers, making them easy targets for robot front-running and sandwich attacks, which can lead to user slippage, failed transactions, or abnormal rollbacks. Private Mempool routes transactions directly to block producers generated through the validator election process, bypassing the public mempool, and structurally avoids the risks of transaction exposure and manipulation.
