## Mempool Transaction Monitoring

Mempool Transaction Monitoring involves watching the queue of pending transactions on a blockchain to anticipate future market activity. Because transactions are public before they are confirmed in a block, sophisticated actors can see what others are doing and adjust their own strategies accordingly.

This visibility is the source of many front-running and sandwich attacks, as it allows attackers to insert their own transactions ahead of others. While it is a natural consequence of the current blockchain architecture, developers are exploring ways to obscure this information through private transaction relays or encrypted mempools.

Monitoring this activity is essential for both protecting users and identifying potential threats in the ecosystem.
