Overview
The mempool is the pool of pending transactions waiting to be included in a block. It is where transactions wait before confirmation. The mempool is the arena for MEV extraction.
How It Works
Broadcast transactions enter the mempool, where they are visible to validators and bots. Validators select transactions to include based on fees. The mempool's transparency enables front-running and MEV.
Why It Matters
The mempool determines transaction ordering and is central to MEV dynamics. It affects user costs and fairness. Private mempools and order-flow auctions aim to reduce harmful MEV.
