The mempool is the gateway to the blockchain. Before anything can be written on a block, it must first move through the mempool. And this important piece of Web3 is often overlooked.
Since the mempool dictates how every transaction gets written to and confirmed on-chain, understanding the mempool can help you understand what is happening with your in-flight transactions and unlock deep insights into how blockchains work.
