Mempool Backlog

A mempool backlog occurs when a large number of unconfirmed transactions wait in the network's staging area before being included in a block. This queue is a direct result of network congestion and can be caused by sudden surges in activity, such as a major market event or a popular NFT drop.

For traders, a mempool backlog means their orders are stuck in limbo, preventing them from responding to price changes or managing their positions. This delay can lead to significant financial loss, especially when trying to exit a leveraged position before a liquidation event.

Managing transaction priority via gas fees is the primary way users navigate this backlog, though it creates an environment where only those willing to pay the most can trade.
