TECHNICAL CONCEPTS

Mempool (Memory Pool)

Definition

The mempool is a waiting area for unconfirmed transactions on a blockchain network. Transactions sit in the mempool until miners or validators include them in a block.

Example

💡 Example

When you submit a transaction, it first goes to the mempool where MEV bots can see it before it's included in a block.

Risks to Consider

⚠️ Risks
  • Front-running
  • Transaction stuck
  • MEV extraction

Common Questions

Why is my transaction stuck in the mempool?

Usually due to low gas fees. Miners prioritize higher-fee transactions, so yours waits until network congestion decreases or you increase the fee.
