Terms & Concepts
  • Private Mempool: A transaction routing system that avoids the public mempool, aiming to reduce exposure to front-running and other exploitative trading strategies before execution.
  • Front-running: A practice where someone uses knowledge of a pending transaction to place their own trade first and potentially profit from the expected market move.
  • Sandwich attacks: A tactic where an attacker places one transaction before and one after a victim’s trade to extract value from the victim’s execution.
