Back Running: Following Profitable Transactions

Back running involves placing transactions immediately after profitable transactions to capture secondary opportunities. It's like following successful traders to pick up the crumbs they leave behind.

Back running is a MEV extraction strategy where bots place transactions immediately after profitable transactions to capture residual value or secondary opportunities. This technique exploits the predictable market effects of large transactions.

How Back Running Works

Transaction monitoring tracks pending and confirmed transactions to identify opportunities for profitable follow-up trades.

Immediate execution places back-running transactions in the next available block to capture time-sensitive arbitrage opportunities.

Value extraction profits from predictable price movements, slippage, or market inefficiencies created by the original transaction.

Real-World Examples

  • DEX arbitrage following large swaps that create temporary price differences between trading venues
  • Liquidation following executing additional liquidations after initial liquidation transactions reveal profitable opportunities
  • NFT floor sweeping buying remaining cheap NFTs after someone purchases expensive ones from a collection

Why Beginners Should Care

MEV landscape understanding as back running represents one component of the complex MEV extraction ecosystem.

Market efficiency improvements from back running that helps eliminate temporary price inefficiencies and arbitrage opportunities.

Transaction costs awareness as back running competition can increase gas prices during profitable trading periods.
