  • Creating a simple front running bot
  • Adding complexity to it

Idea §

  • Look at the pending transactions pool of a chain (say Polygon)
  • Find a waiting trade that’s “market-moving”
  • Add in our buy and sell trades with respectively higher and lower gas
  • Wait for the orders to finish
