In this video, we:
– Cover the concept of front-running
– Write and deploy a smart contract that is vulnerable to front-running
– Put 0.035 ETH (~$8) in the contract
– Submit a transaction that is front-run by several parties, creating a gas-war to be the winner that claims this 0.035 ETH.
Even small, lesser-known projects are not immune to front-running due to this “generalized” front-running, which can abuse contracts without even understanding how these contracts operate.
