However, nothing is risk-free on the blockchain, and exploitative trading strategies such as sandwich trading and front-running actually increase in risk the more the engineer attempts to generalise their ability to capture opportunities.

To illustrate to novice traders the risks of playing in the mempool, I have conducted a demonstration of a new trading alpha I call “Salmonella”, which involves intentionally exploiting the generalised nature of front-running setups. The goal of sandwich trading is to exploit the slippage of unintended victims, so this strategy turns the tables on the exploiters.
