What is Salmonella?
Salmonella intentionally exploits 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. It’s a regular ERC20 token, which behaves exactly like any other ERC20 token in normal use-cases. However, it has some special logic to detect when anyone other than the specified owner is transacting it, and in these situations it only returns 10% of the specified amount - despite emitting event logs which match a trade of the full amount.
