Sandwich lab
The same attack on two venues. A bot buys just before the victim and sells just after. On an AMM the victim pays the price the bot pushed up. On Metronome all three orders land in the same batch and clear at one price, so there is nothing to push.

Recorded on Monad testnet on Oct 4 (looking for a newer run…): 100k MON victim, 100k MON attacker. The attacker's loss on Metronome is the taker fee.attack txsettle tx
Run it yourself
One transaction attacks both venues; a second one settles the Metronome batch and reports. You play every role (maker, attacker, victim) with about 200k WMON and 6k AUSD. On testnet the lab runs on its own Metronome market with test tokens (tWMON/tAUSD) that the app mints for you, so you only need a little MON for gas.
