THE HERD

1. Keep your crossing off the public waterPoint your wallet at a private RPC instead of the default one. The transaction never enters the public mempool, so sandwich bots never see it. Flashbots Protect and MEV Blocker both work this way, and MEV Blocker returns a share of the backrun value to you.
2. Make the ordering stop matteringA batch-auction DEX like CoW Swap takes a signed intent instead of a raw transaction, then has competing solvers execute it at one clearing price for the whole batch. Being first in line stops paying, because arrival order is not what sets your price.
3. Narrow what can be taken from youA sandwich can only move the price as far as your slippage setting allows, so a tighter bound leaves less to extract. It cuts both ways: too tight and the swap fails during ordinary volatility, too loose and you hand the attacker room. There is no universally correct number.
4. Don’t move the whole herd at onceThe larger the swap, the further it moves the price, and the more there is to take — which is what makes it worth attacking. Splitting a large order, or spreading it over time, lowers what any single crossing is worth to a predator. It is not free either: more transactions mean more gas, and if the pieces are still large enough, each one can be sandwiched on its own.

No single measure removes the risk. Each of these shrinks a different part of the attack surface, and each has a cost. Not all MEV is malicious — the goal is to stop being an easy target, not to eliminate MEV.

The Sandwich Watch below is this site’s own record of the same pattern, read from blocks after they land.
