How it works

loss per swap = size × sandwich impact

monthly = per-swap × swap count

Worked example

Twenty $5,000 swaps a month leaking 0.6% each is $600 monthly, $7,200 a year quietly transferred to bots. A protected RPC endpoint costs nothing.

FAQ

How do I avoid sandwiches?

Use MEV-protected RPCs or private orderflow, set tight slippage, and split large swaps. Public mempool + loose slippage is the bot buffet.

How big is sandwich impact really?

Highly variable: near zero on deep pairs with tight slippage, several percent on thin meme pools with 10% tolerance. The impact field is yours to estimate per venue.
