Mainnet Sandwich Index · EIPsInsight

Because today's mempool is unencrypted, searchers can inspect pending swaps and sandwich victim trades (front-run + back-run). Lucid encrypts transactions until block execution to render sandwiching impossible. Figures below are a conservative on-chain floor across major DEXes, from Dencun onward.
