PROACTIVE DEFENSE
Our Cross-Rollup MEV Security Analysis
We don't just monitor for MEV; we analyze your entire cross-rollup architecture to identify and quantify leakage risks before they impact your users or protocol revenue.
01
Cross-Chain Transaction Flow Analysis
We map and simulate the complete lifecycle of user transactions across your supported rollups (Arbitrum, Optimism, zkSync, etc.) to pinpoint where value is most vulnerable to extraction by searchers and validators.

Cross-Rollup MEV Protection
Frequently Asked Questions
Get clear answers on how we secure your rollup's value from sophisticated MEV attacks.
Our solution deploys a multi-layered defense. We implement custom sequencer logic to detect and reorder malicious transactions, integrate real-time mempool monitoring across L1 and L2s to identify predatory arbitrage, and apply privacy-preserving encryption techniques for sensitive transactions. This prevents front-running, sandwich attacks, and arbitrage leakage specific to cross-rollup environments.
