COMPREHENSIVE SECURITY ASSESSMENT
What Our ZK-Rollup Recovery Audit Delivers
Our specialized audit goes beyond standard smart contract reviews to ensure your StarkNet application's recovery mechanisms are resilient, secure, and ready for mainnet. We deliver actionable insights, not just a report.
01
Recovery Logic & Escape Hatch Analysis
In-depth review of your application's emergency withdrawal mechanisms, pause functions, and upgrade paths. We verify that user funds can be safely recovered under all failure scenarios, including sequencer downtime and state corruption.

Frequently Asked Questions
Get clear answers about our specialized security audit process for StarkNet and ZK-Rollup recovery mechanisms.
A ZK-Rollup Recovery Audit is a specialized security review of the mechanisms that allow users to exit funds from a rollup to its parent chain (e.g., Ethereum L1) in case of a sequencer failure or network halt. It's critical because a flaw in the escape hatch or fraud proof system can lock millions in user funds. Our audit verifies the correctness, gas efficiency, and censorship-resistance of your recovery logic, ensuring your protocol's ultimate safety net is unbreakable.
