Our Sequencer Protection & MEV Mitigation Capabilities
We architect and deploy custom, battle-tested sequencer protection systems for StarkNet applications, designed to secure your transaction flow and maximize user value.
01
Custom Sequencer Guard Implementation
We build and integrate dedicated sequencer guard contracts that act as a protective layer, validating and ordering transactions before they reach the StarkNet sequencer to prevent front-running and sandwich attacks.
