StarkNet Cairo Verification
Frequently Asked Questions
Get clear answers about our specialized service for verifying Cairo smart contracts on StarkNet. We address common technical and process questions from CTOs and lead developers.
A standard verification for a single, well-documented Cairo 1.0 contract takes 5-7 business days. Complex protocols with multiple interdependent contracts or custom Cairo 0.x code typically require 2-3 weeks. We provide a detailed project plan with milestones after the initial code review.
