END-TO-END MIGRATION
Our Proof System Migration Capabilities
We architect and execute seamless, secure migrations from one proof system to another (e.g., SNARKs to STARKs, Plonk to Halo2) with zero downtime for your Layer 2 network.
01
Architecture & Feasibility Analysis
We conduct a deep technical assessment of your current zk-rollup architecture to design a migration path that minimizes risk and technical debt. Our analysis covers proof generation time, verification costs, and hardware requirements for the new system.

Circuit Porting & Optimization
Our team ports your existing business logic and state transitions into the new proof system's framework (Circom, Cairo, etc.). We focus on optimizing for prover efficiency, reducing verification gas costs on L1 by up to 40%.

Sequencer & Prover Integration
We rebuild and integrate the sequencer, prover, and verifier components to work with the new proof backend. This ensures transaction ordering, proof batching, and L1 settlement continue uninterrupted during and after the migration.

Technical & Commercial Questions
Proof System Migration FAQs
Answers to the most common questions from CTOs and engineering leads planning a Layer 2 proof system migration.
Our standard migration from audit to mainnet deployment takes 4-8 weeks. This includes a 2-week architecture review and planning phase, 2-4 weeks for core development and integration, and 1-2 weeks for final testing and deployment. For complex ecosystems with multiple custom circuits, timelines can extend to 12 weeks. We provide a detailed Gantt chart in the project proposal.
