ZERO-DOWNTIME TRANSITION
Our Migration & Upgrade Capabilities
Migrate your existing privacy infrastructure to advanced protocols like Aztec, Penumbra, or FHE frameworks with guaranteed security and no disruption to your users.
01
State-Preserving Protocol Migration
We architect and execute migrations from legacy privacy systems (e.g., Tornado Cash, zk-SNARKs v1) to modern ZK-rollups or FHE protocols. Our process ensures all user balances, transaction history, and protocol state are verifiably transferred.

Technical & Commercial Considerations
Privacy Protocol Migration FAQs
Answers to the most common questions from CTOs and technical leads evaluating a privacy protocol upgrade. Based on our experience migrating 30+ projects to protocols like Aztec, ZKsync, and Polygon Miden.
A standard migration from a transparent EVM chain to a privacy-enabled L2 (e.g., Aztec) takes 4-8 weeks. This includes: 1-week architecture review, 2-4 weeks for core logic porting and ZK-circuit integration, 1 week for internal testing, and 1-2 weeks for audit preparation. Complex DeFi protocols with custom circuits can extend to 12 weeks. We provide a detailed week-by-week project plan during discovery.
