PROVEN FRAMEWORK
Our Methodology for EVM Protocol Transformation
A systematic, security-first approach to migrate and optimize your existing EVM protocol for zero-knowledge proof environments, minimizing risk and maximizing performance.
01
Architecture & Feasibility Audit
We conduct a deep technical analysis of your current Solidity contracts and protocol logic to identify ZK compatibility, gas inefficiencies, and architectural constraints. This initial blueprint defines the optimal migration path and scope.

EVM ZK Transformation FAQs
Get clear answers to the most common questions CTOs and founders ask when evaluating a ZK protocol transformation.
A standard EVM-to-ZK transformation project takes 4-8 weeks from kickoff to mainnet deployment. This includes 1-2 weeks for architecture and circuit design, 2-4 weeks for development and rigorous internal testing, and 1-2 weeks for final audits and deployment. Complex protocols with custom state transitions or novel cryptographic primitives may extend this timeline, which we scope and quote for upfront.
