PROVEN METHODOLOGY
Our ZK Circuit Development Process
We deliver production-ready confidential transaction circuits through a rigorous, four-phase process designed for security, auditability, and seamless integration into your CosmWasm application.
01
1. Architecture & Specification
We begin by defining the precise privacy requirements and data flow for your CosmWasm contract. This includes selecting the optimal proving system (e.g., Groth16, PLONK) and designing the circuit logic to minimize constraints and gas costs.

2. Circuit Implementation
Our engineers write the ZK circuit in Circom or Halo2, implementing the specified logic with a focus on security and performance. We build comprehensive test suites using frameworks like SnarkJS to verify correctness against edge cases.

Frequently Asked Questions
Get clear answers on our development process, security, and timelines for implementing private transactions on Cosmos.
A standard deployment of a CosmWasm confidential circuit with basic private transfer logic takes 2-3 weeks from kickoff to mainnet. Complex protocols with custom zero-knowledge proof logic or multi-party computation can take 4-8 weeks. We provide a detailed project plan with weekly milestones after the initial technical scoping session.
