PROVEN METHODOLOGY
Our Development Process
A structured, security-first approach to building production-ready private group chat applications with zero-knowledge proofs. We deliver auditable, scalable solutions from concept to mainnet.
01
Architecture & Protocol Design
We design the cryptographic architecture, selecting optimal ZK-SNARK/STARK frameworks (e.g., Circom, Halo2) and on/off-chain components. We define the privacy model, ensuring message confidentiality and group membership proofs are sound and efficient.

ZK Private Group Chats
Frequently Asked Questions
Get clear answers on development timelines, security, and support for your private messaging protocol.
From initial specification to mainnet deployment, a standard private group chat with core features (messaging, membership, basic admin) takes 4-6 weeks. Complex implementations with custom governance, multi-chain support, or advanced ZK circuits extend to 8-12 weeks. We provide a detailed project roadmap after the initial technical scoping session.
