ZK-POWERED MESSAGING INFRASTRUCTURE
Core Technical Capabilities We Deliver
We build and deploy production-ready, anonymous group messaging systems using zero-knowledge proofs. Our solutions are designed for CTOs who need to integrate privacy-first communication into their FinTech or Web3 applications.
03
On-Chain & Off-Chain Architecture
We architect hybrid systems where proof verification is on-chain (EVM/L2) for trust, while proof generation and message relaying are off-chain for scalability and user experience.
04
End-to-End Encryption Layer
Beyond anonymity, we integrate robust E2E encryption (e.g., Signal Protocol) for message content, ensuring confidentiality is maintained from sender to recipient.
05
Gas-Optimized Smart Contracts
Our verification contracts are written in Solidity 0.8+ with OpenZeppelin libraries, rigorously audited and optimized to minimize transaction costs for your users.
06
Production Deployment & Monitoring
We handle full-stack deployment, including prover servers, relayers, and indexers, with 24/7 monitoring, alerting, and 99.9% uptime SLAs for critical infrastructure components.

DELIVERABLES
Business Outcomes for Your Project
Our Zero-Knowledge Proof Anonymous Group Messaging service delivers tangible results for your product's security, compliance, and user trust. We focus on measurable outcomes, not just features.
01
Provable Privacy & Compliance
Deploy messaging with mathematically verifiable anonymity, enabling you to meet stringent data privacy regulations (GDPR, CCPA) without sacrificing functionality. We deliver ZK circuits that prove message integrity without revealing sender identity.

Frequently Asked Questions
Common questions from CTOs and technical founders evaluating private group messaging infrastructure.
A standard ZK anonymous group messaging MVP with core features (on-chain group management, off-chain messaging, basic anonymity set) deploys in 4-6 weeks. Complex implementations with custom circuits, multi-chain support, or advanced moderation tools typically take 8-12 weeks. We provide a detailed sprint-by-sprint roadmap after the initial architecture review.
