Privacy Solutions

Zero-Knowledge (ZK) Solutions

Prove what matters. Hide what doesn't. Build privacy-preserving apps with zk-SNARK integrations for private chat & transactions, plus secure ZK circuits, verifiers, and audits.

Talk to a ZK Engineer

At InnovariaTech, we design and integrate zero-knowledge proof systems so your users can verify claims without exposing sensitive data. If you're building products where privacy and trust are non-negotiable—private chat, confidential transactions, identity checks, or compliance proofs—our team helps you ship ZK solutions that work in production.

Whether you need zk-SNARK integrations for chat & transactions, a custom proving circuit, or end-to-end on-chain/off-chain verification, we'll help you pick the right approach, implement it safely, and make it usable for real people.

Build trust, not exposure: verify without revealing

A zero-knowledge proof lets one party prove a statement is true without revealing the underlying information. In practice, that means you can confirm things like "this transaction is valid" or "this user is allowed" while keeping the private details hidden. This is a powerful layer for data privacy, especially when combined with encryption, secure key management, and strong application security.

What we deliver

Comprehensive ZK solutions designed to protect privacy while enabling verification.

🏗️

1) ZK architecture & product design

We map your product goals to a ZK-friendly architecture—what should be proven, what must remain private, and what must be public for verifiability. You'll get a clear plan for proof generation, verification, UX, and performance constraints.

2) zk-SNARK circuit development & verification

We implement circuits that prove the right thing—no more, no less. That includes constraint design, witness generation, test vectors, and verifier integration (on-chain smart contracts and/or server-side verification APIs).

3) Private chat & messaging proofs (ZK-assisted)

For chat systems, ZK can be used to prove membership, authorization, rate limits, or "policy-compliant" messages without exposing identities or content. Paired with modern encryption, this helps reduce metadata leakage while keeping moderation and abuse prevention possible.

4) Private and confidential transactions

We implement confidential transactions where amounts, participants, or conditions are hidden, but validity is publicly verifiable. This can be used for payments, payroll, B2B settlement, asset transfers, and privacy-preserving DeFi flows—without turning your system into a black box.

5) Identity and access proofs

Build privacy-preserving identity management: prove age, region, accreditation, or KYC/KYB status without disclosing full personal data. This is especially useful for regulated products that need compliance while respecting user privacy.

6) Integration & infrastructure

ZK projects are not just math—proofs need reliable systems. We build proving services, queues, caching, monitoring, and API integration with your existing apps and wallets. You get deployment-ready components, not a research demo.

ZK use cases we implement

Real-world applications where zero-knowledge proofs deliver privacy and trust.

Compliance-ready proofs

Prove "this wallet passed checks" or "this transaction meets limits" without revealing the full dataset. Useful for fintech, exchanges, marketplaces, and enterprise blockchain workflows.

Privacy-preserving payments and transfers

Enable private transactions and confidential transactions while still supporting audits, controls, and verifiable rules.

Private dApps and smart contracts

Add privacy guarantees to decentralized applications by proving sensitive logic off-chain and verifying results on-chain with smart contracts.

Secure authentication

Support privacy-friendly login and access control patterns (including optional biometric authentication flows) without exposing raw identifiers.

Our ZK integration process

A guided, transparent journey—from defining privacy requirements to shipping secure ZK solutions.

01
🔍

Discovery workshop

We define your threat model, your privacy requirements, and your performance targets. We also decide what level of privacy is needed (content, metadata, transaction amounts, identity attributes, etc.).

02

Proof system selection

We select the proving approach that fits your use case (for example, zk-SNARK vs alternatives) based on constraints, performance, setup requirements, and verifier costs.

03
⚙️

Circuit & verifier implementation

We build the circuit, test it heavily, and integrate verification in the right place: on-chain smart contracts, backend APIs, or both. We also document the proving flow for your engineering team.

04
🎨

UX & product hardening

We turn "cryptography" into a product feature: sensible error handling, clear user flows, and safe defaults. This is where many ZK projects fail—so we obsess over usability.

05
🔒

Security review & launch support

We add circuit-level tests, integration tests, and reviews focused on application security. For high-stakes products, we'll help you prepare for third-party auditing and a staged rollout.

Security-first development

ZK systems can fail in subtle ways—often not in the math, but at the edges: bad assumptions, missing checks, unsafe key handling, or leaky APIs. Our approach includes:

  • Secure design reviews and threat modeling
  • Test vectors and negative-case testing (prove what should fail)
  • Strong encryption and key management patterns
  • Verification logic hardening for smart contracts and backend services
  • Performance profiling and safe rate limiting

Tech stack

We're tool-agnostic and choose what fits your product, but our teams commonly work with:

ZK tooling

Circom, SnarkJS, Halo2, Noir, Cairo/STARK tooling

Backend

Node.js, Rust, Python

On-chain

Solidity smart contracts, EVM-compatible chains and Layer 2s

Infrastructure

Containerized proving services, observability, secure secret storage
