ZK-Proof Identity Verification Services

overview

SECURE FOUNDATION

Custom Smart Contract Development

Production-grade smart contracts built for security, scalability, and real-world utility.

We architect and deploy audit-ready smart contracts that form the core logic of your dApp. Our development follows OpenZeppelin standards and security best practices, ensuring your protocol is robust from day one.

Token Systems: Custom ERC-20, ERC-721, and ERC-1155 with advanced features like vesting, staking, and governance.
DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators, and derivative contracts.
Enterprise Logic: Multi-signature wallets, supply chain tracking, and custom business logic for real-world asset (RWA) tokenization.

We deliver a fully documented, tested, and deployable contract suite in 2-4 weeks, backed by a comprehensive security review.

Language Support

Private Identity Proof Aggregation

Aggregate multiple identity attributes (KYC, credit score, reputation) into a single, privacy-preserving proof. Users prove eligibility without revealing underlying sensitive data, enabling selective disclosure.

Selective Disclosure

Core Feature

Regulatory Compliance Integration

Build with compliance by design. Our systems integrate with regulated identity providers and generate audit trails for verifiers, helping applications meet AML/KYC requirements while preserving user privacy.

ENTERPRISE VALUE

Business Outcomes: Beyond Technical Implementation

Our ZK-Proof Identity Verification service delivers tangible business advantages, moving beyond the cryptographic layer to drive growth, compliance, and user adoption.

Regulatory Compliance & Audit Trail

Achieve GDPR, CCPA, and MiCA compliance by design. Our zero-knowledge proofs verify user credentials without exposing raw data, creating an immutable, privacy-preserving audit trail for regulators.

TRANSPARENT & PREDICTABLE

Our Delivery Process: From Design to Production

We deliver production-ready ZK-Proof identity systems on a fixed timeline. Our phased approach ensures security, compliance, and seamless integration with your existing infrastructure.

Architecture & Protocol Design

We design your custom ZK identity schema, selecting the optimal proving system (zk-SNARKs, zk-STARKs, or Plonk) and privacy model for your use case. This includes threat modeling and compliance mapping for GDPR, eIDAS, or AML regulations.

2-3 weeks

Frequently Asked Questions

Get clear, technical answers about our zero-knowledge proof identity service for Web3 applications.

A standard implementation takes 4-8 weeks from kickoff to production. This includes protocol design, circuit development, smart contract integration, and a full security audit. For proof-of-concepts or integrations with existing identity frameworks (like Polygon ID), timelines can be as short as 2-3 weeks.
