We architect and deploy production-ready smart contracts on EVM and Solana networks. Our development process is built for security and speed, delivering a custom MVP in 2-3 weeks.
ZK Identity Protocol Development
Smart Contract Development
Secure, audited smart contracts built to your exact specifications.
- Full Lifecycle Development: From ideation and
Solidity/Rustcoding to deployment and on-chain verification. - Security-First: Contracts are built with
OpenZeppelinstandards and undergo rigorous internal audits before external review. - Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption.
We don't just write code; we deliver secure, auditable, and maintainable blockchain logic that forms the foundation of your application.
What We Deliver
We architect and deploy production-ready ZK identity protocols that secure user data while enabling seamless Web3 interactions. Our focus is on delivering audited, scalable infrastructure that gets your product to market faster.
Custom ZK-Circuit Design
We design and implement zero-knowledge circuits tailored to your use case—from age verification to credit scoring—using Circom and Halo2. Our circuits are optimized for minimal proof generation time and on-chain verification cost.
On-Chain Verifier Contracts
Deployment of highly gas-optimized Solidity verifiers for your ZK circuits. We ensure compatibility with EVM chains (Ethereum, Polygon, Arbitrum) and L2s, with built-in upgradeability patterns for future-proofing.
Security & Audit Readiness
Comprehensive security review of your entire ZK stack, from circuit logic to verifier contracts. We prepare your protocol for formal audits with firms like Trail of Bits and provide remediation support.
Credential Issuance Gateway
A secure, scalable backend service for trusted entities to issue verifiable credentials (W3C VC standard). Supports selective disclosure and revocation, built with privacy-by-design principles.
Integration & Deployment
Full-stack integration of the ZK identity protocol into your existing application. We handle DevOps, monitoring, and provide documentation, enabling your team to own and scale the system.
Business Outcomes for Your Product
Our ZK Identity Protocol Development delivers tangible infrastructure and measurable results, not just theoretical concepts. We build production-ready systems that directly impact your product's security, compliance, and user experience.
Production-Ready ZK Circuits
We deliver custom-built, audited zero-knowledge circuits for identity verification, enabling privacy-preserving KYC/AML checks and credential issuance without exposing user data. Built with Circom and SnarkJS for optimal proving times.
Compliant Identity Wallets
Deploy secure, non-custodial wallets (ERC-4337 Account Abstraction) that manage verifiable credentials (W3C VC-DM). Integrates with existing KYC providers and supports selective disclosure for regulatory compliance.
Scalable Attestation Registry
A high-throughput on-chain registry (built on Ethereum L2s like zkSync or Polygon zkEVM) for issuing and revoking credentials. Features gas-optimized smart contracts with sub-cent transaction costs for mass adoption.
End-to-End Security Audit
Comprehensive security review covering ZK circuits, smart contracts, and frontend integration. Delivered with a final report from our in-house experts, following practices aligned with OpenZeppelin and Trail of Bits.
Developer SDK & API
A fully documented TypeScript/Go SDK and REST API for seamless integration into your existing application stack. Includes sample dApps, testing suites, and dedicated technical support.
Custom Integration & Migration
We handle the complete integration with your user database, legacy systems, or existing blockchain infrastructure. Specialized in migrating from centralized identity systems to decentralized, ZK-powered protocols.
ZK Identity Protocol Development Tiers
Transparent, outcome-focused packages for launching secure, compliant ZK identity solutions. Each tier includes full source code, documentation, and our standard security audit.

Our Development Methodology
We deliver production-ready ZK identity protocols through a structured, security-first approach that de-risks development and accelerates your time-to-market.
Architecture & Protocol Design
We design your ZK identity system's core architecture, selecting optimal proving systems (e.g., Circom, Halo2) and defining the trust model, credential schemas, and on/off-chain data flows.
Circuit Development & Optimization
Our engineers write and rigorously optimize zero-knowledge circuits for credential issuance, proof generation, and verification, focusing on proof size and verification gas costs.
Security Audits & Formal Verification
Every component undergoes internal review and external audit by firms like Spearbit or OtterSec. We employ formal verification tools for critical circuit logic.
Smart Contract Integration
We deploy and integrate verifier contracts (e.g., Solidity, Cairo) with your application, implementing gas-efficient proof verification and secure state management.
SDK & Developer Tooling
We provide client-side SDKs (TypeScript/JS) for seamless integration, handling proof generation, wallet interactions, and API communications.
Deployment & Ongoing Support
We manage mainnet deployment, establish monitoring for proof success rates, and provide ongoing support with defined SLAs for upgrades and maintenance.
Frequently Asked Questions
Get clear answers on our process, timelines, security, and support for building your private identity layer.
We deliver a production-ready ZK identity protocol in 6-10 weeks from kickoff to mainnet deployment. This includes a 2-week discovery and architecture phase, 3-5 weeks of core development and circuit design, and 1-2 weeks for security audits and deployment. Complex integrations (e.g., with existing KYC systems) may extend this by 1-2 weeks.
