overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications, from concept to mainnet deployment.

We architect and deploy production-grade smart contracts on EVM and Solana, ensuring gas efficiency, upgradeability, and robust security from day one. Our process delivers a fully audited MVP in 2-4 weeks.

We don't just write code; we engineer systems that protect your assets and scale with your business.

  • Custom Logic: ERC-20, ERC-721, DeFi protocols, DAOs, and bespoke business logic.
  • Security-First: Development with OpenZeppelin standards, followed by third-party audits from firms like CertiK or Quantstamp.
  • Full Lifecycle: From initial design and testing to deployment, verification, and ongoing maintenance.

ZK-ROLLUP PRIVACY ENGINEERING

Core Technical Capabilities We Deliver

We architect and deploy production-ready ZK-rollup privacy layers that enable compliant, user-centric data control without sacrificing performance or security.

DELIVERABLES

Business Outcomes for Your Platform

Our ZK-Rollup Privacy-Preserving Profiles deliver concrete, measurable results for your Web3 application. We focus on the technical outcomes that drive user adoption and platform security.

01

On-Chain Privacy with Zero-Knowledge Proofs

We implement zk-SNARKs or zk-STARKs to enable selective disclosure of user data. Users can prove attributes (e.g., KYC status, token holdings) without revealing the underlying data, ensuring compliance and user sovereignty.

02

Gas Cost Reduction & Scalability

By batching profile updates and verifications into a single ZK-Rollup proof, we reduce your users' transaction costs by up to 100x compared to direct L1 operations, enabling micro-transactions and mass adoption.

Regulatory-Compliant Identity Layer

Build a decentralized identity (DID) system that integrates with verifiable credentials. Our architecture supports GDPR/CCPA compliance by design, allowing data minimization and user-controlled revocation.

TRANSPARENT & PREDICTABLE

Our End-to-End Delivery Process

From initial design to mainnet deployment, our structured process ensures your ZK-powered privacy solution is delivered on time, within budget, and to the highest security standards.

01

Architecture & Design Review

We conduct a deep technical analysis of your use case to architect the optimal ZK-Rollup solution, selecting the right proving system (e.g., Plonk, Groth16) and data availability layer for your specific privacy and performance requirements.

Frequently Asked Questions

Get clear answers on development timelines, security, costs, and support for your custom privacy-preserving identity solution.

A production-ready MVP typically takes 6-10 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design and ZK-circuit specification, 3-4 weeks for core smart contract and circuit development, 1-2 weeks for integration and internal testing, and 1-2 weeks for a third-party security audit. Complex integrations (e.g., with existing KYC providers or multi-chain setups) can extend this timeline.
