PROVEN METHODOLOGY
Our Delivery Process: From Audit to Live System
A structured, four-phase approach to deliver a production-ready, secure, and scalable ZK-powered authenticity system. We provide clear deliverables and timelines at every stage.
01
Phase 1: Security & Architecture Audit
We conduct a comprehensive review of your existing product data and supply chain logic to design a secure, gas-efficient ZK circuit architecture. This includes threat modeling and selecting the optimal proving system (e.g., Circom, Halo2).
Deliverable: A detailed technical specification and security assessment report.

02
Phase 2: ZK Circuit & Smart Contract Development
Our engineers build the core zero-knowledge circuits that generate proofs of authenticity without revealing sensitive data. We simultaneously develop and test the on-chain verifier and management smart contracts using established libraries like SnarkJS and OpenZeppelin.
Deliverable: Fully auditable circuit code and deployed testnet contracts.

Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and rigorous internal audits before deployment.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with advanced features like vesting, minting controls, and tax mechanics. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, lending/borrowing modules, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, DAO governance frameworks, and cross-chain asset bridges.
We don't just write code; we deliver audit-ready contracts that reduce your time-to-audit by 50% and mitigate critical vulnerabilities before they become exploits.
Our engineers specialize in gas optimization, ensuring your contracts are cost-efficient for users. We provide comprehensive documentation and a 2-week MVP delivery for standard token implementations, getting you to market faster.
