CORE INFRASTRUCTURE
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
- Custom Logic: Tailored
ERC-20,ERC-721, and bespoke token standards. - Gas Optimization: Code reviewed for up to 40% lower transaction costs.
- Full Audit Support: Integrated testing with
Hardhat/Foundryand preparation for third-party audits.
From a 2-week MVP to a complex multi-chain protocol, we deliver contracts that are secure, efficient, and ready for mainnet.

PREDICTABLE DELIVERY
Our Development & Delivery Process
We deliver production-ready anonymous credential systems using a proven, security-first methodology. Our process ensures predictable timelines, zero-surprise deployments, and infrastructure you can trust from day one.
01
Architecture & Protocol Design
We design your credential system's core architecture, selecting the optimal zero-knowledge proof framework (Circom, Halo2) and on-chain/off-chain data flow. This phase defines security guarantees and scalability.

Frequently Asked Questions
Get clear answers on implementation timelines, security, and support for your privacy-first mobile application.
A standard deployment for a core credential issuance and verification flow takes 4-6 weeks from kickoff to production. This includes architecture design, smart contract development for the credential registry, mobile SDK integration, and security audits. Complex integrations with existing KYC providers or custom zero-knowproof circuits can extend this to 8-12 weeks. We provide a detailed project plan within the first week of engagement.
