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 that power your core business logic. Our process delivers secure, gas-optimized, and upgradeable code, ensuring your application is built on a robust foundation. Every contract undergoes rigorous internal review against common vulnerabilities before we recommend third-party audits.
We deliver a complete development lifecycle, not just code. From initial specification in
Solidity 0.8+orRustto final deployment scripts and verification, we own the technical risk.
- Custom Logic: Build unique
ERC-20,ERC-721, staking systems, DAO governance, or bespoke DeFi primitives. - Security-First: Development follows
OpenZeppelinstandards and includes threat modeling. We provide a detailed audit readiness package. - Full Ownership: You receive all source code, comprehensive documentation, and deployment guidance. We ensure you can operate and iterate independently.

Frequently Asked Questions
Get clear answers on our Zero-Knowledge Proof API integration process, security, and support.
Our standard Zero-Knowledge Proof API integration follows a structured 3-phase approach: Discovery & Scoping (1 week), Development & Integration (2-3 weeks), and Testing & Deployment (1 week). Most projects are fully deployed and live within 4-6 weeks from kickoff. Complex custom circuit development can extend this timeline, which we define and agree upon during the scoping phase.
