Our Delivery Methodology
We deliver StarkNet private payment solutions with a rigorous, phased approach designed for enterprise-grade security and rapid time-to-market.
01
Architecture & Design Sprint
We conduct a 2-week collaborative sprint to define your payment logic, privacy requirements (zk-proofs, account abstraction), and integration points. This phase establishes a clear technical blueprint and project timeline.

CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by senior blockchain engineers.
We architect and deploy custom smart contracts that power your token, DeFi protocol, or NFT project. Our senior engineers specialize in Solidity 0.8+, Rust (Solana/NEAR), and Move (Aptos/Sui).
Deliver a production-ready, gas-optimized contract suite in 2-4 weeks, backed by a 99.9% security-first development process.
- Security-First Development: Code follows OpenZeppelin patterns and undergoes internal review before formal audit.
- Full-Stack Integration: Contracts are delivered with deployment scripts, test suites, and frontend SDKs (
ethers.js/web3.js). - Post-Launch Support: We provide monitoring, upgradeability patterns, and emergency response planning.

Frequently Asked Questions
Get clear answers on how we build secure, scalable private payment systems on StarkNet.
A standard private payment system with core features (private transfers, shielded balances) takes 4-6 weeks from kickoff to mainnet deployment. Complex integrations (multi-asset support, custom compliance modules) can extend this to 8-10 weeks. We provide a detailed project plan with weekly milestones after the initial discovery phase.
