PROVEN METHODOLOGY
Our Development & Verification Process
A rigorous, multi-stage framework designed to deliver secure, auditable, and production-ready Cairo contracts on StarkNet. We combine deep protocol expertise with formal verification to ensure your smart contracts are a business asset, not a liability.
01
Architecture & Specification
We begin with a formal requirements analysis, defining invariants, state transitions, and integration points. This creates a verifiable blueprint for your Cairo system, preventing costly logic errors before a single line of code is written.

Technical & Commercial Questions
StarkNet Cairo Development FAQ
Answers to common questions from CTOs and technical founders about our StarkNet Cairo smart contract development process, timelines, and guarantees.
Our standard development sprints are 2-3 weeks. A typical project, such as a custom AMM or NFT marketplace, takes 4-8 weeks from kickoff to mainnet deployment. This includes architecture, Cairo 1.0 development, comprehensive testing, and security review. Complex protocols like cross-chain bridges or zk-rollup applications may take 10-12 weeks. We provide a detailed project plan with milestones during the initial scoping call.
