Technical & Commercial Details
StarkNet Testnet Development Suite FAQs
Get clear, specific answers to the most common questions from CTOs and technical founders evaluating our Cairo & StarkNet testnet development services.
Our standard StarkNet testnet deployment takes 2-4 weeks from kickoff to mainnet-ready code. This includes smart contract development in Cairo, integration with your front-end, comprehensive testing, and deployment to the StarkNet testnet. Complex protocols with custom logic or novel cryptographic proofs may extend to 6-8 weeks. We provide a detailed sprint-by-sprint timeline during the initial scoping call.
