Frequently Asked Questions
Get clear answers on timelines, costs, and our development process for building secure, scalable smart accounts on StarkNet.
A standard smart wallet deployment takes 2-4 weeks from kickoff to mainnet. This includes architecture design, Cairo contract development, frontend integration, and security review. Complex multi-signature setups or advanced account abstraction features can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint breakdown during the discovery phase.
