Cairo SDK Development FAQ
Get clear answers on timelines, costs, and our proven process for building robust StarkNet SDKs with Cairo.
A standard Cairo SDK for a specific protocol (e.g., a custom DEX or lending pool) typically takes 2-4 weeks from kickoff to production-ready delivery. Complex, multi-protocol SDKs with advanced features like account abstraction integration can extend to 6-8 weeks. We provide a detailed sprint-by-sprint timeline after the initial technical scoping session.
