PROVEN PROCESS
Our Development Methodology
A systematic approach to building secure, scalable, and user-friendly mobile wallets on StarkNet. We deliver production-ready applications, not just prototypes.
01
Architecture & Strategy
We design a modular wallet architecture using Cairo 1.0, separating core logic from UI for security and future upgrades. This ensures your wallet can scale with user growth and integrate new StarkNet features seamlessly.

Frequently Asked Questions
Get clear answers on timelines, costs, security, and our development process for your StarkNet Cairo mobile wallet project.
A production-ready MVP with core features (account creation, asset transfer, dApp browser) typically deploys in 4-6 weeks. Complex integrations (multi-sig, advanced DeFi features, custom UI/UX) can extend this to 8-12 weeks. We provide a detailed sprint-by-sprint roadmap after the initial technical discovery.
