PROVEN METHODOLOGY
Our Development & Delivery Process
We deliver production-ready, privacy-enhanced ZK smart wallets through a structured, security-first process. This ensures predictable timelines, zero audit findings, and seamless integration.
01
Architecture & Specification
We define your wallet's privacy model (ZK-SNARKs vs. ZK-STARKs), user flow, and smart contract architecture. Deliverables include technical specs and a detailed project roadmap.

Expert Insights
Frequently Asked Questions on ZK Wallet Development
Get clear answers on development timelines, costs, security, and technical implementation for your privacy-enhanced smart wallet project.
A standard privacy-enhanced smart wallet with core features (account abstraction, ZK proofs for selective disclosure, multi-chain support) takes 4-6 weeks from kickoff to mainnet deployment. Complex integrations (custom ZK circuits, novel recovery mechanisms) can extend this to 8-12 weeks. We provide a detailed sprint-by-sprint roadmap during discovery.
