Frequently Asked Questions
Common questions from CTOs and technical leads about hiring a dedicated ZK proof mobile contract developer.
We offer two primary models: Dedicated Developer (full-time integration with your team, ideal for long-term projects) and Fixed-Scope Project (for defined deliverables like a custom zk-SNARK circuit). All engagements start with a 1-2 week discovery phase to define scope, tech stack, and success metrics. We provide a single point of contact and integrate with your tools (Slack, Jira, GitHub).
