Technical & Commercial FAQs
Answers to the most common technical and commercial questions about implementing a decentralized, pay-as-you-go VPN service.
A standard implementation takes 2-4 weeks from kickoff to mainnet deployment. This includes smart contract development, frontend integration, and security review. Complex features like multi-chain support or custom tokenomics can extend this to 6-8 weeks. We provide a detailed project plan within the first 48 hours of engagement.
