EVM Game Client Development FAQs
Get clear answers to the most common questions from CTOs and product leads about building and deploying EVM-compatible game clients.
We follow a structured 4-phase process: Discovery & Design (1 week), Core Development (2-3 weeks), Integration & Testing (1-2 weeks), and Deployment & Support (1 week). For a standard Unity/Unreal client with wallet connectivity and basic NFT mechanics, total time-to-launch is typically 4-6 weeks. Complex projects with custom sidechains or advanced DeFi mechanics may extend to 8-12 weeks.
