Frequently Asked Questions
Get clear answers on timelines, costs, security, and process for building your in-game marketplace.
A standard MVP deployment takes 4-6 weeks from kickoff to mainnet launch. This includes smart contract development, integration with your game engine, and frontend implementation. Complex features like cross-chain asset bridging or advanced governance can extend the timeline, which we scope and schedule transparently during discovery.
