Frequently Asked Questions
Get clear answers about our StarkNet and zkSync development process, security, and support for your fan engagement platform.
From kickoff to mainnet launch, a standard fan vault deployment takes 4-6 weeks. This includes 2 weeks for smart contract development and audit, 1 week for frontend integration, and 1-3 weeks for testing and security review. Complex features like multi-asset staking or cross-chain functionality can extend the timeline, which we scope and agree upon upfront.
