Technical & Commercial FAQs
Common Questions on Event AppChain Development
Answers to the most frequent questions from CTOs and founders about building a custom Cosmos SDK chain for events, ticketing, or loyalty programs.
A standard Event AppChain with core features (token, NFT tickets, governance) deploys to testnet in 2-4 weeks. Full mainnet launch with audits, validator onboarding, and frontend integration typically takes 6-10 weeks. We provide a detailed sprint-by-sprint roadmap during discovery.
