Frequently Asked Questions
Get clear answers on our development process, timelines, and security for your custom zkRollup prediction market.
From initial spec to mainnet deployment, a standard prediction engine with core features (order book, liquidity pools, settlement) takes 6-10 weeks. Complex additions like cross-chain oracles or custom governance can extend this to 12-14 weeks. We provide a detailed sprint-by-sprint roadmap after the discovery phase.
