Frequently Asked Questions
Get clear answers on our development process, timelines, and technical approach for building your custom sovereign rollup.
A production-ready sovereign rollup with a custom ZK circuit and basic application logic typically takes 8-12 weeks from kickoff to mainnet deployment. This includes architecture design, circuit development, smart contract deployment, and rigorous security testing. For more complex ecosystems with multiple provers or custom data availability layers, timelines extend to 16-20 weeks.
