Frequently Asked Questions
Get clear, technical answers about our development process, timelines, and security standards for building your custom settlement layer.
A standard, production-ready Optimistic Rollup settlement layer with core sequencer, bridge, and fraud proof system takes 6-10 weeks from kickoff to mainnet deployment. This includes architecture, smart contract development, integration testing, and a formal security audit. Custom features like advanced data availability solutions or multi-chain support can extend this timeline.
