Optimistic Rollup Data Availability FAQs
Get clear, expert answers to the most common questions about implementing and managing data availability for your Optimistic Rollup.
Our standard deployment for a custom Optimistic Rollup with a robust data availability layer takes 4-6 weeks from kickoff to mainnet launch. This includes architecture design, smart contract development, integration with a chosen DA solution (e.g., Celestia, EigenDA, Avail), and comprehensive testing. We follow a phased delivery model with weekly demos to ensure alignment and rapid iteration.
