Frequently Asked Questions
Get clear, technical answers about our specialized compliance engine development service for Optimistic Rollups.
A standard deployment for a custom compliance engine, including fraud proof verification, data availability integration, and challenge period logic, takes 4-8 weeks. This timeline covers design, development, security audit integration, and deployment to a testnet. Complex requirements like multi-chain support or novel dispute resolution mechanisms can extend this to 12 weeks. We provide a detailed project plan within the first week of engagement.
