Technical & Commercial Considerations
Sequencer Development FAQs
Answers to the most common questions CTOs and technical founders ask when evaluating a sovereign rollup sequencer development partner.
For a standard sovereign rollup sequencer with a custom state transition function, we deliver a production-ready MVP in 4-6 weeks. This includes core sequencing logic, data availability integration, and a basic prover setup. Complex systems with advanced MEV resistance or multi-chain interoperability can extend to 8-12 weeks. We follow a phased delivery model with weekly demos.
