Frequently Asked Questions
Get clear answers on our process, timeline, and technical approach for building your custom ZK-Rollup settlement layer.
A standard ZK-Rollup settlement layer deployment takes 4-8 weeks from kickoff to mainnet launch. This includes 1-2 weeks for architecture design, 2-4 weeks for core development and circuit implementation, and 1-2 weeks for testing and audit preparation. Complex integrations with existing DeFi protocols or custom fraud proofs can extend this timeline, which we scope and quote for upfront.
