COMPLIANCE BY DESIGN
Architected for Regulatory Adherence
Our sovereign rollup infrastructure is engineered from the ground up to meet the stringent data privacy, jurisdictional control, and reporting requirements of regional financial authorities. We build compliance into the protocol layer, not as an afterthought.

REGULATORY BY DESIGN
Business Outcomes: Compliance as a Feature, Not a Burden
Our sovereign rollup architecture embeds regional compliance logic directly into the protocol layer, turning regulatory adherence from a cost center into a competitive advantage.
01
Jurisdiction-Specific Rule Engine
We deploy a custom rule engine that enforces regional KYC/AML, transaction limits, and data residency requirements at the sequencer level, ensuring compliance is automated and immutable.

Technical and Compliance FAQs for Sovereign Rollups
Answers to the most common technical and regulatory questions from FinTechs and enterprises deploying compliant sovereign rollups.
A standard sovereign rollup deployment takes 4-8 weeks, depending on the complexity of your consensus rules and data availability requirements. The timeline includes: 1) Week 1-2: Architecture & compliance mapping. 2) Week 3-5: Core development, sequencer setup, and bridge implementation. 3) Week 6-7: Internal testing and security audit integration. 4) Week 8: Staged deployment and final compliance verification. We provide a fixed-scope project plan at kickoff.
