DELIVERABLES
Business Outcomes for Your Protocol
Our Sovereign Data Vault for DeFi delivers concrete, measurable results that directly impact your protocol's security, performance, and market position.
01
Enhanced Security & Compliance Posture
We deploy a dedicated, air-gapped data vault with zero external dependencies, eliminating single points of failure. All data is encrypted at rest and in transit, with access governed by your protocol's own multi-sig governance. This architecture is designed to meet the security standards expected by institutional partners.

Frequently Asked Questions
Get clear answers on how our enterprise-grade data vault secures and operationalizes your DeFi protocol's critical information.
A Sovereign Data Vault is a dedicated, secure infrastructure layer for managing your protocol's most sensitive data—like user positions, risk parameters, and oracle inputs—separate from the public blockchain. It's essential for protocols handling high-value assets or complex logic, as it prevents front-running, reduces gas costs for data-heavy operations, and provides a single source of truth for off-chain services like dashboards and risk engines. Without it, you risk data fragmentation, security vulnerabilities, and a poor user experience.
