Hybrid Vault Architecture: Key Questions
Get clear, technical answers to the most common questions our enterprise and startup clients ask before committing to a hybrid vault solution.
We follow a structured 4-phase delivery model. Discovery & Design (1 week) finalizes architecture and SLAs. Core Development (2-3 weeks) builds and unit-tests the on-chain smart contracts and off-chain service layer. Integration & Testing (1 week) connects to your existing systems and conducts security reviews. Deployment & Handoff (1 week). Most projects deploy a production-ready hybrid vault in 4-6 weeks from kickoff. We provide a detailed Gantt chart after the discovery phase.
