ARCHITECTURE
Core Components of Our Custody Solution
Our institutional-grade custody is built on a modular, audited architecture designed for security, compliance, and seamless integration. Each component is engineered to meet the stringent requirements of financial institutions and high-volume Web3 applications.
01
ZK-Rollup Sequencer & Prover
Dedicated, high-availability sequencer for transaction ordering and zero-knowledge proof generation. Enables sub-second finality and reduces on-chain gas costs by over 90% compared to L1 execution.

Frequently Asked Questions
Get clear answers on how our secure, mobile-first custody solution integrates with your institutional workflow.
A standard deployment, including custom wallet UI/UX, MPC key management integration, and connection to your chosen rollup (e.g., Starknet, zkSync Era), takes 4-6 weeks. Complex integrations with existing back-office systems or custom smart contract modules may extend this to 8-10 weeks. We provide a detailed project plan within the first week of engagement.
