ZK-Rollup Privacy for Shareholder Registry
We implement zero-knowledge rollups (StarkNet, zkSync) to manage cap tables with transaction privacy. Individual balances are hidden, while the public state root ensures auditability and compliance.

ZK-Rollup Privacy for Shareholder Registry
Frequently Asked Questions
Common questions from CTOs and technical founders about implementing private, on-chain shareholder registries with ZK-Rollups.
A standard deployment for a ZK-Rollup-based shareholder registry takes 4-6 weeks from kickoff to mainnet launch. This includes smart contract development, zero-knowledge circuit design, frontend integration, and a full security audit. Complex requirements like multi-asset support or custom governance can extend the timeline.
