Frequently Asked Questions
Get clear answers about our ZK-Rollup voting client development process, timelines, and security.
A StarkNet ZK-Rollup voting client is a specialized application that enables secure, private, and scalable on-chain governance for DAOs and protocols. It leverages StarkNet's zero-knowledge proofs to bundle thousands of votes into a single, verifiable transaction on Ethereum, reducing gas costs by 90-99% and enabling complex voting logic (like quadratic voting) that would be prohibitively expensive on L1. You need one to scale your governance, reduce operational costs, and implement advanced, private voting mechanisms for your community.
