Cross-Chain ZK Voting Bridge
Frequently Asked Questions
Common questions from CTOs and technical leads evaluating secure, private voting infrastructure.
From kickoff to mainnet deployment, a standard implementation takes 4-6 weeks. This includes 2 weeks for smart contract development and audit, 1 week for ZK circuit design and proving, 1 week for frontend integration, and 2 weeks for testing and security review. Complex multi-chain integrations or custom governance logic can extend this timeline.
