Frequently Asked Questions
Get clear answers on how we deliver verifiable, confidential data feeds for your Web3 applications.
A standard ZK Oracle integration for confidential data feeds takes 3-5 weeks from kickoff to mainnet deployment. This includes 1 week for requirements and architecture, 2-3 weeks for circuit development and smart contract integration, and 1 week for security review and deployment. Complex multi-source or custom attestation logic can extend this timeline, which we scope and quote upfront.
