ZeroKYC is a Chrome extension designed to facilitate the transition of Web2 account ownership to Web3 KYC information while maintaining user privacy. By leveraging zero-knowledge proofs, this tool allows users to verify their identity without disclosing any personal data. The extension is specifically integrated with Polyflow, enabling a streamlined verification process that enhances user security and privacy.

The functionality of ZeroKYC involves several key steps: users must first log into Polyflow and connect their wallet, followed by selecting the Identity Verification option. The extension then opens the chosen KYC website in a new tab, where users can log in and complete their verification. Notable features include secure communication through public key encryption, retrieval of KYC status from trusted sources, and the generation of zero-knowledge proofs to ensure confidentiality throughout the verification process.
