ZK Vault is a privacy-focused browser extension designed for Chrome users, enabling them to verify personal attributes without disclosing sensitive information. This tool employs zero-knowledge proofs to allow users to prove claims, such as their country or email domain, while ensuring their data remains secure and private. With features like local proof generation and selective sharing, ZK Vault prioritizes user confidentiality and control.

The extension generates cryptographic proofs that are stored locally in the browser, eliminating the need for server storage or tracking. Users can share proofs with trusted websites while maintaining anonymity, as the system requires explicit permission for data access. Additionally, ZK Vault supports seamless integration for developers, making it an ideal solution for applications that require privacy-preserving verification. This innovative approach to identity management aligns with modern privacy standards, catering to both individual users and developers.
