Protect your data and empower your users to do the same

Self makes identity verification simple, seamless, and secure. Zero-knowledge (ZK) technology ensures that nobody, even the developers of the protocol, has access to users’ private information. Data is never stored by an external entity, and therefore, impossible to leak. No exposure, no guesswork.

What differentiates Self from KYC?

Self.xyz combines government-issued ID with zero-knowledge privacy to offer real identity without exposing personal data. Users scan their biometric passport and generate private proofs like age, names, nationality, sex, etc. - no data stored, no manual review, no risk.

Unlike other competitors we don’t require document uploads, we verify useful attributes, and covers a wide range of high-impact use cases, and not e.g. focused on elections. Self integrates easily via SDK compared to competitors and it does not rely on social reputation.

How is the data stored (external database)?

All data is stored locally on the user’s device — never on any servers. When a user verifies their identity, a verifiable credential is created and saved securely in the app. There’s no cloud storage, no centralized database, and no way for anyone - including Self - to access the data without the user's consent.

Who can access the information?

Only the user controls access to their information. With Self, all personal data and credentials are stored locally on the user’s device - not on a central server. No one (incl. Self) can access the information unless the user chooses to disclose it. When a user shares a proof (e.g., age or country), they share only that specific fact - not their full identity or any documents. ⇒ Privacy is built in. Disclosure consent is required.

Are there options for interoperability with other systems?

Yes, Self is built with interoperability in mind. Credentials are designed to follow emerging standards, enabling cross-platform verification and potential integration with other identity frameworks, as long as those systems support open, privacy-preserving standards.
