Anonymity-Preserving Attestation Gateway
A gateway service enabling issuers to provide verifiable attestations to user-held Decentralized Identifiers (DIDs) without learning the user's broader identity or transaction history. We build the privacy layer that separates credential issuance from identity exposure.

Frequently Asked Questions
Get clear answers on how our gateway secures your on-chain identity while preserving user privacy.
Our gateway uses zero-knowledge proofs (ZKPs) and selective disclosure protocols. Users generate verifiable credentials off-chain and can prove specific claims (e.g., "I am over 18") without revealing the underlying data (their birthdate). The gateway acts as a trustless verifier, ensuring no personally identifiable information (PII) is ever stored on-chain or in our systems.
