zkMe Attestation Gateway is a decentralized identity verification solution leveraging zero-knowledge proofs (ZKPs) to enable privacy-preserving Know Your Customer (KYC) processes. It allows users to cryptographically prove credential validity without disclosing underlying personal data, supporting selective disclosure of information. The system facilitates cross-chain and cross-platform compatibility for digital attestations within Web3 ecosystems, while integrating compliance mechanisms aligned with regulatory frameworks like GDPR and MiCA. Its architecture emphasizes minimizing data exposure through cryptographic trust anchors rather than centralized storage of sensitive information.
