On-Chain KYC^® 2.0

The Standard for Granular, Secure, Decentralized Attestations

A flexible, powerful solution for blockchain identity verification and attestation. Using open standards, we seamlessly verify users without compromising their privacy or your own security.

Build Trust with Verifiable, On-Chain Credentials

On-Chain KYC^® 2.0 empowers you to issue on-chain attestations for your users, creating a verifiable and reusable digital identity on or off the blockchain. Instead of building and maintaining your own smart contracts, we utilize existing attestation services on Ethereum, Solana, and other compatible chains. This allows for greater interoperability and simplifies the integration process for your dApp or platform.

Your systems never need to touch or store end-user PII

You receive only the verification result (the attestation)

Attestations are issued by you and are powered by Blockpass

Choose your attestation model

On-Chain Attestations

Write attestations directly to the blockchain for easy composability and verification.

Off-Chain (Zero-Knowledge)

Store in hash-chain while the attestation lives off-chain — delivering a compatible, privacy-preserving solution.
