Frequently Asked Questions
Common questions from CTOs and technical leaders evaluating our identity layer for their Web3 applications.
Our SDK integrates with your existing frontend to issue verifiable credentials (VCs) based on your chosen attestation logic (e.g., wallet age, transaction volume, KYC provider). Users maintain self-custody of their credentials via a non-custodial wallet. The layer acts as a universal verifier, allowing you to check attestations across any supported chain (Ethereum, Polygon, Arbitrum, etc.) without managing separate identity systems.
