TrustLayer is the universal verification network on top of NotaryChain. Any third-party verifier, from KYC providers and employers to license boards and banks, can issue cryptographic attestations about a user. Anyone can query the federated trust graph in real-time.

API calls
Three roles, one federated graph.
KYC providers, license boards, employers, banks. Register with NotaryChain, get a TrustLayer API key, issue cryptographic attestations about a user_id.
Every NotaryChain user automatically has a federated trust graph. Living Identity scores, partner attestations, and notarization history all roll up into one verifiable score.
Drop our SDK snippet on any signup, login, or checkout flow. One API call returns a 0-100 trust score plus the full evidence chain. Auditable forever.
Two lines of code. No SDK install. Works on any platform.
