Core Concepts


Credentials represent user attributes like KYC/AML.

  • Credentials verify a user’s KYC/AML status
  • Credentials are checked during Safe Token transactions
  • Credentials are maintained by credential issuers
  • KYC, KYB, AML, Accredited Investor, and Jurisdiction credentials supported


Credentials are stored in a user’s wallet through BlueID and can verify user attributes like KYC, AML, or Jurisdiction. BlueID standardizes different types of Credentials across Credential Issuers to create one, uniform on-chain registry that Safe Tokens can query during transactions. As a result, BlueID can recognize Credentials from a variety of Credential Issuers, eliminating user frictions like repetitive KYC onboarding. Credentials can come in various forms (i.e., non-transferrable NFTs/SBTs, verifiable credentials) and are cryptographically tied to references stored on-chain. Credential Issuers mint credentials and are responsible for on-chain management, including minting, burning, expiration dates, and more.

Smart contract native checks

Credential checks occur at the smart contract level which improves the security, efficiency, and verifiability of Safe Token transactions. Importantly, no sensitive or personally identifiable information (PII) is stored on-chain.

Obtaining Credentials

Users can obtain credentials from Credential Issuers. Different credential Issuers may support different credential types, all of which recognizable during Safe Token transactions.

Credential Issuers

Credential issuers mint, maintain, and burn on-chain credentials. These can be thought of as service providers, providing the service of compliance for Safe Token transactions. If you are a Credential Issuer and are interested in securing the Blue Network, please contact


No personally identifiable information (PII) is stored on-chain for any Credentials on the Blue Network. In the event that a user wishes to file a case against a counterparty, the reference stored on-chain would point to the Credential Issuer responsible for the maintenance of that credential. In the near future, Blue Network will support zK-poof KYC.
