notes: >-
  Violet has no traditional REST API with a securitySchemes block; its auth
  model is an OAuth 2.0-compliant authorization flow that mints Ethereum
  Access Tokens (EATs) plus on-chain verification against the VioletID
  Registry. This profile is captured from the developer documentation
  rather than derived from an OpenAPI spec.

  types: [oauth2, onchain-registry]

    description: >-
      An Ethereum Access Token is a signed compliance assertion issued by the
      Violet system (off-chain) and verified by the Violet Verifier smart
      contract (on-chain). It carries no direct PII; it only attests that a
      wallet address has enrolled and satisfies the compliance requirements of
      the integrating dApp. EATs are fully OAuth 2.0 compliant.

  - name: VioletIDRegistry
    type: onchain-registry
    description: >-
      An on-chain registry mapping a wallet address to compliance statuses.
      Any integrating dApp can query compliance status directly on-chain
      without a round-trip to Violet; only Violet can modify entries. Used as
      an alternative integration path to the EAT flow.
