  Cross-cutting technical standards Violet Protocol's compliance/identity
  rails conform to, per the developer documentation. Violet issues Ethereum
  Access Tokens (EATs) as OAuth 2.0-compliant access tokens and anchors
  identity via W3C DID/Verifiable Credentials and Ethereum token standards.
  This asserts technical-standard conformance only; it is not a published
  audit certification (no SOC 2 / ISO 27001 program was found), so no
  Compliance pointer is emitted.
standards:
  - id: oauth2
    conforms: true
    evidence: >-
      Docs state Ethereum Access Tokens are "fully OAuth 2.0 compliant" access
      tokens; the specification does not mandate a JWT token format.

  - id: oidc
    conforms: true
    evidence: >-
      The ethereum-access-token project is described as "Solidity-based OIDC
      for generating, issuing and verifying access tokens for smart contracts".
    source: https://github.com/violetprotocol/ethereum-access-token
  - id: eip-712
    conforms: true
    evidence: >-
      EATs are signed messages that comply with EIP-712 (typed structured data
      hashing and signing).

  - id: w3c-did
    conforms: true
    evidence: >-
      Identities are modeled with W3C Decentralized Identifiers (DID-core) as a
      core concept.

  - id: w3c-verifiable-credentials
    conforms: true
    evidence: >-
      "Violet stores all information about users in the form of Verifiable
      Credentials" per the W3C VC data model.

  - id: eip-721
    conforms: true
    evidence: >-
      HumanboundToken is an ERC-721 representation of off-chain unique
      humanhood used within the identity system.

  - id: eip-1238
    conforms: true
    evidence: >-
      Violet publishes an EIP-1238 implementation for non-transferable
      (soulbound) tokens used in on-chain identity/credential representation.
