Connext Authentication

method: derived
source: openapi/connext-everclear-openapi.yml, https://docs.everclear.org/developers/api.md
summary: >-
  The Everclear ("Chimera") API declares no authentication at all. The merged OpenAPI carries
  no components.securitySchemes block and no security requirement on any of its 17
  operations, and the docs never mention an API key, token, or account. Authorization in
  Everclear is on-chain: the REST API only reads indexed protocol state and builds unsigned
  EVM/Solana/Tron TransactionRequest objects, which the caller then signs with their own
  wallet key and submits to the chain themselves. The signing key never touches Everclear.
model: none
schemes: []
security_requirements: []
findings:
  - id: no-security-schemes
    detail: components.securitySchemes is absent from every one of the 17 published OpenAPI documents.
  - id: no-operation-security
    detail: No operation declares a security[] requirement; all 17 are anonymous.
  - id: authorization-is-on-chain
    detail: >-
      POST /intents, POST /solana/intents and POST /tron/intents return a TransactionRequest
      (to/data/value/chainId or the chain equivalent) for the caller to sign locally. The
      caller's private key is the only credential in the flow and it is never sent to the API.
  - id: permit2-signature-in-body
    detail: >-
      IntentRequest accepts an optional permit2Params object (nonce, deadline, signature) —
      an EIP-2612/Permit2 signature produced client-side. This is a token-approval signature
      carried in the request body, not an API credential.
  - id: no-oauth-no-oidc
    detail: >-
      No /.well-known/openid-configuration or /.well-known/oauth-authorization-server on any
      host; scopes/ is therefore not applicable and is not emitted.

caveat: >-
  Unverifiable against a live host: https://api.everclear.org returned HTTP 530 on 2026-08-09,
  so this profile is derived from the published contract only. See lifecycle/connext-lifecycle.yml.
