model: testnet-networks
note: >-
  Sequence has no separate "test mode" key prefix; instead you point the same project
  access key at testnet chains. Each service exposes per-chain testnet hosts alongside
  mainnet. Only published values are recorded here; no test values are invented.

  note: >-
    This is the public example project access key embedded verbatim in the Sequence
    OpenAPI (ApiKeyAuth x-example); it is a documented sample, not a secret.
