note: >-
  Cometh has no "sandbox mode" in the Stripe sense — there are no test-mode key prefixes, no magic test values and no
  simulator. The test surface is the public EVM TESTNETS: a project in the dashboard is created against one network, so
  a testnet project's apikey is by construction a test credential, and the getting-started tutorial is written against
  Polygon testnet / Arbitrum Sepolia. Everything recorded below is published verbatim in the docs; nothing is invented.
  Note that the testnet path is not fully self-serve: first-time users are told to "reach out so we can set you up with
  a Connect account and apiKey".
mode_separation:
  style: per-project-per-network
  key_prefixes: []
  test_key_prefix: null
  live_key_prefix: null
  note: >-
    One apikey per project, one project per chain. There is no documented prefix or flag distinguishing a testnet key
    from a mainnet key — the chain id in the endpoint path (bundler.cometh.io/{chainId}) is what selects test vs live.

  note: >-
    The counter smart contract the quick-start and SDK examples call (count() / counterList) to demonstrate a sponsored
    UserOperation end to end. Published verbatim throughout the docs.

- name: dashboard tutorial download
  note: >-
    The dashboard's "getting started" button downloads the tutorial repository pre-wired to the project's apiKey; the
    docs show the flow but the artefact is behind the dashboard login.
test_clocks:
  supported: false
  note: >-
    No time simulation. The one time-dependent flow — social recovery — has a real 24-hour challenge window that must
    elapse before /recovery/finalize succeeds, with no documented way to fast-forward it in testing.
console:
  url: https://app.cometh.io
  note: >-
    Project dashboard: create a project per network, read the project apiKey and apiSecret, register sponsored contract
    addresses for the paymaster, and download the tutorial. Login-gated; access to a first Connect account is
    human-gated via the contact link.
local_development:
  note: >-
    Passkeys require a secure context, so local development must run on https or localhost, and a passkey created on
    localhost is not usable from a deployed domain (passkeys are bound to origin). Documented in the FAQ as a testing
    constraint.
