  Figment's test surface is environment-scoped API keys plus real public testnets, not synthetic
  fixtures. There are no magic test card numbers or hosted mock tokens — a test-environment key
  transacts against the real testnet/devnet of each supported protocol, so testing requires testnet
  funds obtained from each protocol's own faucet. Values below are published by Figment; nothing here
  is invented.

test_networks:
  note: >-
    Values taken verbatim from the `network` enums published in the OpenAPI 3.1.0 and from the
    Elements documentation. Each is a public protocol testnet, not a Figment simulator.
  networks:
  - protocol: Ethereum

  - protocol: Solana

  - protocol: Babylon (BTC staking)

  component_library: "@figmentio/elements"
  requirement: >-
    Figment issues an appId and allowlists the domain the widget renders on — the docs direct
    integrators to contact Figment rather than self-serve. Testnet is supported (Hoodi for ETH,
    Devnet for Solana, Signet for Babylon).

x402_test_surface:
  present: true
  recipe: https://docs.figment.io/recipes/test-x402-api-on-solana-devnet.md
  description: >-
    Figment publishes a recipe for exercising the x402 payment facilitator against Solana devnet.
test_clocks: false
fixture_tooling: false
simulation_values:
  published: false
  note: >-
    No decline/failure simulation identifiers, magic addresses, or forced-error triggers are
    documented. Failure paths must be exercised against live testnet conditions.
recipes:
  url: https://docs.figment.io/recipes
  note: >-
    Eighteen runnable end-to-end recipes (hot-wallet and Fireblocks custody variants for ETH, SOL,
    ADA, AVAX, NEAR, plus x402) are the closest thing Figment ships to a guided sandbox.
