# Sandbox

> Run test deposits before going to production.

<Note>
  **In progress.** A sandbox will let you run the full deposit flow with no real funds -
  success, failure, and pending paths. Test keys, the sandbox URL, and test values will be
  documented here once the environment is built.
</Note>

A proposed design - test credentials, simulating outcomes, and simulating time (for the
escrow expiry path) - is in [Proposals → Sandbox](/proposals/sandbox) for team review.
