<Update label="July 2026">
  ## Card issuance in sandbox

  You can now issue cards directly in the sandbox environment. Test the full card
  lifecycle—[cardholder setup](/cards/onboarding/cardholder-setup),
  [issuing cards](/cards/card-management/issuing-cards),
  [funding sources](/cards/card-management/funding-sources), and
  [freezing and closing](/cards/card-management/freezing-and-closing)—end to end
  before going live, without touching production.

  See [Cards sandbox testing](/cards/platform-tools/sandbox-testing) to get started.

  ## Expanded country coverage

  Grid now supports additional countries, including **China**, broadening the corridors
  available for global payments. Review the currencies and rails available in each region
  in [Currencies and rails](/platform-overview/core-concepts/currencies-and-rails).
