# Sandbox Environment ### Accessing the Sandbox Swapped.com's sandbox environment can be accessed via [**https://sandbox.swapped.com**](https://sandbox.swapped.com). Swapped.com's sandbox environment allows merchants to test their integration before going live. This ensures that all functionality is working as expected without real funds being charged. **The sandbox environment only offers BTC & ETH testnet cryptocurrencies, and supports only Visa/MasterCard** [**test card**](/swapped-ramp/readme/test-card.md) **payments. As a result of this, only those currencies and methods can be selected. Payments are limited to a 15 euro maximum.** ### Generating a Sandbox iFrame To generate a sandbox iframe, follow these steps: 1.
