# Sandbox environment

> Sandbox merchant panel and API on testnets, with no mainnet funds.

The sandbox is available at:

Merchant panel: [https://sandbox-merchant.cryptonly.net](https://sandbox-merchant.cryptonly.net)\
Merchant api: [https://sandbox-api-merchant.cryptonly.net](https://sandbox-api-merchant.cryptonly.net/)

Use this environment to test invoices, hosted checkout pages, deposits, withdrawals, API integrations, and webhook handling without using real mainnet funds.

***

## Sandbox uses testnets only

The sandbox does **not** use mainnet networks. Do not send mainnet assets to sandbox addresses. Funds sent by mistake may not be recoverable.

Supported sandbox networks:

| Network         | Sandbox network |
| --------------- | --------------- |
| Ethereum        | ETH Sepolia     |
| BNB Smart Chain | BSC Testnet     |
| Base            | Base Sepolia    |
| TRON            | Tron Shasta     |
| Bitcoin         | BTC Testnet     |

## Sandbox vs production

| Environment | Purpose                 | Networks      | Funds         |
| ----------- | ----------------------- | ------------- | ------------- |
| Sandbox     | Testing and integration | Testnets only | Testnet funds |
| Production  | Real merchant payments  | Mainnets      | Real funds    |

4. Send testnet funds to the generated payment address.
5. Wait for the payment status to update.
6. Verify the payment in the dashboard.
