# Getting Started

To get started, please ensure you have compatible digital asset wallet that is funded with Sepolia ETH or Fuji AVAX to pay for gas.  

{% hint style="info" %}
**IMPORTANT:** If you are using a wallet that requires you to whitelist addresses you interact with (like Fireblocks), you will need to whitelist the [Sandbox contract addresses](/opentrade-sandbox/contract-addresses.md) before you begin testing. Fireblocks users must also configure their TAP to allow contract calls to OpenTrade smart-contracts. User guides for doing these actions can be found [here](broken://spaces/vTyVj8bFfTwNzXbKANlO/pages/H3vuoj8z92pNuPBGqq2m#user-guides). 
{% endhint %}

1. Let your OpenTrade account manager know your wallet address and which network(s) you'd like to test on and we will (i) whitelist your wallet so you can invest in the sandbox vaults (ii) send you Mock USDC to test with.
2. Visit the [Sandbox URL](/opentrade-sandbox/sandbox-api-and-web-app.md) and connect a [supported](broken://spaces/vTyVj8bFfTwNzXbKANlO/pages/oJyj5q4GQuE5tahKYx9L) digital asset wallet - you can make test deposits and withdrawals from the sandbox vaults you've been whitelisted on. 
3. If you are planning on using the Sandbox API, let us know and we will also provide you a Sandbox API Key. The API documentation can be found [here](/opentrade-sandbox/version-4-integrations.md) for Version 4 and [here](/opentrade-sandbox/version-5-integrations.md) for Version 5. 

**You're now ready to get testing!**
