# Quadrata Sandbox

Use the passport issuer sandbox DApp to issue on-demand passports without the need for real user data. The tool can be found at [**https://sandbox.quadrata.com**](https://sandbox.quadrata.com)**.** 

{% hint style="info" %}
The passport uses custom wBTC, DAI and USDC for supported payment tokens. You can mint these tokens by calling the faucetMint() directly or by using the[ sandbox UI](https://sandbox.quadrata.com/faucet). These tokens have no value.
{% endhint %}

### First time using the sandbox

Connect your wallet to the sandbox DApp to mint a passport. The sandbox currently supports Goerli. You can [mine free Goerli ETH](https://goerli-faucet.pk910.de/), which you will need to submit transactions (e.g. minting and updating attributes) on Rinkeby testnet.

1. Click **Connect Wallet**. The sandbox connects to several wallet providers including MetaMask and those compatible with WalletConnect.
2. Switch your wallet to use the Goerli testnet environment.
3. Submit the wallet address you want to test. You will be prompted to submit attributes and mint a passport. 
4. Enter attribute values (see: [Supported attributes](/integration/introduction/passport-attributes.md)). Attribute values are pre-defined in production, but the sandbox DApp lets you customize them for testing purposes. \
   \
   **Note**: The sandbox will autogenerate a DID if you leave it blank. If you want to add this wallet to an existing entity, you can enter the DID for that entity. <br>
5. Click **Mint**.&#x20;
6. From your wallet, review and submit the transaction.

### Change the values of an existing test passport

You can change attribute values to test how different values affect your DApp.

1. Submit the wallet address you want to test. You will be prompted to update the attributes for your existing passport only if you've minted a passport for the submitted wallet.&#x20;
2. Update attribute values and click **Submit** (see: [Supported attributes](/integration/introduction/passport-attributes.md)).&#x20;
3. From your wallet, review and submit the transaction.
