# Web App – User Guide

Using Common Web App on Testnets

### How to Use the Common Web App on Testnet

Follow these steps to get started with shielding your assets on testnet:

#### 1. Get testnet tokens

* Visit the [Common Faucet](https://shielder-faucet.vercel.app/)
* Select your desired network: **Aleph Zero EVM** **Testnet** or **Arbitrum Sepolia.**
* Paste your EVM address
* Click **“Get tokens”**

> 💡 Note: Some ERC-20 tokens–e.g. SPR (Spring)–might not show up automatically in your wallet, but they will be visible in the Common Web App.

#### 2. Shield your tokens

* Go to [app.common.fi](https://app.common.fi/)
* Connect your wallet. If this is your first time with a specific account, you need to sign a message in your wallet that will create the shielded account.
