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

• 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
• 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.

• Choose the token and amount you want to shield

• Approve the transaction in your wallet

3. Manage your shielded balance

• After shielding, check your balance on your shielded account

• You can now send the tokens from the shielded account to another address

🔐 For the best privacy, we recommend withdrawing to a new wallet address.
