Saved Addresses

The Address Book helps you manage and reuse frequently used addresses directly from your Membership Portal or mobile app.

Once you save an address, it appears as a shortcut when sending transactions—so you can select it quickly instead of copying and pasting every time.

Where to Find the Address Book

You can manage your saved addresses from:

Membership Portal (Web) Log in at Casa.io and navigate to Settings → Address Book. From here, you can add, label, edit, or delete saved addresses.

Mobile App Open the app and go to Settings → Address Book. The app opens a web view of the same Address Book page, allowing you to manage addresses directly.

Adding a Saved Address

You can save addresses for BTC, ETH, and supported ERC-20 tokens (USDC, USDT, stETH).

Steps:

1. Navigate to Settings → Address Book (in the web portal or app)
2. Tap Add Address
3. Enter the following information:
   • Label – Give your address a recognizable name
     • Must be unique (no duplicate labels allowed)
     • Between 1–32 characters, including spaces or emojis
   • Address – Paste your BTC or ETH address
     • For Ethereum addresses, select which asset it's used for (ETH, USDC, USDT, or stETH)
4. Review your entry
5. Tap Confirm

Your saved address now appears as a shortcut when sending that asset.

Editing or Removing an Address

To edit an address:

• You can only edit the asset type for Ethereum addresses (for example, switch from ETH to USDC)
• Select the address
• Choose Edit
• Adjust the asset type and tap Confirm

To remove an address:

• Select the address
• Choose Delete
• Confirm removal

Sending to a Saved Address

When you create a send transaction, your saved addresses appear automatically as shortcuts based on the asset you're sending.

Examples:

• Sending BTC → Only BTC addresses appear in your shortcuts
• Sending USDC → Only saved USDC addresses appear

Simply tap the shortcut and the address auto-fills into the destination field—no need to copy and paste, and no risk of sending to the wrong address.
