Saved Addresses

Store your frequently used crypto addresses for quick access when sending Bitcoin and Ethereum

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.
